If you have the factory 2.5 in it and no major stereo installed, 2 gauge is the smallest I'd go. Personally, I ran 1/0 welding cable from the trunk and haven't had a problem yet. Just make sure you get a good ground from the battery to the body and you should be fine with 2.

I would recommend against 4 gauge though.

I'll put holes in him!!
