2x 4ga should be more than 1x 1/0. and i didn't fuse my big 3. the power wire (alt to batt) will be hot on both sides of the fuse (even if it's blown) so i don't see the point. preference really.

i'm really not sure what size the alt. is???, but i know its stock on an 03 f150

130a. I have 1/0 on mine, the same truck. 2x4 gauge is fine. Hell, 1x4 gauge would probably do.

I would go with 2x4gauge on a 130 amp.
