How To Charge and Install a Capacitor | Car Audio Q&A

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.

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.

[@jedcasto7687]

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

[@israeljimenez9500]

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.

[@CBALLZ666]

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?

[@JustTrickky]

you say when it drops under 12v the display turns off yet in the video it is still on?

[@j_ro]

+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.

[@PROATV13rb]

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.

[@MikeSmith-gv2pq]

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!!

[@devintackett7048]

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

[@Snow101Bunny]

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.

[@FMATTV1986]

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

[@666hobart]

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.

[@jean-francoiscyr1013]

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.....

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???

[@Highqman1974]

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

[@markrailey8000]

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?

[@dawgzfan27]

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.

[@Jinkins100]

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

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!

[@2011wideglide]

Question. Just like yours in this video once I disconnected the relay to charge the cap the cap started discharging as seen in your video with the lcd screen. Then eventually it says low. Does that mean it is discharged? I don’t want to see the cap discharging my battery once connected nor do I want to hurt the cap. I did put a meager across the terminals and it reads nothing after sitting and it says low.

[@roamsweethome4895]

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?

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.

[@jamesf9610]

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.

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

[@BarHRanch]

You mentioned you may need to upgrade your alternator. At what point do you know that is what you need to do?

[@jamisonw.327]

When running at a significantly high volume eventually causes the amp/head unit to go into power protect mode. This means that your battery is draining and your alternator isn't able to give it enough power to maintain equilibrium. Before you do that though, first check that your main grounding cable from your negative battery terminal is good and beefy, and that it's making good contact with the chassis. Also consider replacing your battery first, as this could solve your problems as well.

[@mikegonzales3314]

I got an 8.8 Compacitor when I go to charge it, it takes longer then it should? I’m stumped on it and don’t know what to do

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 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.

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?

[@arvivirash5561]

cap comes between your battery and amp on the same line

[@quisinyjuandel2037]

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?

[@jamisonw.327]

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.

[@BullyThaKidd]

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...

[@SonicElectronix]

+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.

[@jamisonw.327]

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.

[@jamisonw.327]

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.

[@marsrover001]

I love how the cap slowly discharges through the video back down to 0. Thereby making that slow initial charge completely useless.

[@chrisw1462]

Yeah.. No way a real decent capacitor would do that. Either the cap is bad (leakage) or that voltmeter REALLY sucks the mA's.

Any car 12 volt light will work. Hook up one wire from the light to the batter positive and the other wire from the light into the cap positive. The charging pc that they come with is nothing more than a resistor not letting the full 12 volts thru at one time. When the light goes completely out the cap is charged.

I then touch the other end of the resistor to positive battery power and after a few seconds my LED reads "Lo"> IT stays like that. I get not charging digital numbers counting. What would cause "Lo". I know for sure that my ground is good with paint sanded away.

maybe your resistor value is to little and is consuming the voltage himself~.

Two things. Make sure that the car is on while you're doing this, and also make double sure you're not switching the positive and negative around on the top of the cap.
