id scrap the 4ga for the big 3 and use 0ga.

I already have the 4awg...

regarding the fuse, I already put a AGU fuse holder, and apparently the bigger fuse you can get in that type is 60amp... does that mean i have to get an AFS fuse and holder???

thanks...

Go with ANL style fuses. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
