alright well i feel retarded for asking but whatever. I'm gonna put a g31 in the back but a few wiring options come to mind. Do i run 1/0 straight from the alt to the second battery, or rather from the starting battery + to the second battery??
also for grounding do i use another run of 1/0 from the second battery - to the starting batt -? or can I ground to chassis under the trunk?
