So later on I'm going to upgrade. Im going to need a new battery and alt. my question is what battery do I need for my setup? I'm going to be running 1 hifonics zeus 1500.1 at 1000 watts rms and a hifonics Zeus 600.4 (75 watts rms each) for a total of about 1500 watts rms. with the fans for amp rack and some LEDs. (I know they won't be that much amps but I'm rounding up to make it easy) so I need a battery for that and my car is a 1999 dodge durango 5.9l with a stock 117 amp alternator. What battery will be best and what size alternator(probably mechman) will be best?
