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....

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!!!
