hello guys. im really stumped on how to fix this light dimming/voltage drop i get from my truck. its a 2000 chevy silverado 1500 with the 5.3l v8. i only have 4 10 in p1s which is only 600 watts rms. i have two RF 201s amps for the subs and one RF prime r150-2 for the front door speakers. ive done the big 3 with 0 gauge wire and have a DC power 190 amp alternator. i thought the alternator would fix the problem but it hasnt seemed to do much. the volts definitely jump right back up though. i think there may be something wrong in the system that is drawing too much power? also when i both my windows up at the same time i get a LARGE drop in volts that dim my lights. please help me! i thought my stock alt would be able to handle these subs but clearly not.
