[QUOTE="hispls, post: 8750677, member: 614752"] Assuming you only rarely drive that car, I could see batteries not lasting well (unless you leave them on trickle charge when you're not driving regularly) and assuming you are just buying remanufactured parts store alternators which can be really hit or miss quality. Parts store cheap alternator is <100$ typically and you''ve probably been buying sub 100$ batteries too so yeah, life span is about right. Non AGM batteries will fail extremely quickly if you deep discharge them (like from leaving the car sit without a trickle charge all winter when you're not driving) then running your alternator into a dead and dying battery will put extra stress on that. Ohm's law states that P = IE and E = IR E - Voltage I - Current R - Resistance P = Power Your amp is a constant voltage source so doubling resistance halves the current and therefore power. Sure, a 5 or 6 channel amp would be great provided you have some fronts that can hang with more power, but there's absolutely no reason your audio equipment is the cause of this issue, more likely just the canary in the coal mine that's letting you spot it now.
