[QUOTE="SmartAsss, post: 7175719, member: 629857"] You need a high output alt for sure.. adding a second battery only makes your situation worse. now your alternator has to charge both batts and put out 1400w and run your vehicle. Thats a tall order for any factory alt. you can easy your electrical load by wiring your sub to a higher ohm if its DVC, and ditching the second battery. 1400w from a 13.5v system would require about 103 amps from your alt.. the car needs power too somewhere around 40 amps. you would need at least a 143 amp alt.
