Great!

The following review is for AK8, which is a part of the bundle you are viewing.

This is a great amp power kit! I've bought three of them for different cars that I have owned. The cables are excellent quality and easy to route.

Nice install kit!

The following review is for AK8, which is a part of the bundle you are viewing.

This is a quality kit with true 8 AWG wire. Has a high strand count and very flexible. The only con i have with the kit is they give you a ring terminal and spade for the ground wire but only a single ring terminal for the power wire but no spade to connect to your amp. I don't understand that but it's not a big deal. I would buy this again.

Great kit for the money

The following review is for AK8, which is a part of the bundle you are viewing.

This was the least expensive kit I could find to install my sub. It worked fine and had all the bits and pieces needed. Didn't really want blue wire but I wire-loomed everything anyway so it doesn't show up. Recommended!

RCA cables are thin and cheap. Other than that it is a good kit with everything you could need.
