    • Amazing wire
Size: 20 Feet Color: Blue
I did have a hard time buying Lugs for it. I think I found some 3/0 lugs with 13mm ID but it was too big when crimped but luckily I bought a good crimper tool that has 4 different size settings and got it worked out. FYI you'll want to get their fuse block because no one else's will fit the Oversized wire. ... show more
