    • 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

Very flexible, high quality wire at a good price. One run of this is handling 10,000 watts from a 320amp alternator with no issues

    • Great wire
Size: 20 Feet Color: Blue
Accidentally ordered it too short. A simple extension via fuse block did the trick, and my voltage only dips to 13.8 full tilt. Great at accepting solder and holds nicely in fuse/distro blocks also.
