Right now I have a 900 CCA Yellowtop in the box of my truck, approx 15ft of wire. The charging wire is only ~8 gauge and before I put my new amp in(1500w rms) I would like to upgrade that wire.
What size wire should I be putting in there and what should I fuse it at? MB Quart is internally fused @2x70amp. I'm gonna be running 4x100w for front stage and 1x1500w on substage. Planning on doing the big 3 upgrade at the same time... Also what size wire should I be using for that? 1/0?
