right now i have the audiobahn A8002T amp running to audiobahn subs( i know audiobahn sucks) but everytime they hit my headlights and interior lights go dim, does this mean i need a cap. to regulate the power or is it my battery? any help would be great thanks.
yeah man, that mean's it's pulling too much power from your battery. I'd get an alternator - from what i know it could jack up your alternator if you keep pulling like that on your battery
no no no, get a High output alternator. a cap will just hinder your problems drawing more from the battery to charge it and still it will dim. you need 15amps every 100 watts of power. most stock alternators are 80amp youll want to go 140+ depending how many watts your using
