Best kit money can buy

The following review is for XKIT44, which is a part of the bundle you are viewing.

This kit includes everything I needed for my 4-channel JL Audio amp. I love it. The look of the fuse holder is awesome and the braided cable protector is great under the hood too. The RCAs worked like a charm and I had plenty of speaker wire included. No complaints.

great

The following review is for XKIT44, which is a part of the bundle you are viewing.

Have not installed yet but it seems to be everything it claims to be. Did recomend itnto a friend but he didn't listen and spent way to much for a kitat a local best buy. Did a lot of research before I bought this kit and it looked like the best value for my hard earned money. Having not yet installed is why I didn't go all five stars. Soon it will be going into my 89 olds custom cruiser with 4 12s....

Awesome kit!!!

The following review is for XKIT44, which is a part of the bundle you are viewing.

This wiring kit is the best I've used so far. It bends very easy in tight places and this is the size wire that I actually paid for. Don't waste $ on cheaper brands...NVX is AWESOME!!!
