Re: Big 3 help?
You can follow the stock wiring with 1/0 high strand count copper cable. It will be fine. Are you needing more amperage because of a high power audio system or ? If so, you need an alternator upgrade, not a different battery. The stock alternator should be fine for up to 1000 watts RMS.
