poh22 said:Actually, caps aren't useless. With all the converting from AC to DC and back from the battery <-> alternator, you get pulses in the DC power that powers the amp. Caps do help for a steady flow of power, but they filter a lot. They get rid of the pulses in the power flow to the amp.. They may not be completely neccisary, but if you want more SQ, a cap would help that
wtf?! ac to dc? alternator to battery? NO! alternators are fully DC! there is NO conversion of DC to or from anything until you get inside the amplifier!
everything starts out DC in a vehicle, don't forget that.
but yes, there can be tiny pulses from the alternator, it's called alternator whine nothing else.
