Those little things...
Crutchfield Customer Review (What's this?)
This is a great kit with everything you need to power you new amp. The quality of the materials is great. The packaging is simple and convenient. The wire is nice and heavy, but still VERY FLEXIBLE. The grommet in the fuse block is not large enough to fit the insulated wire. It's an obvious oversight by the designers, and is the only reason I'm giving 4 instead of 5 stars. Otherwise it's a perfect kit.
Pros: great materials, complete and convenient, easy to use
Cons: a little pricey, fuse block grommets are too small.
