how to charge capacitor?

[denracho]

i have a lightning audio cap and how to you change it? i have a charging kit on hand.. thanks

I always thoguht that it charged while your vehicle was on.

 

[denracho]

but it needs to have 12 volts before you install it.

 

[denracho]

but already charge it. thanks..

use a resistor, if you hook it directly with the cap fully discharged it shorts your electrical system

before this thread dies can i ask a question

some kid told me that bass caps are bad for your car. BS right?

 

[denracho]

yup. a cap will help you to not discharge your battery while hitting loud bass notes... i would say thats bs

I just figured I would putin my . Im no audio wiz.

 

[denracho]

that's coo...

Did you get it charged? It's easy? Once it's charged you wont have to charge it again

Yeah, all you get is a spark that will mar the caps terminal though.

 

[denracho]

if you charge the cap. you need to install it quickly because it discharge really fast.

i never heard of having to charge a cap before u put it in. I have an audiobahn 3 Farad cap and it didnt need charged.

 

[denracho]

i think it need to be charge bec it needs to have a 12 volt stored, when your bass hit a peak note, the amp borrows energy from cap.thats when you need to charge it. in your case 36 volts must be charged, 12 v per cap

you do realize when you don't charge them if they aren't already holding charge, power flows un-impeded through the cap creating a short? Charging a cap up to a certain voltage isn't going to insure it stays at that voltage, its always going to be at the voltage of your battery, it just works to oppose a change in voltage between the two devices.

 

[denracho]

we need to charge our cap before using it. i will short...

Well, Im not sure what to say. I didnt charge mine, and it keeps the voltage a lot more stable than it did....maybe I lucked out.
