This is in fact a 2 GA wire, not 0 ga, so don't be fooled. The shielding is massive (0 GA), but the wire (2 GA) is not. It is flexible, which makes it easy to use. The ground wire wasn't long enough, but I made it work and the distro fuse block wasn't set up for 2 ga wire (will only accept 8, or 4 GA if you cut a few strands out of the bunch). Other than that, I was able to set up four amps off this kit (14,400W (two 5000.1, 2400.2, and 2000.4), just had to buy a different distro fuse block. It was a great deal for the price. The power wire came with massive lugs which was nice (didn't have to go hunt them down). The RCA wire was way longer than I needed, but each person needs are different. Would suggest this for anyone looking to get a lot of current a long distance. Carries a lot of power. Was able to tie all 6 additional batteries together, and still run wire to the amps (second alt already set up).
