Abuse is not use. Running my JP23 in phoenix and somedays the bass knob says 136 degrees... when using it it cools in about 20 mins to under 90 degrees. Don't run low ohm loads and push everything to the max and heat wont be an issue. These are good amps... Will def get my business again, I promote using them to all my customers 👍
I've been into car audio since the old school Liner Power, Zapco, & Sherwood days. All of my cars have had upgraded stereos installed by myself. So I decided to pick up and Installed one of these JP2300v2 with the back plexiglass facing into the car running at 2ohms pushing two 12's kicker Q-Class. This amp gets down, hits the deep low notes beautifully, runs cool and never has overhead. I previously was using a Brazilian smart 3k bass and never even came close to the power and clean output that this JP2300v2 puts out. Solid amp great product, and it shipped out immediately 👍🏼
I've been nothing short of impressed with any product I've received with the D4S brand on it. As someone else said, anything in mass production can fail, but the important thing is how does the company stand behind their products? They can't guarantee your item wont break, but what they can do is make sure the customer receives fair treatment. And from what I've seen, JP and the crew at D4S is there for their customers.
I just got my amp last week. Coming from only Fosgate amps I was kinda skeptical but wanted to give yall a chance. Let me say I am very impressed and for the price I say it is the best amp. I noticed it did get a little hot and I had the same idea as you said. I noticed the fans on on the bottom and decided to raise the amp and let me tell you that’s all it needed. This video was much needed because I don’t think many people raise their amp for air flow
*Joe from Dallas Tx here… I am in the middle of a big build and I am considering using some JPs as I have faith in his products. But I think it’s laziness or lack of knowledge with most people not wanting to put in the small amount of extra effort to raise their amps. All amps are supposed to be on some form of standoffs due to every amp on the market having fans on the bottom. JP is right there’s multiple reasons why any amp will fell or heat up but as far as overheating, amps must sit on standoffs to breathe and stay cool and for best performance have external fans blowing through the amp under and top where the heatsink is
my amp fail was different, none of it was user error electrical was up to par to hold that amp. 14.7 volts, music at low volume kept hearing noises in subs then it destroyed almost every cap bout caught on fire. went straight to your warranty took 2 months and horrible customer service. even came to you personally for help and even you didnt really help me
Remember they have specific requirements for their warranties to be upheld and if any single one of them wasnt held up on your end they wont honor your warranty. If it truly was a defect and the amp was the issue that sucks and id be mad too. But they ask for very specific setup for the amps especially larger ones, and most amps dont just light on fire without something happening. Ive had every big name amp peoole say theyve had fires and issues with and ive never had issues 🤷♂️ ive had skar, taramps, audiopipe, and d4s all on completely wrong electrical, not enough power and still no issues
Many of us still remember that properly installed old school amps ran hot, like really hot(150-180f). Hell, it was common practice to mount amplifiers under the front seats, of which many had flaps of fabric to enclose and conceal the seat frame. These flaps created a heat pocket with the exhaust and transmission cooking our amplifiers and they just took it. I think these old memories and experiences have filtered into our common perception of how hot is too hot as it pertains to amplifiers today. I still run an Alpine 3552 at 4 x 4ohms and you can't hold your hand to the heat sink after jamming hard for a while. Today we channell huge current through heat sinks that are similar in size to my old 3552 and this is key to understanding why we are seeing an increase in heat induced failure. Back in the day, a 3 sided heat sink measuring 112sqin. of surface area, not including the additional area of the fins, may only need to dissipate the heat generated from producing 200wrms. Conversely, many modern 3k and 5k amps are smaller than my 3552, and often have no fins at all. All the JP series amplifiers that seem to have large finned heat sinks and many have forced air. So just remember folks, if you are experiencing overheating problems with your JP series amplifiers and you're still of the old school mindset about amplifier location and/or additional external ventilation, it is almost certainly your own fault if you end up cooking your amplifier.
I've been running a jp 13 for over a solid year on top of my underseat sub box seat sits right on top of it with some spacers and hasn't given me any issues yet I hear the fan always on but doesn't get hot.
I have a JP8 and a JP84 combo for 11 months now. On the JP8 I have the gain maxed out. I back off when the clip light comes on. No overheating at all. These amps are awesome. I just bought a JP95T for my second vehicle. Had for one week now it is awesome as well so far.
1. Never has my JP 33 gotten hot behind the rear seat of a ford superduty crewcab on an amp rack. Have only had 1 issue with my JP33 and the amp still played. The Bluetooth module in the amp for the bass knob failed. I'm waiting for it to get back in the next day or two to push the 12 zv6 again. D4S customer service was more than helpful and right on getting the problem fixed. Thanks D4S
I ordered a JP23 1.5 a few months back and I absolutely love it and it has never ran hot on me and I would definitely recommend them to anyone looking for a good quality amp and speaking of that I literally just ordered another JP23 just yesterday and I can't wait for it to come in, in my opinion they are top notch, Thanks JP keep on killing it Brother
Recently picked up my first D4S amp. It’s just a JP8.4 but I’m very satisfied so far. I have it on a vertical wall in an extended cab truck where the rear seat used to be. It’s elevated about 1" off the rack as I would’ve done 20+ years ago when I was an install tech. Just a good installation practice. Heat kills electronics.
I ran my JP63 at 15.5v, the power supply and mosfets blew less than a month brand new. However I replaced the mosfets and power supply. Spent 270US to repair it. I really hope it doesn't happen again. I really do love this amp because of it's power.
1000 people can post today that their d4s amps blew up. Not gonna stop me from shopping with Johnathan price. He's been good to me over the years. Never had an issue but had questions about my builds and he's personally responded to every question I've ever had. The loyalty will always trump any mechanical errors that may arise. D4S till its over 💪🏾
WE GOT YOU JP. DONT WORRY ABOUT THESE HATERS. YOU STAND BY YOUR PRODUCT. NOT LIKE SKAR😂. SKAR DOESNT EVEN SHOW FACE LIKE YOU DO. WE STAND BY YOU AND WORK HARD TO KEEP YOU KEEPING US BANGIN
As a former professional installer understand everything that you said in your video as far as consumers not being on the up-and-up and knowledgeable about power supplies as well as installation. Yes there is a fan on the bottom of your amplifiers but perhaps you should make the feet Mount taller so that that fan to circulate properly. A minor adjustment that may read your 1% problem. Just a few thoughts from an IASCCA finanlist and former professional installer.
I bought a refurbished jp33 and I've never had any trouble with it. Honestly it's by far the best quality Amp I've ever owned. Hey jp you know you're doing things right the more haters you'll have. Keep doing your thing bro. Thank you for the quality amps you provide.
Just bought a JP63 (red one). If you take your time and run the proper electrical as well as mounting it where air can actually pass on the top and bottom you should be fine. I like your products and I will continue to buy them.
Bought a JP95 and absolutely love it! I really think most people don't wire up systems properly or understand WHY it's important. Good wire and caps/batteries are pricey and add to the build more then the average installer is mabye prepared for or has little knowledge of. These are amazing amps for people that want high quality equipment at a price point they can afford!
Yea everytime I change something around I have to pull up a diagram to make sure I get the series/parallel wiring correct. It's so basic and I mostly remember how to do whatever I want to do but I have to double check and sometimes I make mistakes. Everyone else I know that has owned a system didn't know shit but would happily pull it apart, and move some wires around, and jus goof with their stuff trying to get more bass lmao That's pretty much the most simple thing to get right yet people so often don't even pull up a Google image to learn about how to hook their stuff up before they go to plugging shit in and turning knobs lol
I have a MM1002 jammed in the front fairing of my Harley running to 2 ohm speakers and I haven't had heat issues. I run it at highway volume for hours in Florida.
I been rocking my JP43, JP234 & JP84 for well over a year now and running them on upgraded electrical as we all should. I’m in the Inland Empire which gets pretty hot and I have never not once had any failures in my system. I stand by D4S equipment! I’m totally convinced that 99% of the so called failures are User error, either an overlooked defect in the install or over driven.
I live in vegas, picked a jp23 from your warehouse here. Honestly at first i was anoyed when it would be really hot i would turn on the car and it would be in temp protect after like 5 mins it will turn on. I just figured its was a vegas heat thing this only happens in vegas during the hotest days. But i believe its good thing in the long run ive had it for 3 years and no other issues. I do run at 4 ohm with 1 fi 15 it slaps so im happy. Oddly enough i have a jp234 that never goes into heat protect.
As a owner of a D4S amp. I'd tell you that even though they are marketed as a high power amp and they are. I rarely hear anyone mention the amazing sound quality. I've ran my amp for a year plus. I love it. If and when I ever need to replace it I will be looking at D4S again.
I had a ppi art series back in the day you could cook on top of it, and it would play all day every day running 3 10 jl Audio w6s v1s. I sold it to a buddy who still has it, and it still runs.
It's amazing how people will ignore the warning labels that specifically say must have proper electrical to run this amp but they spend time commenting false bs on social media. Read the directions and maybe the product info before you buy something goes a long way..
My JP23 was in protect mode because of extreme heat temperatures from hot weather but other than that mine works fine. I love how it performs. Any person with common sense knows that any amp can shut down due to extreme heat in hot weather conditions.
I have to agree with you on all your assignments of why people are experiencing a failure of the product due to not having an understanding of electrical theory because of them not upgrading some other component, as in doing what most call a BIG 3 awesome video by the way thanks
I have seen a good product with all negative reviews many times, I didn't believe the reviews and ended up buying the product with absolutely no problems. It happens with products that either work or they don't like an SD card reader, if it works there is nothing impressive about it and no review is left, but any faults and everyone will do a 1 star review.
The fact that most users on forums I've seen have pushed these well below their ohm rating sets a huge point for the durability of these amps. Don't do this if you don't know what you are doing and don't want a possible failure. I am looking to put a JP95 in my Ford Maverick because the power to price ratio is amazing. Love the color options and the old US amp designs. I will be purchasing soon, and think your products look great, may even give the 3 way comps a try!
Dude, ive been running my JP8 V1 since you did your original 1200 run. Over a year and i love this thing! Havent gotten over 109 degrees even on 90 degree days jamming hard. Haters are haters.
I’ve seen my JP8 hit 126 degrees, but that is in the summer in south Texas and only after a long 30 minute session at near clipping! It was warm to the touch, but not nearly as hot as other amps I’ve owned.
A cheap, helpful addition to each amp sale might be a rubber foot grommet or insert included? Just a thought, but that would eliminate the need to go source a spacer for the mounting feet.
Posting on Social Media is the quickest way to get a response. If you don't want them going to X, you have to have lightening fast email responses. Even then, if I have an issue I'm going to share the problem. Some companies are really good at handling issues, some blatantly lie and expect you not to realize 1+1=2. I had a 3d printer company not respond to emails about a hot end failure. It was an issue from assembly and the failure happened 3 times. The owner got pissy when I tweeted about it and said that no one else had an issue with them. He had no response to why the part that failed and needed replaced was LITERALLY the only part out of stock! Thank God for E3D V6's!
One question I've always had is if some of the bass knobs temperature readings are off. I got 3 jp8s 1 jp23 1jp95 and the 2 in one vehicle one will read 90 degrees and the other will read 130 degrees. I checked them with a temperature gun externally and both read 85 so I'm assuming the bass knob is off because they shouldn't be a 30 or more degree difference between the 2. And the jp23 is off in another car that also sits in the same garage as the one with 2 jp8s and a jp8⁴. Just a question but out of the 10 amps I have in total all the knobs read different degrees from the proper temperature that they are.
I ran my JP8 for over a year every single day with no over heating issues lol most ppl I see blow their D4S amps wire below the required ohm loads and don’t even have the electrical to run them that low 😅🔊
I definitely agree thought I've seen some jp amps have failures on good set up if set right with good power voltage set properly they can be good a amps
Ok, I own a JP234 four channel amp that failed literally a month into using it.... HOWEVER.... When I contacted down4sound, in a very irate way(I was pissed! But I was wrong!)..... Anyway, down4sound shipped out a brand new amp, no charge, no paperwork, nothing!! The second amp has been going strong over a year! Y'all have great products!!
The amps are solid, I'm still running an original jp 63, but the bass knobs? I know corners have to be cut a bit to bring the best at an affordable price but me personally, don't need the bass knobs, nothing beats feeling the temp when the amps are in reach and using a voltage meter
My Jp23v2 is running strong, honestly I love this amp more than my old school Lanzar amps! My Jp23v2 never over heats, doesn't doing anything my push my EVL'S to the maxx!!!! Keep doing good work JP!💪🏾💯
i just got 1 of jp23 v2 and i live in hot contry so when im runnin music loud i see temp up to 47c is that hot for that amp or should i hook up external fan?
I’ve never complained on any social platform about any product that being said had a jp43 that failed due to Bluetooth bass knob supposedly a problem with the v1 jp43. Went through the motions sent it in for warranty and it literally took 5 months to receive the amp back after getting the run around calling weekly. Oh it’s done should go out this week heard that about 8 times then the best part they told me oh it’s been done but we sent it to the original place of purchase dropping hertz then magically appeared in the Mail. Bottom line amps are great customer service sucks!! Maybe focus on that more
Been vibin' with my JP95 in my Focus ST. It does the job well, paired with a ct-sounds meso 10" at 1ohm. I do have a question though, how do these amplifiers operate under a smart charging alternator system? (i.e. when voltage fluctuates between 12.5v - 14.2v while driving like most newer cars these days) I disabled my battery management system for now so I'm charging at a constant 14v but I'm genuinely curious as to how the amplifier would handle the voltage fluctuations? Thanks
i have had my JP23 V2 for a little over a month and i love this amp. it does get hot, i have my Jp23 in direct wind on a mp rack above the sub box. i also have 3 half inch rubber grommets in each corner to raise the amp off the rack to help the fan on the bottom breath. as far as temp outside when the amp gets hot it was around 100f. my amp has never shut off due to it being hot tho. i have 2 15in skars 4ohm dvc wired to the amp at 1ohm. i have done the big 3 upgrade, and even before i did the big 3 i didn't have an issue with the lights dimming when the bass was hitting hard, and believe me the JP23 V2 will get your subs hitting hard asf did i mention i love my amp? lmmfao was thinking about getting another JP23 v2 and 2 more 15in skars. i also have a 1995 rockford fosgate punch 200ix pushing my 4 skar 6.5s in my doors.
@@THELIFEOFPRICE unfortunately I blew a second one, The first one was quick cause it was refurbished second one I was playing for a long time then puff smoke same spot as other amp this time I had dual 1/0 grounds and power, the cables are not hot just the amp with 1.2" spacers and ac vent aimed at it, I Dont Know what I'm doing wrong loved the way it sounded
I'm rocking JP34ab, and JP23v2 in a 05 Subaru outback pushing 3 skar zvx8s. There is no question these are the best Amps for the price in the market. I work for Custom Sounds and Tint we sell Rockford JL Kicker. Three of the biggest names in car audio. Hands down the JP amp are on par with all of these brands amps in SQ and Power. I recommend JP amps anytime anywhere.
I ran my two jp43’s at half ohm each at 15.5 for months & before then a jp83 at 1 ohm & have had no issues when I’ve had good electrical to power em. Most I’ve seen that have blown don’t have enough electrical to support or running bad loc’s that send bad signal as long as you got fans when running em half ohm & at 15.5 & have the electrical it’ll be fine 👊🏽
I absolutely love my JP23 amplifier it's a really good amp and as long as you take care of it properly it will last you and that goes with pretty much everything else
i have a jp 10.4 running my mids and highs and a jp83 running my 2 , 12in. american bass xfl 1222 wired at 2 ohms final impedance and i have had zero (0) issues ...my amps are out of sunlight and elevated approx. 1 inch from mounting surface i have 2 fans from an old pepsi refrigerator in a push pull config., as well as quality wiring and running an 80 ah lithium and a high quality mtx-49 interstate agm battery in factory location. and setting your gains correctly is another biggie in your amp or amps heat department, i can truly say these jp amplifiers are as good as it gets just be mindful in your setting up and you'll be fine and bumpin' for years to come. great work jp.....dj kenske phila., pa.
I bought a d4s jp32.2 and I could tell an immediate difference over a budget amp that dynos similar wattage. It sounded much better and had more punch. I push my amp to the max for an hour straight every day and have only hit 118f one time on a 100° day.
So I got a question my man. I live in California and it can get pretty hot here in the summer too and I’ve had other branded amps cut out music temporarily and stop playing bass during those hot summer days. Most of that is my own fault, I’ll admit, as the the user im the main contributor to the equipments failure during those extreme hot summer days when I know better than to max them out but I still do lol. But I’ve never had a class d 4 channel amp. This is going to be my first. Is it going to work at moderate to high volumes If mounted in the factory amp location behind the Carpets of my bmw for majority of the year ? I can understand the summer months can be brutal on aftermarket electronics but if I’m replacing the Oem amp I want to be sure the replacement will out perform the original and remain out of sight and still work during moderate to high volumes within reason?
I’ve got a JP8 and had it on a 12” Savard HiQ 12” dual 2 ohm sub. I live in south Texas and quit often in the summer would see the temp on the remote show 120 degrees when I would first turn it on. Even after playing at high volumes near clipping for 30 minutes, the highest temp I EVER saw was 126 degrees. The amp was mounted under my seat on 1/2” risers to allow air flow under the amp for the fan. LOVE the JP amps and eventually will be buying more!!! Thanks JP!!!!!
I want to update this comment. I now have my JP8 in my shed connected to a 10” subwoofer running 2 ohms. The amp is mounted UNDER my work bench, upside down, mounted to the underside of my work bench. Now, I live in south Texas. For those who don’t have a clue, it is HOT down here. How hot? Well, last week it was 110 degrees here, and my shop is not air conditioned. The power for the JP8 comes from a 300 amp/hr lithium battery bank which is recharged via 750 watts of solar. So the voltage is strong. Does the amp get hot? Absolutely it does. Could this be considered abuse? Maybe. Have I had a problem out of my JP8? Not at all. It normally runs around 125 degrees, 128 if I have the stereo cranked up. Am I happy with my JP8? You better believe it!!! This amp rocks!!!
Is there a certain amount of rule of thumb for height that you should space the amps up at? Is 1/4" enough? Or are we talking an inch or whatever it may be.
I got an 09 f150 supercab and the amp is under the back passenger seat with the floor vent under the front seats blowing ac towards it. It's s happy amp. Have all your wires matching. Power ground and same gauge speaker wire from amp to inside of box terminals to the sub itself. Should never overheat. You spend 500 to 1000 bucks on an amp don't go cheap and in a hurry on the fuse and wiring quality.
My JP23 ran great in the winter,soon as summer hit it will play about 5 10 minutes and go into protect, so I put a fan on it and it didn’t help at all, even when everything is off this amp is hot🤔
Had JP23's and JP234's in multiple vehicles and I have them in family members vehicles who are irresponsible - they run it 45c nonstop refuse to let me put an additional fan they keep clipping it too, it never goes into protect and has never given any of us an issue. Amazing amplifiers Really hoping my JP63 treats me as well as all the JP23's have, thousand for an amp is a lot for the average joe, but the power you advertise and the quality of your amplifiers and customer service... I would never go anywhere else. Team Down4Sound for life, please keep up all the excellent stuff that has been going on at D4S!!!!!
JP glad you post these videos man it shows how much you care about your brand and what your customers mean to you. People always want to whine and cry but there the same one who don’t follow the boundaries you have set for them.
I have my amps under the front seats but I'm always using the AC blowing to front and foots (dont know how's called in English) the cold air enters one side and the fans exhaust the heat.
Many don't realize when they shrink these amps down in the newer versions with increased output you are going to have a hotter amp. Best to add a fan rack.
I'm glad that you made this video. Every install place here in Minnesota speak real poorly about your amps and they don't wanna even install them. They try to sell you mainstream like kicker or JL audio. We need more places that know the good in your product and stop hating on your stuff. I'm running the jp23 v2 in my Atlas and never had an issue with anything. It's loud and the sound quality is amazing. Good job on your amps JP. F the haters. Keep doing what you do and keep being number 1!
You're doing exactly what your haters want you to do. You're feeding into it, addressing them and giving them their 15 minutes of fame. Now you're giving them the satisfaction of thinking that they're living in your mind rent free. The 1% irked you enough to the point where you felt it needed to be addressed. Haters gonna hate regardless of what you say or do. You're better than that. Logistically speaking, you should welcome the haters. Having haters only solidifies success.
i agree with this 100% haters hate on those who are doing what they cant or are to lazy to do. like myself i do love my haters, they push me to do more. You know youre dong what ever it is right if people are hating on it. jp in this case 100% did what the haters wanted him to do. now they see they are getting to him its only going to increase never fails.
JP is oldschool minded and doesn't understand! But hey atleast us fans of his product are here to back him up. Plus there's a video debunking all this now anyway. Lol
@@THELIFEOFPRICE you cant help those who dont wanna learn, what you said in your video is electronics 101 it applies to every electronic. no matter how you try to help people youre not gonna stop the hating. all do respect for the 1% you spoke on its not even worth your time. Ive delt with some of your employees as wel las you personally and ill be the 1st to say deff not worth your time. haters that dont listen well see how much money they keep wasting before they wake up and start listening so they can enjoy their toys vs keep destroying them. most amp issues are user error. fact is outside of the dealer i use you and your company is one of the best in terms of customer service. yes ive delt with sundown and dc audio compared to you they are a joke.
@@THELIFEOFPRICE people who take the word of haters as gospel & then regurgitate misinformation aren't worth the time & energy. The people you're trying to help understand things...all you're doing is giving them the option to listen to your detractors or listen to the guy that has a financial stake in the prodct. If they took what you're saying as fact without due diligence...how is that any different? The smart ones will listen to the unbias with nothing to lose or gain ie Big D Wiz
Mine went into temp protect at 130 degrees today I moved it to a new spot and just didn’t have enough airflow so it’s my fault love my jp23 kinda wish I went with a 33 tho
Anything mass produced is obviously prone to failure... Failure is a part of the learning and growing process... There are reasons for failure, and THATS what needs to be addressed... Keep doing what your doing JP... Even Haters have their own way not following thru the process...😎
heard nothing but bad things about the overheating, had me stay away from the JP amps.. but, i recently just won a raffle for a new JP83 and i'm looking forward to see how it performs. Replacing my taramps big boss 8k, have plenty of electrical and fans on the amps. Im sure itll go well
I'm old school bass head. Common sense states if you push an amp hard you better cool it. You live in hot areas of the country you better cool it. I ran extra fans on mine. Williston Labs have tested JP amps. These are solid amps. Take care when installing them and they will last. From what I see these are quality.
I haven't had an issue but I also know what I'm doing I almost always run an external fan which really you need to do with any brand if you're going to be wiring low and pushing the amp to its limits
Let be honest my co worker had the first jp amps in hi car and it work crazy good still to this day no problems love d4sounds best place best products in the game
Abuse is not use. Running my JP23 in phoenix and somedays the bass knob says 136 degrees... when using it it cools in about 20 mins to under 90 degrees. Don't run low ohm loads and push everything to the max and heat wont be an issue. These are good amps... Will def get my business again, I promote using them to all my customers 👍
Or buy a fkn orion n get fked if ur amp has an issue at 135 degrees lmfao smart comment smfh
EXACTLY 💯 My jp 23 been kicking for a year now in North Mississippi!!
“You would be in protect too in 125 degree heat” I almost died lol. These are solid amps. A lot of times it’s user error.
I couldn't believe that he said that, but imo it was much needed, because some people are just plain morons and don't know basis 101.
I've been into car audio since the old school Liner Power, Zapco, & Sherwood days. All of my cars have had upgraded stereos installed by myself. So I decided to pick up and Installed one of these JP2300v2 with the back plexiglass facing into the car running at 2ohms pushing two 12's kicker Q-Class. This amp gets down, hits the deep low notes beautifully, runs cool and never has overhead. I previously was using a Brazilian smart 3k bass and never even came close to the power and clean output that this JP2300v2 puts out. Solid amp great product, and it shipped out immediately 👍🏼
Bullshit
i have two q 12s with a qbomb box at .5 ohms and its overheating fast
Because it's pos amp
@@darthmaul9911You're running a 1 ohm stable amp at 0.5 and think the heat is a design issue or manufacturer defect?
Never even heard there was a issue. Just recommended an amp combo to a cousin. Keep up the good work JP 💪🏻
I've been nothing short of impressed with any product I've received with the D4S brand on it. As someone else said, anything in mass production can fail, but the important thing is how does the company stand behind their products? They can't guarantee your item wont break, but what they can do is make sure the customer receives fair treatment. And from what I've seen, JP and the crew at D4S is there for their customers.
I just got my amp last week. Coming from only Fosgate amps I was kinda skeptical but wanted to give yall a chance. Let me say I am very impressed and for the price I say it is the best amp. I noticed it did get a little hot and I had the same idea as you said. I noticed the fans on on the bottom and decided to raise the amp and let me tell you that’s all it needed. This video was much needed because I don’t think many people raise their amp for air flow
*Joe from Dallas Tx here…
I am in the middle of a big build and I am considering using some JPs as I have faith in his products. But I think it’s laziness or lack of knowledge with most people not wanting to put in the small amount of extra effort to raise their amps. All amps are supposed to be on some form of standoffs due to every amp on the market having fans on the bottom. JP is right there’s multiple reasons why any amp will fell or heat up but as far as overheating, amps must sit on standoffs to breathe and stay cool and for best performance have external fans blowing through the amp under and top where the heatsink is
my amp fail was different, none of it was user error electrical was up to par to hold that amp. 14.7 volts, music at low volume kept hearing noises in subs then it destroyed almost every cap bout caught on fire. went straight to your warranty took 2 months and horrible customer service. even came to you personally for help and even you didnt really help me
Remember they have specific requirements for their warranties to be upheld and if any single one of them wasnt held up on your end they wont honor your warranty. If it truly was a defect and the amp was the issue that sucks and id be mad too. But they ask for very specific setup for the amps especially larger ones, and most amps dont just light on fire without something happening. Ive had every big name amp peoole say theyve had fires and issues with and ive never had issues 🤷♂️ ive had skar, taramps, audiopipe, and d4s all on completely wrong electrical, not enough power and still no issues
Many of us still remember that properly installed old school amps ran hot, like really hot(150-180f).
Hell, it was common practice to mount amplifiers under the front seats, of which many had flaps of fabric to enclose and conceal the seat frame.
These flaps created a heat pocket with the exhaust and transmission cooking our amplifiers and they just took it.
I think these old memories and experiences have filtered into our common perception of how hot is too hot as it pertains to amplifiers today.
I still run an Alpine 3552 at 4 x 4ohms and you can't hold your hand to the heat sink after jamming hard for a while.
Today we channell huge current through heat sinks that are similar in size to my old 3552 and this is key to understanding why we are seeing an increase in heat induced failure.
Back in the day, a 3 sided heat sink measuring 112sqin. of surface area, not including the additional area of the fins, may only need to dissipate the heat generated from producing 200wrms. Conversely, many modern 3k and 5k amps are smaller than my 3552, and often have no fins at all.
All the JP series amplifiers that seem to have large finned heat sinks and many have forced air.
So just remember folks, if you are experiencing overheating problems with your JP series amplifiers and you're still of the old school mindset about amplifier location and/or additional external ventilation, it is almost certainly your own fault if you end up cooking your amplifier.
I've been running a jp 13 for over a solid year on top of my underseat sub box seat sits right on top of it with some spacers and hasn't given me any issues yet I hear the fan always on but doesn't get hot.
I have a JP8 and a JP84 combo for 11 months now. On the JP8 I have the gain maxed out. I back off when the clip light comes on. No overheating at all. These amps are awesome. I just bought a JP95T for my second vehicle. Had for one week now it is awesome as well so far.
I've been running my JP6300 for a while and it's doing just fine. Thanks for the video!
1. Never has my JP 33 gotten hot behind the rear seat of a ford superduty crewcab on an amp rack. Have only had 1 issue with my JP33 and the amp still played. The Bluetooth module in the amp for the bass knob failed. I'm waiting for it to get back in the next day or two to push the 12 zv6 again. D4S customer service was more than helpful and right on getting the problem fixed. Thanks D4S
I ordered a JP23 1.5 a few months back and I absolutely love it and it has never ran hot on me and I would definitely recommend them to anyone looking for a good quality amp and speaking of that I literally just ordered another JP23 just yesterday and I can't wait for it to come in, in my opinion they are top notch, Thanks JP keep on killing it Brother
Recently picked up my first D4S amp. It’s just a JP8.4 but I’m very satisfied so far. I have it on a vertical wall in an extended cab truck where the rear seat used to be. It’s elevated about 1" off the rack as I would’ve done 20+ years ago when I was an install tech. Just a good installation practice. Heat kills electronics.
I ran my JP63 at 15.5v, the power supply and mosfets blew less than a month brand new. However I replaced the mosfets and power supply. Spent 270US to repair it. I really hope it doesn't happen again. I really do love this amp because of it's power.
1000 people can post today that their d4s amps blew up. Not gonna stop me from shopping with Johnathan price. He's been good to me over the years. Never had an issue but had questions about my builds and he's personally responded to every question I've ever had. The loyalty will always trump any mechanical errors that may arise. D4S till its over 💪🏾
WE GOT YOU JP. DONT WORRY ABOUT THESE HATERS. YOU STAND BY YOUR PRODUCT. NOT LIKE SKAR😂. SKAR DOESNT EVEN SHOW FACE LIKE YOU DO. WE STAND BY YOU AND WORK HARD TO KEEP YOU KEEPING US BANGIN
What's up brother been a min, screw the haters, all amps can blow or overheat. Dudes today run everything at .5 ohms expecting them to not overheat
Been saying this! Most the pple bashing brands or misinforming DO NOT HAVE PROPER ELECTRICAL to use this equipment! Love your videos!
I never thought of using external fans for my amp thanks for the info
As a former professional installer understand everything that you said in your video as far as consumers not being on the up-and-up and knowledgeable about power supplies as well as installation. Yes there is a fan on the bottom of your amplifiers but perhaps you should make the feet Mount taller so that that fan to circulate properly. A minor adjustment that may read your 1% problem. Just a few thoughts from an IASCCA finanlist and former professional installer.
They are spaced up but if people have like really thick carpet it won’t matter. Plus it will make them easier to break. Always a trade off :/
I bought a refurbished jp33 and I've never had any trouble with it. Honestly it's by far the best quality Amp I've ever owned. Hey jp you know you're doing things right the more haters you'll have. Keep doing your thing bro. Thank you for the quality amps you provide.
Just bought a JP63 (red one). If you take your time and run the proper electrical as well as mounting it where air can actually pass on the top and bottom you should be fine. I like your products and I will continue to buy them.
JP keep doing your best. I love the beat down of your amps.
Bought a JP95 and absolutely love it! I really think most people don't wire up systems properly or understand WHY it's important. Good wire and caps/batteries are pricey and add to the build more then the average installer is mabye prepared for or has little knowledge of. These are amazing amps for people that want high quality equipment at a price point they can afford!
Yea everytime I change something around I have to pull up a diagram to make sure I get the series/parallel wiring correct. It's so basic and I mostly remember how to do whatever I want to do but I have to double check and sometimes I make mistakes.
Everyone else I know that has owned a system didn't know shit but would happily pull it apart, and move some wires around, and jus goof with their stuff trying to get more bass lmao
That's pretty much the most simple thing to get right yet people so often don't even pull up a Google image to learn about how to hook their stuff up before they go to plugging shit in and turning knobs lol
I have a MM1002 jammed in the front fairing of my Harley running to 2 ohm speakers and I haven't had heat issues. I run it at highway volume for hours in Florida.
I been rocking my JP43, JP234 & JP84 for well over a year now and running them on upgraded electrical as we all should. I’m in the Inland Empire which gets pretty hot and I have never not once had any failures in my system. I stand by D4S equipment! I’m totally convinced that 99% of the so called failures are User error, either an overlooked defect in the install or over driven.
I live in vegas, picked a jp23 from your warehouse here. Honestly at first i was anoyed when it would be really hot i would turn on the car and it would be in temp protect after like 5 mins it will turn on. I just figured its was a vegas heat thing this only happens in vegas during the hotest days. But i believe its good thing in the long run ive had it for 3 years and no other issues. I do run at 4 ohm with 1 fi 15 it slaps so im happy. Oddly enough i have a jp234 that never goes into heat protect.
As a owner of a D4S amp. I'd tell you that even though they are marketed as a high power amp and they are. I rarely hear anyone mention the amazing sound quality. I've ran my amp for a year plus. I love it. If and when I ever need to replace it I will be looking at D4S again.
Maybe you can start including spacers with your amps. Atleast an added option from the dropdown menu for extra few bucks.
Or people can just take their ass to a hardware store or shit even Walmart and get them themselves!
I had a ppi art series back in the day you could cook on top of it, and it would play all day every day running 3 10 jl Audio w6s v1s. I sold it to a buddy who still has it, and it still runs.
I’ve been pounding my JP23 for about a year now. Never overheated, not once. I’ve had no problems or complaints.
It's amazing how people will ignore the warning labels that specifically say must have proper electrical to run this amp but they spend time commenting false bs on social media. Read the directions and maybe the product info before you buy something goes a long way..
My JP23 was in protect mode because of extreme heat temperatures from hot weather but other than that mine works fine. I love how it performs. Any person with common sense knows that any amp can shut down due to extreme heat in hot weather conditions.
Some things will never seem to change. SMH be thankful that JP is willing to give you a quality product at a better than reasonable price.
I have to agree with you on all your assignments of why people are experiencing a failure of the product due to not having an understanding of electrical theory because of them not upgrading some other component, as in doing what most call a BIG 3 awesome video by the way thanks
If it’s built by man it’s bound to fail. I’m an old school bass head and I can’t wait to try out one of your JP amps 💪🏽👍🏽😎
I have seen a good product with all negative reviews many times, I didn't believe the reviews and ended up buying the product with absolutely no problems.
It happens with products that either work or they don't like an SD card reader, if it works there is nothing impressive about it and no review is left, but any faults and everyone will do a 1 star review.
The fact that most users on forums I've seen have pushed these well below their ohm rating sets a huge point for the durability of these amps. Don't do this if you don't know what you are doing and don't want a possible failure. I am looking to put a JP95 in my Ford Maverick because the power to price ratio is amazing. Love the color options and the old US amp designs. I will be purchasing soon, and think your products look great, may even give the 3 way comps a try!
Dude, ive been running my JP8 V1 since you did your original 1200 run. Over a year and i love this thing! Havent gotten over 109 degrees even on 90 degree days jamming hard. Haters are haters.
I’ve seen my JP8 hit 126 degrees, but that is in the summer in south Texas and only after a long 30 minute session at near clipping! It was warm to the touch, but not nearly as hot as other amps I’ve owned.
Ive had mine hit 148 degrees but it still didnt protect
A cheap, helpful addition to each amp sale might be a rubber foot grommet or insert included? Just a thought, but that would eliminate the need to go source a spacer for the mounting feet.
Posting on Social Media is the quickest way to get a response. If you don't want them going to X, you have to have lightening fast email responses. Even then, if I have an issue I'm going to share the problem. Some companies are really good at handling issues, some blatantly lie and expect you not to realize 1+1=2. I had a 3d printer company not respond to emails about a hot end failure. It was an issue from assembly and the failure happened 3 times. The owner got pissy when I tweeted about it and said that no one else had an issue with them. He had no response to why the part that failed and needed replaced was LITERALLY the only part out of stock! Thank God for E3D V6's!
One question I've always had is if some of the bass knobs temperature readings are off. I got 3 jp8s 1 jp23 1jp95 and the 2 in one vehicle one will read 90 degrees and the other will read 130 degrees. I checked them with a temperature gun externally and both read 85 so I'm assuming the bass knob is off because they shouldn't be a 30 or more degree difference between the 2. And the jp23 is off in another car that also sits in the same garage as the one with 2 jp8s and a jp8⁴.
Just a question but out of the 10 amps I have in total all the knobs read different degrees from the proper temperature that they are.
You'd think this is common knowledge. Curious though, why not design amp with longer 'feet/legs' so it CAN'T be mounted flush to surface?🤔
I ran my JP8 for over a year every single day with no over heating issues lol most ppl I see blow their D4S amps wire below the required ohm loads and don’t even have the electrical to run them that low 😅🔊
I definitely agree thought I've seen some jp amps have failures on good set up if set right with good power voltage set properly they can be good a amps
Ok, I own a JP234 four channel amp that failed literally a month into using it.... HOWEVER.... When I contacted down4sound, in a very irate way(I was pissed! But I was wrong!)..... Anyway, down4sound shipped out a brand new amp, no charge, no paperwork, nothing!! The second amp has been going strong over a year! Y'all have great products!!
The amps are solid, I'm still running an original jp 63, but the bass knobs? I know corners have to be cut a bit to bring the best at an affordable price but me personally, don't need the bass knobs, nothing beats feeling the temp when the amps are in reach and using a voltage meter
I have a jp23 1.5 and I have not had a problem yet temperatures never got over 110 degrees. I have never even heard my fan which kicks on at 120
do these work or do you have an amp that works up in the 16 volt range thats been the main reason i havent got a jp 43 or 63
The haters are going to hate no stopping that lol. JP I love my D4s amp please keep up the good work my friend
My Jp23v2 is running strong, honestly I love this amp more than my old school Lanzar amps! My Jp23v2 never over heats, doesn't doing anything my push my EVL'S to the maxx!!!! Keep doing good work JP!💪🏾💯
i just got 1 of jp23 v2 and i live in hot contry so when im runnin music loud i see temp up to 47c is that hot for that amp or should i hook up external fan?
I’ve never complained on any social platform about any product that being said had a jp43 that failed due to Bluetooth bass knob supposedly a problem with the v1 jp43. Went through the motions sent it in for warranty and it literally took 5 months to receive the amp back after getting the run around calling weekly. Oh it’s done should go out this week heard that about 8 times then the best part they told me oh it’s been done but we sent it to the original place of purchase dropping hertz then magically appeared in the Mail. Bottom line amps are great customer service sucks!! Maybe focus on that more
Been vibin' with my JP95 in my Focus ST. It does the job well, paired with a ct-sounds meso 10" at 1ohm. I do have a question though, how do these amplifiers operate under a smart charging alternator system? (i.e. when voltage fluctuates between 12.5v - 14.2v while driving like most newer cars these days) I disabled my battery management system for now so I'm charging at a constant 14v but I'm genuinely curious as to how the amplifier would handle the voltage fluctuations? Thanks
i have had my JP23 V2 for a little over a month and i love this amp. it does get hot, i have my Jp23 in direct wind on a mp rack above the sub box. i also have 3 half inch rubber grommets in each corner to raise the amp off the rack to help the fan on the bottom breath. as far as temp outside when the amp gets hot it was around 100f. my amp has never shut off due to it being hot tho. i have 2 15in skars 4ohm dvc wired to the amp at 1ohm. i have done the big 3 upgrade, and even before i did the big 3 i didn't have an issue with the lights dimming when the bass was hitting hard, and believe me the JP23 V2 will get your subs hitting hard asf did i mention i love my amp? lmmfao was thinking about getting another JP23 v2 and 2 more 15in skars. i also have a 1995 rockford fosgate punch 200ix pushing my 4 skar 6.5s in my doors.
Which is better JP40+JP630 or two LTO 6.0s? Can’t decide what I want to go with and can’t find hardly any reviews on the JP line of battery’s
I have been thinking about grabbing a jp77 but have been iffy because of some of the hate.
MY JP 77 HAS DUAL FANS AND DOESN'T DIP BELOW 14V FULL TILT. EXCEEDING MY EXPECTATIONS SO FAR! KEEP DOING WHAT YOU DO BROTHER!
Would you consider a cyber 12k stock Alternator enough electrical support for the jp23 @ 1ohm
Plenty 😊
@@THELIFEOFPRICE unfortunately I blew a second one,
The first one was quick cause it was refurbished second one I was playing for a long time then puff smoke same spot as other amp this time I had dual 1/0 grounds and power, the cables are not hot just the amp with 1.2" spacers and ac vent aimed at it, I Dont Know what I'm doing wrong loved the way it sounded
I'm rocking JP34ab, and JP23v2 in a 05 Subaru outback pushing 3 skar zvx8s. There is no question these are the best Amps for the price in the market. I work for Custom Sounds and Tint we sell Rockford JL Kicker. Three of the biggest names in car audio. Hands down the JP amp are on par with all of these brands amps in SQ and Power. I recommend JP amps anytime anywhere.
I ran my two jp43’s at half ohm each at 15.5 for months & before then a jp83 at 1 ohm & have had no issues when I’ve had good electrical to power em. Most I’ve seen that have blown don’t have enough electrical to support or running bad loc’s that send bad signal as long as you got fans when running em half ohm & at 15.5 & have the electrical it’ll be fine 👊🏽
My dad recently got his hearing back. He wanted to put a 500w system in his car. So i got him a JP3 signed by JP himself. He's more than happy.
I absolutely love my JP23 amplifier it's a really good amp and as long as you take care of it properly it will last you and that goes with pretty much everything else
Dude for real me too. I have two jp23’s strapped to .5 and they only ever got too hot when it was like July and August on a 95+ degree day lol.
Im running a jp23 on my home system running 1 15. Now i want the jp 83 for my 3 15s in my truck
i have a jp 10.4 running my mids and highs and a jp83 running my 2 , 12in. american bass xfl 1222 wired at 2 ohms final impedance and i have had zero (0) issues ...my amps are out of sunlight and elevated approx. 1 inch from mounting surface i have 2 fans from an old pepsi refrigerator in a push pull config., as well as quality wiring and running an 80 ah lithium and a high quality mtx-49 interstate agm battery in factory location. and setting your gains correctly is another biggie in your amp or amps heat department, i can truly say these jp amplifiers are as good as it gets just be mindful in your setting up and you'll be fine and bumpin' for years to come. great work jp.....dj kenske phila., pa.
I bought a d4s jp32.2 and I could tell an immediate difference over a budget amp that dynos similar wattage. It sounded much better and had more punch. I push my amp to the max for an hour straight every day and have only hit 118f one time on a 100° day.
My bass knob is junk
JP what’s the name of the outro song you use to play on you videos?
So I got a question my man. I live in California and it can get pretty hot here in the summer too and I’ve had other branded amps cut out music temporarily and stop playing bass during those hot summer days. Most of that is my own fault, I’ll admit, as the the user im the main contributor to the equipments failure during those extreme hot summer days when I know better than to max them out but I still do lol.
But I’ve never had a class d 4 channel amp. This is going to be my first. Is it going to work at moderate to high volumes If mounted in the factory amp location behind the Carpets of my bmw for majority of the year ? I can understand the summer months can be brutal on aftermarket electronics but if I’m replacing the Oem amp I want to be sure the replacement will out perform the original and remain out of sight and still work during moderate to high volumes within reason?
I’ve got a JP8 and had it on a 12” Savard HiQ 12” dual 2 ohm sub. I live in south Texas and quit often in the summer would see the temp on the remote show 120 degrees when I would first turn it on. Even after playing at high volumes near clipping for 30 minutes, the highest temp I EVER saw was 126 degrees.
The amp was mounted under my seat on 1/2” risers to allow air flow under the amp for the fan.
LOVE the JP amps and eventually will be buying more!!! Thanks JP!!!!!
I want to update this comment. I now have my JP8 in my shed connected to a 10” subwoofer running 2 ohms. The amp is mounted UNDER my work bench, upside down, mounted to the underside of my work bench. Now, I live in south Texas. For those who don’t have a clue, it is HOT down here. How hot? Well, last week it was 110 degrees here, and my shop is not air conditioned. The power for the JP8 comes from a 300 amp/hr lithium battery bank which is recharged via 750 watts of solar. So the voltage is strong.
Does the amp get hot? Absolutely it does. Could this be considered abuse? Maybe. Have I had a problem out of my JP8? Not at all. It normally runs around 125 degrees, 128 if I have the stereo cranked up. Am I happy with my JP8? You better believe it!!! This amp rocks!!!
I"ve been running my JP23 at 0.5 ohm for over a year and I have never had a problem with and I've never seen it get over 105 degrees
will a jp33 be ok on a .67 ohm
Is there a certain amount of rule of thumb for height that you should space the amps up at? Is 1/4" enough? Or are we talking an inch or whatever it may be.
If there was they should’ve put taller feet on them. A better design would allow air to flow from heat sink to heat sink
I got an 09 f150 supercab and the amp is under the back passenger seat with the floor vent under the front seats blowing ac towards it. It's s happy amp. Have all your wires matching. Power ground and same gauge speaker wire from amp to inside of box terminals to the sub itself. Should never overheat. You spend 500 to 1000 bucks on an amp don't go cheap and in a hurry on the fuse and wiring quality.
My JP23 ran great in the winter,soon as summer hit it will play about 5 10 minutes and go into protect, so I put a fan on it and it didn’t help at all, even when everything is off this amp is hot🤔
Had JP23's and JP234's in multiple vehicles and I have them in family members vehicles who are irresponsible - they run it 45c nonstop refuse to let me put an additional fan they keep clipping it too, it never goes into protect and has never given any of us an issue. Amazing amplifiers
Really hoping my JP63 treats me as well as all the JP23's have, thousand for an amp is a lot for the average joe, but the power you advertise and the quality of your amplifiers and customer service... I would never go anywhere else. Team Down4Sound for life, please keep up all the excellent stuff that has been going on at D4S!!!!!
I have a JP 23v2 pushing 4 8’s all day in California summer heat with no issues. Haters gunna hate.
I been trying to reach warranty for the longest time any suggestions
Log into your Down4Sound account and go to your order and click send message and create a return.
I had a JP8 and the JP84 and the only problem I had with mine is the speaker terminal. The threads pulled out of the aluminum.
What jp amp should I get with fi neo 4.11 18 rated 4500rms 15k burp jp 43 or jp 93 and send it
I’ve had mine for a few years now and no problems. But I don’t run them maxed out either.
Can we do a video on the new JP mini 4channel and over view
JP glad you post these videos man it shows how much you care about your brand and what your customers mean to you. People always want to whine and cry but there the same one who don’t follow the boundaries you have set for them.
I have my amps under the front seats but I'm always using the AC blowing to front and foots (dont know how's called in English) the cold air enters one side and the fans exhaust the heat.
Many don't realize when they shrink these amps down in the newer versions with increased output you are going to have a hotter amp. Best to add a fan rack.
I'm glad that you made this video. Every install place here in Minnesota speak real poorly about your amps and they don't wanna even install them. They try to sell you mainstream like kicker or JL audio. We need more places that know the good in your product and stop hating on your stuff. I'm running the jp23 v2 in my Atlas and never had an issue with anything. It's loud and the sound quality is amazing. Good job on your amps JP. F the haters. Keep doing what you do and keep being number 1!
That’s where I come in wsp Minnesota sundowns user 2jp63 wired .5 ohms the caps blow on them sometimes but I got my warrenty
You're doing exactly what your haters want you to do. You're feeding into it, addressing them and giving them their 15 minutes of fame. Now you're giving them the satisfaction of thinking that they're living in your mind rent free. The 1% irked you enough to the point where you felt it needed to be addressed. Haters gonna hate regardless of what you say or do. You're better than that. Logistically speaking, you should welcome the haters. Having haters only solidifies success.
i agree with this 100% haters hate on those who are doing what they cant or are to lazy to do. like myself i do love my haters, they push me to do more. You know youre dong what ever it is right if people are hating on it. jp in this case 100% did what the haters wanted him to do. now they see they are getting to him its only going to increase never fails.
It’s also helping people understand things 😊
JP is oldschool minded and doesn't understand! But hey atleast us fans of his product are here to back him up. Plus there's a video debunking all this now anyway. Lol
@@THELIFEOFPRICE you cant help those who dont wanna learn, what you said in your video is electronics 101 it applies to every electronic. no matter how you try to help people youre not gonna stop the hating. all do respect for the 1% you spoke on its not even worth your time. Ive delt with some of your employees as wel las you personally and ill be the 1st to say deff not worth your time. haters that dont listen well see how much money they keep wasting before they wake up and start listening so they can enjoy their toys vs keep destroying them. most amp issues are user error. fact is outside of the dealer i use you and your company is one of the best in terms of customer service. yes ive delt with sundown and dc audio compared to you they are a joke.
@@THELIFEOFPRICE people who take the word of haters as gospel & then regurgitate misinformation aren't worth the time & energy. The people you're trying to help understand things...all you're doing is giving them the option to listen to your detractors or listen to the guy that has a financial stake in the prodct. If they took what you're saying as fact without due diligence...how is that any different? The smart ones will listen to the unbias with nothing to lose or gain ie Big D Wiz
I'd love to do a build using the jp amps man. Those things are tanks!!
Mine went into temp protect at 130 degrees today I moved it to a new spot and just didn’t have enough airflow so it’s my fault love my jp23 kinda wish I went with a 33 tho
I have 4 D4S amps and I push them 2 the limit every day and I never. Ever have a problem they are great amps . One of the best brand I've used.
Anything mass produced is obviously prone to failure... Failure is a part of the learning and growing process... There are reasons for failure, and THATS what needs to be addressed... Keep doing what your doing JP... Even Haters have their own way not following thru the process...😎
Need extra battery and caps or alternator pow3r to make power or all three
heard nothing but bad things about the overheating, had me stay away from the JP amps.. but, i recently just won a raffle for a new JP83 and i'm looking forward to see how it performs. Replacing my taramps big boss 8k, have plenty of electrical and fans on the amps. Im sure itll go well
My OG jp23 v1 still going strong after 4 or so years. Yeah it's get warm in summer but that's what fans are for😅
I'm old school bass head. Common sense states if you push an amp hard you better cool it. You live in hot areas of the country you better cool it. I ran extra fans on mine. Williston Labs have tested JP amps. These are solid amps. Take care when installing them and they will last. From what I see these are quality.
I haven't had an issue but I also know what I'm doing I almost always run an external fan which really you need to do with any brand if you're going to be wiring low and pushing the amp to its limits
Mine just started to over heat idk if it’s my amp of something else
Let be honest my co worker had the first jp amps in hi car and it work crazy good still to this day no problems love d4sounds best place best products in the game
