I have a 2006 Dodge Magnum and I am on my third starting battery in 3 months. Just got a new battery thru warranty and doubt they will give me another if I fry this one. My system consists of a Pioneer dvd head unit, all speakers replaced with Memphis coaxial's running off of factory amplifier. Sub stage is an Skar EVL 15 powered by a Skar RP1500. Electrical is a 160 amp Carquest alternator (recently replaced) powering a Batteries Plus X2 Power group 94 (made by Northstar) starting battery and a XS Power XP750 wired together powering the amp. Big three is done including 1/0 Sky High CCA from the alternator to the back of the car where the battery is. Car also already has a 2 gauge cable ran from the alt to the battery stock since it's such a long run. I have fried two of the X2 Power batteries somehow but the small XS battery hasn't been affected. Had both failed batteries checked and the voltage would be good but the cca would be so low it wouldn't start the car unless hooked to the xs battery. At full tilt the voltage will drop to around 12.2 and at night the lights will dim slightly. Can't see why my current electrical can't keep up with this small system. Anybody have an idea of what is going on? I have checked and rechecked all connections and grounds and am at a loss for what to do next. I have ran more powerful setups on pretty much stock electrical in other cars and have never had this problem. Sorry for the longwinded post and thanks for any help
