a cap usually won't solve your dimming problem because the larger gauge wire running your amps will take priority over the smaller gauge wires running your lights. unless you get a massave cap, i don't think this is your solution.

o, I guess what i heard about a cap was that it would just give more power when it needs it most, u know a " power stiffener". so do i need a higher power alt. or somethin along those lines?

what ya need is a bigger alternator, or less volume. :-)

here's more about caps and alternators and what they really do for you:

hey glass, for clarification, ur link states if the car motor is off, a cap put a greater load on the alternator because it has an extra item to charge thus causing even more damage to the the alt. does the cap cause any damage to the alt if u listen to ur system only with the engine on?
