Got a question about my battery situation.vehicle is a 2000 2dr blazer. Plan on running 3-4 batts and 2 alts. Alts of course in the engine bay, 2 batts in the rear beside box, and one behind each front seat in the cargo doors. What would be the best way to hook it all up? Run all battery, amp, and alternator wires to on location (on the side of the box)? Any help is great.
