battery relocation
 

I know, I know, its been discussed to death. but I want to ask which gauge is better i'm going with 4 but some are saying 0-2 is better. guys out there with this experience please share your input.

On my relocation I used 0 but I think it was a mistake. 4 has more than enough current carrying capabilities and is a lot easier to route.

i used 4 and i haven't had any problems

I used some free 4 and it works perfectly.
