I have done a search on the forum about a question on how much power wire i would need for the batter to the alternator on the big 3 upgrade. All i come across is post about how to do the upgrade and not how much you need and would like to know how much power wire i need so i can order me some wire online..

 

IMO, waste of time, buy YMMV. Any decent auto parts store should have a selection of spooled wire you can pick from, as well as the necessary connectors, heat shrink tubing, crimp tool, etc. Or, Amazon . . .

 

Measure it? Depends how you are routing it. Get 0 gauge.

 

if your not putting hard core audio its not needed

if you are buy a 50 FT spool , enough for the amps, and the big 3
