I had a JP amp that was DOA and y'all totally took care of me getting a replacement, it was a China one but I love they still come with a clip light That D4S service will be what keeps me coming back
Brazilian amp technology has improved greatly, I still prefer Korean amp but right now I have nothing but Brazilian in my build except for my highs amp. These Brazilian amps aren't no joke, I have an MD12K on 2 18s no wall and she's hitting 150+ haven't put a meter on it yet.
I brought a sound digital 8k and it did good till it got hot..bad noise, bad signal in my sub and didn't do as good as my salt 4..I ended up giving it away..
@@allenscott5773 yea if you run Brazilian your head unit has to have good crossovers or run a dsp. That's really my only complaint about Brazilian amps.
I had a jp23 amp pushing a American bass 15 xfl for a year. I’m a over the road truck driver and I bump for 5-8 hours straight sometimes. No issues at all with amp or sub. I upgraded to a avatar 15 Stu so I needed more power so I got a Taramps smart 5k and it’s a amazing powerhouse. Same thing I’ve had it for a year and bump for 5-8 hours. Only issue with this set up is my sub gets real hot after about 5 hours depending on music. But it is way more power. The jp does have better SQ no doubt. Next upgrade will be a jp Korean and probably a deaf bonce.
The thing is it's all parts quality used not the topology. Brazilian built full bridge use extremely cheap parts to keep costs low. This is why they fail more often. Not because it's a full bridge. The Powerus line of Brazilian amps are built as high quality as a Korean half-bridge but they will cost you as much as a Korean half-bridge because you're paying for the parts used. Same with most Chinese amps. Their half-bridge and full bridge designs for the most part are made with cheap parts to keep the cost down. This is due to whoever is having them built requesting these parts. You can have a Chinese amp that's just as high quality and rugged as a Korean made amplifier but whoever is having it built would need to pay for that quality which translates to higher prices which most don't want to do. Quantity over Quality. Korean amps are nothing special except they use high end parts thus making their durability much much higher. People need to stop attributing the topology to quality. Korean Full bridge are just as quality and durable as their half-bridge amps. No matter where you buy from it's all about what parts you tell them to use not where they are made or if it's full bridge vs half bridge.
I always promote JP Amplifiers, even though I do not own one, because they dyno above ratings at certified, uncertified and dynamic with plenty of headroom! Way to go JP!
I have a 34ab and a 33,I love both of them because they have your name behind it and its great quality,I never second guess when buying from you jp!! Regardless where it's made,I'll still love it
I have an original jp23 and the selling point was introductory pricing for a Korean amp, not Chinese. And now I am having an issue with I’m guessing the heat sink, and can’t afford to upgrade to a 33. That is honestly a huge bummer and disappointment.
An introductory pricing for a jp23 would be half of the price of a Korean 2k hence the salt 2 being $800. I guarantee you didn’t pay nowhere close to that for a jp23 💯
Might need to fix 4:52 on the bottom where it says the Salt-2 is a Chinese amplifier instead of saying Korean 😅👍Still we all know its Korean because you say it is and in the beginning of this vid it says on the bottom the Sundown Salt-2 is Korean😁
Man that's messed up I just bought a JP23 v2 and called the other day to make sure and was told on Down4Sound Shop's customer phone line that the JP23 v2 was a KOREAN and not CHINESE amplifier. Then he uploads this video. I'm a loyal D4S fan, but really feel robbed on this one. Considering seeing if I can return the JP23 v2 and buy a JP33 instead.
Jp 23 v2 is made in china it says right on the box lol. 33 and up are Korean . Hooligan ko amps are Korean it says right on the box lol I own both amps the jp23v2 and hooligan ko 5k ? Now jug bought the cream of the crop Brazilian Powerus 10k. Yeah buddy lol big dummy. The hooligan ko don’t share same boards as jp they share the same boards as dd m series amps smallest Korean board footprints lol
Running Audio Legion Korean amps and wouldn’t go back if i could help it but run whats in your budget and what makes you happy. I was lucky to get my amps on closeout pricing for a pair of AL1600.1 and an AL110.4. Id try the JP amps though people seem to be happy with them.
I had a taramp 800.4 that amp didn't last 2 weeks. I couldn't even pick up radio stations on that amp then it went up in smoke almost burned my car up. I went with Rockville DB 45 and never had that problem again
Hey JP, I need some help. I've got a mechman 240, xspower d2700 under the hood, and 3 d4s lto's. How many runs of wire do I need to run from the alt to the lto's, and what amp fuses will I need? Also, would I be better off to actually run the wire off the battery to rear, or directly off alternator to the rear? I'm using 0ga ofc, fusing under hood as well as before and after lto's. May be overkill, but rather be well protected. Amps are sae3000.1 v1 (for now) running 2 x15v2 at 1 ohm, an audio control d4.800 and audio control acm4.300. I know fusing needed after lto's, I'm just not sure prior to lto's. Thank you for any info you can provide!
K, so he really didn't explain the difference. Korean is a half bridge style amp while Brazilian is a full bridge. Brazilian also tend to run much higher internal voltage then Korean. Chinese is just that Chinese they copy both Korean and Brazilian. It's not a knock it's an observation. Rockford, Kicker, and a couple other names use truly bespoke amp designs meaning nothing inside is like anything anyone else is really doing. You do get what you pay for but the Chinese market is starting to come up for the budget game folks. Just make sure the name behind it has some credibility. The JP 23 is a good amp for the price, is it a crescendo no does it do its job and make the juice yes.

China will build the amps as specd.bottom line.if vendor wants cheap amps at certain price point then the Chinese will oblige.lot if sundown subs are built in China as well.they are good
Yep, I got 30 Teampies coming and after the samples amps they sent, I couldnt be happier. They have stepped up their game, again it depends on who you ask! :D
I have two amps from D4S, a JP234 & a JP 84 bought on 2/24/22. One year, one month ago. Both have the same problem. The knobs to adjust the frequencies on both amps don't work correctly. I can't set either amp correctly. D4S won't back their warranty. I'm stuck with two worthless amps. After spending thousands, I do appreciate the company, just wish they would have better customer support. P.S. the amps were not touched since installed. Just did an upgrade and had to re-tune. That's how I found out. My Salt amp, is working just fine bought at the same time.
I have two jp 33 amps and both have the same problem. The rca output is virtually nothing. Adjusted the gain and settings and didn’t adjust nothing. Both of the have the same exact problem. I hooked my massive audio(Chinese) and ran them for 3 months no problems. I bought two skar audio rp3500.1d and a month with the same exact setup I had with the jp33 amps jo problems. I don’t make enough to buy amps at 2-3 times the cost of a reputable Chinese amp.
@@brianwaller7383, it sucks. But, I'm going to buy more Salt amps to replace these amps. In the long run, it will cost me less than replacing them again and again.
The amps come with a 1 year warranty. You said it was over 1 year when issue happened so I’m not sure where you are going with that. Regardless we would point you in the direction of getting them repaired yourself if anything
Just bought a jp23v1.5 two weeks ago to replace my skar rp1500.1. Never had a mins trouble with the skar ....just wanted a jp23v1.5....running an American bass xr 12 dual 2 ....thinking of eventually going to two 12 in subs ....what 2 subs would you suggest to pair with the jp23v1.5....have bug 3 kit and a 250amp alternator.
So just wondering, will Korean amps give the best power output for lower powered or factory alternators than the Chinese and Brazilian made amps? Also it says CHINESE next to price of Salt 2 vs JP23, just fyi....
Why would anybody buy a car audio amplifier just to abuse it? If people have the money to do that, then why not bring back American built amplifiers. 2 X 25 watts for $350-400. You can buy high output alternators for anything from a go kart to a Rolls Royce now in days. That was the major killer of amplifiers in the late 80s and through the 90s. It's all backwards now.
The person unwrapping tape in the background is extremely annoying and drowns out your monolog. Please let the guy take a break for the video recording...
