Many car audio fanatics will use a power capacitor as an alleged passive storage device to supply current to their amplifiers. Capacitors are advertised to act as a supplemental power supply between your car’s electrical and audio system. ... In fact, a bigger capacitor can lead to bigger problems. Bigger capacitors have longer charging times ...

It could be as simple as a bad capacitor. A first test might be to check for an audio signal at the input to the speaker relay. If there is signal almost as soon as you power it up, then trace back from the relay coil to see what type of circuitry is there.

I am running 2 Sony Xplode 12" subs, a 1000w amp running at about 800w RMS @ 2 ohms, and a 1 farad capacitor. Now my problem is, with the capacitor hooked up I cant hardly turn up my system at all, the volts go way down and my amp shuts off, (I'm guessing due to lack of power) with out the capacitor on it works ok.
Audiophile Grade Capacitors

The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to .001 uF. Above that value, polypropylene is the type of choice, with nearly the same qualities of dissipation factor (DF) and dielectric absorption (DA) as polystyrene (these are the two ...

ok, i dont know what these guys are saying exactly, so im just going to answer your question. capacitors don't really leak, like you said, they go bad, and very occasionally swell. your only way to test, is to put power into them, put a voltage meter on them, and see if they hold voltage. if they do, use them, if not, throw them away cause they are good for nothing. what …
