Currently have some 4guage wire from alternator to battery. (Its in the trunk)
Now, since I have AD-freaking-D, I was looking at what size gauge I should have to carry 200amps (max alternator load).
Using this calculator

I should step up to an almost 1/0 size if I want to minimize voltage drop, but I think I would use a 0 gauge. Would go from a calculated drop of 1.25 to .611, which I think would help across the board.
Only downside I see is addition of weight, thoughts? Comments? Concerns?
