yeah capacitors are pretty worthless. the better thing to do would be to upgrade what is called the big 3. that is upgrading the wire from the battery pos to the alternator pos, the battery neg to the chassis, and the chassis to the engine block.

but for the amount of power that youre running, yo dont really need to do either. i have 2 amps in my car and one of them is pushing over 600 watts to my sub and the other is pushing 200 watts to my comps and i have no problems with dimming or anything.
