> 3 dayWhen I first got the package I could not believe how much heavier it was compared to other kits. The quality of the wires were no joke, these wires are strong and really deliver amazing power. Before I installed the Rockford kit I had some cheap wires running through car and it also sound a bit staticy, which did not make sense because it was getting good ground. But after replacing it with the Rockford kit there was a noticable difference in sound. It was louder and sounded more clear and it still had all the same settings. It is worth the buy and deal I got on it was incredible.

> 3 dayIm happy with the quality of the wiring but the fuse holder is pretty cheap and mine was supposed to come with a 100AMP fuse but my kit didnt have a fuse in it at all! I would have been fine with this kit without having a fuse if it was advertised as such but it says there is one included right on the front of the packaging, yet I didnt receive one. Its not pre-installed in the fuse holder or in the packaging.
