I have 2ga Tiff wire, 2ga crimp rings and a 2ga-0ga ANL inline fuse holder. I don't believe I have a 125 amp ANL fuse, I know I have a 100 amp fuse and maybe a 150 amp fuse but I will check tonight.
Tiff used to be Streetwires high end brand. I have a 125ft spool (it's a purplish color). Look here; Tiff 2ga wire, it's the second wire from the right.
