I have always been a big fan of rockford and usually like to stick to just a few brands. Had this amp kit on my last civic hooked up to a rockford P1000-1D amp and this kit delivered the power! This is a true 4-gauge amp kit unlike some of the other kits on the market. Will never buy a different brand amp kit again!

It was a good kit, I did have a couple problems figuring out the fuse block (it was nothing that I had seen before) but I figured it out. Other than that- it was a good kit at a great price.

I bought this cable knowing it was a great cable. I've been told it doesn't get better than this. I have it connect to my 1500 Rockford Fosgate amp and 2 12" L7 square kickers. It sounds great and hear nothing but bass coming from my speakers. Must buy!

this kit was perfect for my setup. the included 100 amp fuse was just the right size for my amp. also the extra strands of wire compared to regular cable made it able for me to not need a capacitor in my system. The fuse block could be a little farther from the end lug, and the lugs would be a lot better if they were soldered on ins ted of crimped but its perfect for the price.
