Big 3 upgrades

[05wh250]

I'm looking to upgrade the wiring from my alternators. Im also looking at upgrading and adding a few grounds. Wondering what you guys are using for fuses from the alternators and if your upgrading the connections at the battery's?

I'm curious about this as well. Also wanting to add a third battery on the frame for accessories

I never did the big 3 on my sd, just for the fact these trucks already have decent sized wire, BUT, the alternator wire is a joke. I had a 270 amp alt, sundown 3000d (3000 rms watts) and 1/0 ran from the drivers side battery to the amp. Really never had any problems.

I built my own from scratch but the idea came from here.

Thanks for the reply. I would like to upgrade the alternator wiring, was just unsure of the fuse size to use, mine has the stock dual alternators on it.
