31-03-2025Im 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.

> 3 dayI originally purchased this wiring kit back in 2012 and was so impressed I ordered it a second time for my new vehicle. This is the complete kit and included all required wiring for a new setup. You wont be disappointed with this kit as the price and quality is spot on. Rockford Fosgate is a brand that speaks for itself when it comes to car audio. Best wiring kit you will find on Amazon and you wont find this quality kit for the price in stores anywhere.

> 3 dayWas very disappointed. I didn’t receive any Rockford Fosgate products. This looked like someone’s scraps from an install. The quality was a no name brand aluminum copper wire 6 or 8 awg. Promptly returned.
