I have a clarion 1500 and about 800 watts total for the other amps, a yellow top up front and 2 alpha cells 110 AH in the back supported with a singer 275 alt and im still dropping to the low 11's even when driving :/, i have soundquest 1/0 wire (which could be the problem) and I just got cadence 0 gauge, should I just make a double run or just replace the soundquest completely? What could be other possibilities because I've always had this problem but no matter what I change it still drops, the alt is perfectly fine but any suggestions?
