- How to charge, how to install, and how to use a Car Audio Capacitor. In this video Allyn and Brendan go over everything you need to know about capacitors.
Many don't realize that your capacitor can be damaged if connected directly to the car's bettery. Thats what the charging tool is for, it allows the capacitor to slowly charge from zero volts up to match the battery's voltage.
Most of you should know how to install and wire an amplifier, but what about when you add a capacitor into the mix...? In this video we also go over how you connect the power and ground wires from the battery to the capacitor and to your amp.
Finally, one of the little-known uses for capacitors, noise filtering. Capacitors naturally absorb AC noise, so if your car stereo has engine noise that you just can't seem to get rid of after hours of troubleshooting, adding a cap might just solve your problem.

The sound effects where spot on thanks solved one of my few problems. Will make sure I throw that ground down before the power. Appreciate it guys.
You guy's did so well... Very clean and esay to understand.
To watcher... Take note to plug de capacitor closer than possible to the amp... Then else the cap will only used as a filter.....
Very helpful so thanks for posting. I think it would’ve been better to explain the benefits and use of a capacitor in the beginning versus the end, but I finally understood.
First thank you for the info. It was a great way to show how to hook a capacitor up to a sound system with the car board example, it mainly help because you can see everything on one area and I was able to transfer that example into my car and it work perfectly,thanks again.
Well guys, thank you so much for truly clearing up any misconceptions about why a cap should be used, my only question would be then if a half farad cap cleared up the alt noise then why are there such large caps and cap banks on the market if they're mainly for filtering alternator noise? And the nvx looks identical to the pyle 5 farad except it has the terminal block (very nice) and the smoked plexi.
Great video! Very informative! I did not know about the filtration aspect of capacitors definitely going to install a cap to my system. Thanks!
Table car is awesome! Nice to see it spread out
Thank you guys that was awesome and your table is amazing.
That was an okay video guys thank you for the information, but my question remains, can I use a battery trickle charger to charge my 10 farad capacitor
I was waiting of these video
I bought this same Cap. Charged it per the instructions. The volt meter on the cap turned off. Then it came back on. Now it’s off again. Everything works. System sounds great. Headlights in my 2019 Tundra don’t dim. So what’s wrong with the cap?? Did I do something wrong? Or is it just an expensive distribution block now?
Hey guys - thanks for the video. In the process of upgrading the sound system in my truck DYI style and basically have no experience or knowledge. So I am learning as I go. Next subject is how to tune the system and set filters to the different speakers so they get a clean freq signal...
anyway...I just bought a T-Spec V8 3.0 cap and it didnt come with the resistor bulb. So I have 2 questions for you;
1. What kind of charging tool is that and do you know where I can buy it?
2. Can I use my automotive battery charger as a power source for the initial charge vs hooking up to my truck battery?
Thanks for your help and for posting the video. And the table car IS SWEET! I am going to scour CL and the web and see if I can find a good deal on one!
Caps are great DC current filters. Good info here.
Thanks for uploading this video. I just received my Stinger 5-Farad Capacitor and was searching high and low for the charging bulb that used to come with caps. Even the directions didn’t mention what the little circuit board was for! Do you have Stinger’s ear to mention updating their instruction booklet?
Thanks 👍 you answered All my issues
I totally dig the table car, I wouldn't recommend driving it at high speeds. My question is, I don't exactly have a voltage issue. I do know that I'm running 1000 w rms on a stock alternator and a single battery in a 2019 Kia. I'm hoping this will reduce the risk of killing my alternator and battery, but if nothing else I'd like to Know if it would potentially draw any more power than I'm already taking
Awesome video.
Great video and instructions
like the facts, Great job!
Table car looks siick!! but it looks like its mad out of wood, so a metal bar where the drill bits are to close the loop and actually show us how the devices look like in use would be better and a more realistic setup, perhaps ending the vid with a preformance of the decice, other than that, keep doing what you guys are doing, I learned a lot!!
Thanks Guys you’re amazing great video helpful for my installation
Great video, i have same problem. Mine is strange though. I just moved from Los Angeles to Chicago and have a 1500 watt amp on the internal speakers and a 2k watt pushing 2 12"'s. all was good in LA but after 1 month of being here my sound started dropping out. I thought it was my battery but after swapping out 8 batteries in 12 months i started watching you tube videos and realized it's my Alternator. I bought a 250 volt alternator and the first day i was out Banging and all was good then on my way to work 2 days later back to the same, sound dropping out with that fuzzy tone like a battery power3ed boom box dying on you. This weekend i am upgrading to a big 3 - if that doesn't fix it where else do i look for a fix. I cant believe switching cities would cause the issue. I get that i don't drive as fast here because this place is CROWDED and traffic is a B!
Need help. i have a 12v battery and a 3.0f cap. I'm running a 1200 sundown amp which needs around 14.5v to function properly. my alt puts out around 15v. Here's my question, my cap came with a test light rather than a resistor, so when i pre-charge my cap it's only at 12v. So should i attempt to charge my cap with the test light and the engine running so it's at a higher voltage??? Basically how do i pre-charge my cap into the 14s to properly supply my power hungry sundown amp? Or should a pre-charge of 12v be sufficient to prime the cap? With no cap amp is cutting out at high volume due to voltage drops.
can two amps be wire to the positive terminal on the capacitor is doing this step safe will it drop voltage ?
I have a 2000 watt inverter will this work for when I have a high current pull to help buffer the surge from the battery? If so should it be in parallel or series with the battery?
Running a 1000rms amp in a 04 chevy diesel so it already has two batteries in the engine bay. Would you guys recommend another battery for the amp or just a capacitor and or bigger alternator? Thank you
I watch this channel for comedy purposes. First they say put the Cap anywhere you want,... then they say put as close to the amp as possible. The second is the CORRECT way as a Cap discharges instantly and you dont want to lose any of the basically useless charge. Put in a second battery and an isolater instead of a cap. And do the BIG THREE, your car will thank you
Allen, I am building a 02 Chevy Tahoe. I just put the stereo system in it. Now it has a pioneer AVIC 5200 nex double din head unit, each door has a 6.5” speaker and a 1” tweeter with a crossover that has 3 settings +3db,0db,-3db.i have no idea what sounds better yet. Haven’t messed with them. They are Polk audio component sets DXI6501. I have a new Rockford Fosgate prime 300.4 4channel amp running the component sets. It has 2 sets of rca’s front and rear hooked up to it off the deck. For the bass I have a 18” custom built sub that I had running off my old ass db1000.1 Punch amp. I had stupid ass alternator noise! It made me loose my mind trying to find it. I changed out the deck, new RCA’S new grounds straight to the clean frame. I even built a complete new wiring harness from the fuse box to the deck and didn’t use any factory wire. Got it all done and turned it on and it was gone. Next morning I hopped in to head to work, fired up the truck and there it was loud as ever!! I almost blew a gasket! My db1000 was makin a ton of noise also ,so I gave it about 4 hammer fist hits and that quit that but now it has the power of a 100 watt amp so I fucked it up somehow. So I bought a new amp a massive audio N4 claims 2000rms. I seriously doubt that.... but brah,,,,,,, The hum is still there as soon as you turn the key on but only for a few seconds then gone. What the fuck it it!!!! I just picked up the 10 fared hybrid capacitor , same brand as in this video. Got it off a friend for 40 bucks. Fosgate sells the same exsact one but says there logo and it’s like 500! So I have that to put in and I’m going to switch from 4 gauge wire to 0awg wire. My friend also has a huge kinetic battery he’s going to hook me up with. For like 125 bucks so I’m hoping the cap will get rid of it. I have been messing with audio for like 20 years so I know better then to run the rcas next to the power and all that. I think part of the hum is coming off the alternator and thru the firewall so I might Change it also. If you or anyone has any ideas throw them my way. I have not ground the rca to the radio basket. I think that’s ghetto so not doing that . That’s part of the reason I said f it and bought a new deck in the first place.
I have a question does it matter how many farads the cap is rated for I have a 1000w max amp and about to install a 5 farad cap. Will it be ok to use?
Thanks for the video I’m having a lot of feedback noise or whining noise every time I install a capacitor this is the second one I have installed brand new same noise if I bypass the capacitor no noise at all can you help.?
By the way I am running to separate ground wires
If you buy a second hand cap do you still need to slow charge it if so where do you buy the slow charger from
So that means besides supplying power to the amps I can also set up a relay for the remote turn from the + of the capacitor! I watced vid this to get an idea of the power distribution from it. Thanks!
I have a 4 farad cap, I am charging it but it was a over night charge and still it has not hit the full charge. I use a DMM on a 20 v and test it and still it is only at about 7.56 v. I’m using the resistor that it was supplied with. Am I doing something wrong???
4:50 it'll turn off at 12 volts huh
🤣👏

I think the table car needs to go on tour to some shows!
hay! can you address any issues with over using or under using capacitors? ie. too big of a cap hindering amps being released to the amp. is this a myth? any input?
How did you guys make the grounding table? I have been trying to figure it out for the longest time. I ended up buying a 30v 10amp variable power supply. But a car table would be AMAZING and would make an awesome conversation piece
Hi sonic Electronics
My stinger 5 farad hybrid capacitor has voltage adjust knob. How to adjust that voltage knob ?
Thanks
My car goes into storage for winter, any suggestions on keeping the capacitor heathy during storage..Thanks!
If not connected, I saw the voltage slowly going down. Does it go all the way to 0 and have to charge with the charging tool again ? Or once installed it holds voltage
So if it doesnt have a distribution blick built into the capasitor, i could stack the positives together? And no harm will be done?
I don't know but sometimes a cap works because I had a mono amp that was going in protective mode , even after big three and audio battery upgrade ! so I got a cap and the amp don't even get warm anymore
I recently installed a fosgate rfc 1 single farard cap and this cap has no lcd display included , how dose one go about obtaining a lcd voltage readout and installing it??
Wow too good bro
Can i use my 2 grounds from the capacitor and the amp get it from the car instead of running a new wire to the negative of the batterie
hey i had not used my cap for one year and now when i connect it to the battery directly the voltage indicator does not light up
Thank you sooo much for this video! I had my battery die and so did the capacitor. So after replacing my battery with a optima battery. After 9 years of the capacitor being installed it had never died completely until now. I had total brain fart of how to charge it. Thanks again!
hey guys really like all the videos you guys put out the cap that you are using is it one of the top of the line or one of the 30.00 dollar ones, also im intrested in putting a cap on my motorcycle i am limited in space, i do have bags wondering how or if anything will it benefit me in installing one,going back the cap shown in vid is it 10.5 in tall.hmm!!!
Do you have the link where I can purchase the 4 wire resistor capacitor charging circuit? Thanks
Now that’s a good capacitor Right There
It dropped sooo slow, I saw that. Planet Audio Cap discharge so fast! A water bottle would work better.
I LOVE BASS AND CRYPTOCURANCY
So i have a soundstream AR1.8000D just for bass and i don't know what size fuse should i be using because the manual doesn't say. and i have a 1 fared stiffening capacitor and a other boss 16000 for my mids do i need a bigger alternator for this setup
you say when it drops under 12v the display turns off yet in the video it is still on?
+Just Trickky I was curious about that myself. Seems the microprocessor in this cap turns off when LED activity stops rather than a particular voltage is reached. If they had actually connected the cap to the battery, the LED readout would have stabilized to battery voltage and turned off.
do some bench testing and installs with some DC Audio equipment
I did the big three... I upgraded my alternator... i have a second battery... I drop the bass in the mix, my voltage meter on my truck says around 12-13v and my lights dim... I ordered a 3 farad cap and im hoping it will solve the issue... is there anything else i should revisit. Like Grounding or something...
+Bully ThaKidd If you did all those upgrades and you're still getting dimming then yes, absolutely go through and check all your grounds. Sounds like you could be losing some voltage to a bad connection somewhere.
Specifically the ground cable from your battery to the chassis, it should be two wires of greater or equal gauge to the ones coming off the positive terminal. Also make sure the battery terminals and connectors are clean for both positive and negative. The grounding to your amp is probably fine. Since you upgraded your alternator, you may also want to replace the cable going from the alt to the battery with a thicker gauge, but that wire isn't a fix for your problem, it's just recommended as a matter of cause. Unless of course they dim over time, not just when the beats drop. In that case you should definitely suspect the alternator wire.
So ur saying I have to upgrade my altenator to stop my head lights from dimming?
Switch to led headlight bulbs
Very helpfull but is it possible to install two off these capsitors.
If the cap is bad will static sound come through the speakers?
mine does have a input and output clearly marked as. but is it the same if it just comes with a resistor?
Does it matter via compasitor if your using loc28L for stock stero on a 2018 nissan sentra
Great presentation learned a lot. I have a question I am building a buggy and will be installing lights with delays. I like to use a capacitor or two to power my lights and possibly other electronic. Can this be done,? I would like to have the power when needed to power like head lights running lights, fog lights. Is a capacitor just for boosting amplifiers or they can be used like for my project??? TY in advance.
Bernie Jimenez caps are not battery's. They only store a minimal about it power they are designed to let out that power in a split second when the stereos bass drops a hard note. If you charged a cap and hooked a light up to it it would shine full brightness for less than a second before you could see it quickly getting dimmer until dead about 5-10 seconds total depending on size of cap.
why is my capacitor nvx xcap10h throwing sparks every time i have one already connected and try connecting the positive or the negative.
Why the charging green light dont go off ? Have it connected 20 mins or more. Its a stinger 10 farad capacitor.. does it take longer to full charge ???
Can I install a JL Audio 300 watt r.m.s. mono amp. To a single JL 12" sub, in a Lexus hybrid? Will it destroy my electric battery? Breden and Allen, I love your cable car ground! ;)
Which capacitor rating is suitable for an SUV sound with:
-2 8k subs watts each on 6k mono block, and
-2 pairs of 6 by 9” speakers and 6” speakers on 8k watts 4 Chanel amp
Is it okay to charge without the fuse connected?
The table car is cool.A great idea.
I'm curious how they grounded the table for bench testing
You should of also showed how to charge it with a 12v mini bulb. That how I used to do it before I realized they were worthless lol
I'm trying to charge a 24v capacitor, I cannot just hook 2 12v's to it, add it will make a closed circuit and the 12s won't be able to handle a 24 load, correct? How can I charge it??
How do use that charger it when hooking up a fuse holder by the battery
I heard you guys say not to hook grounds together because it could cause a noise ground loop. I was under the impression you should always keep all grounds connected together. What up? OH yeah cool table car display!
The idea is to avoid ground connections longer than 18 inches as this could introduce noise interference.
nice table car bros I got a set of rims that would look badazz on there let me know if 4/100 or 4/114 would fit hondalove
In old school , they use a 30kohm resistor in series to charge or discharge safely a cap.
Hi...can i charge my car battery into my ac/dc charger converter without removing the amp.capacitor regularly? thanks hope you can help me thank you.
So i bought a used cap no tool i have a .5 amp battery tender will that b fine?
Nice car table
Hey guys I watch a lot of your videos. I need with hooking up a Loc to my 2016 ford fusion se. I can't find a 12volt wire for the Loc turn on and off. Can you help me ?
How to connect a capacitor with a remote??
I jump plug the same remote in my cap and my amp?? (Like a jump)
1st rule I learned is never hook up ground untiil your finished conecting positive, the reason for this is you accidentally touch a hot wire to any metal (ground) you get arc!! Connect all grounds last. Same as when installing a battery in your car!!
i just sold my car and kept my audio system.. quick question, do i need to re-use a resistor to install the capacitor in my NEW vehicle? or skip that step?
Whats the resistor use to activate the capacitor for a 2.5
Anna probly wouldn't hurt if you upgrade the horse power llil bit I think about add new supercharger or a gigantic fan either one
Do you have to run a separate power cable for the capacitor coming off the battery? Or can you just run 1 into the capacitor and then split it into the amplifier?
cap comes between your battery and amp on the same line
Can these be used for camping?
I am using a 4.5 farad VM as a filter for the cathode heater on a single ended triode amplifier that uses the 833-A vacuum tube, a monstrous tube that takes 10 volts at 10 Amperes just to heat the cathode. This is the only way I know how to get rid of the 120 Hz power supply ripple from the rectifier through a 0.1 Ohm dropping resistor.
You should make your table car function. Put a piece of metal on the bottom side so when you attach the grounds, you complete the circut.
I just noticed your WS6 tattoo. NIce
Would I still need to use a 40/80 amp fuse when coming from the battery to the capacitor?
Absolutely! The fuse from the battery is to protect the wire so that it doesn't burn down your vehicle.
Can I charge my Rockville 50 farad with my normal car battery charger?
I'm building a generator and I'm curious can I use this or another capacitor like this one to help maintain a charge of a car battery...
No.
So this cap won't help with dimming lights? Like soooo many other companies that produce audio equipment claim? It's just a noise filter right?
It s cold here where I live and my battery 🔋 completely died so I got a new battery so now every time I turn on my system but the capacitor is still off in my music is playing but when I turn off my vehicle these numbers start to popp up so am I doing something wrong or is it working properly
I have a Question my batteries 🔋 completely died in my truck so I got a new battery but before I get my new battery my capacitor completely died with no power so by me having a new battery do I I have to recharge of the capacitor or does the battery do it because every time I turn my car over the compressor is still off and the numbers that show up is L. Hi then it’s shows up hi with are other numbers so is that good or bad
I have a 900w amplifier and I'm having unwanted noise from the speakers. I'm thinking of buying a capacitor but wouldn't know which one to pick. Is a 2 farad a good choice?
Unwanted noise is usually hum from the power cables being too close to the signal cables. It has nothing to do with a capacitor and generally a 900w amplifier alone isn't enough to warrant a cap unless you have a failing battery, in which case you should get that taken care of first.
If you have power cables traveling on the same side of the car as your signal leads you should change that right away, you'll see a noticeable improvement. If not that then you may have a bad quality junction, splitter, or crappy RCA plugs/wires causing that problem. Test the resistance of the signal cables and see if any terminal is reading high relative to the others.
I installed a 1500w bass speaker in my car last week now at low revs the car seems jumpy/jerky would fitting one of these fix it?
Probably not. Maybe you need bigger wires, better alternator or better/ extra battery
could you connect 2 compacitor together
i have 2 kicker crv's in a ported box that i am pushing with a massive n4.. i have a massive 4 cap.. my problem is when i turn my stereo off i get this huge rumbling sound from my woofers.. im wondering if i should take the cap off.. what do y'all think?
Sounds like more of an amplifier/headunit problem than a capacitor problem to me. I don't know the details though, i guess it might be the low pass filter in the thing? They have coils to shape the sound characteristics and when power is cut off the coil's magnetic field collapses, causing a jolt of voltage... I don't think that'd be audible as a rumble though, so who knows.. Maybe a combination of caps and coils for a steeper drop off, but that's literally a shot in the dark as to what's causing that. I will stick with my original guess though, that it's not anything to do with your capacitor.
where is it possible to take the 4-wire circuit resistor capacitor charging ???
my lcd display isn't turning off its going down to 11.6 or 11.5 and stays on all night I did everything like u guys said any ideas what's going on?
If it's connected properly and stays on then it is discharging. If it is discharging it's experiencing s draw or you need a new battery. Do your amps switch off when your car turns off? Do you have a cellphone charger with an led that is always on?
I didnt use resistor or anything. Just ground from frame an power from battery... Didn't notice anything, how would I notice if something is wrong?
