Awesome product for the price
I was overall satisfied with everything in the kit. The wire was great quality and easy to run. I liked that it came with a plastic grommet for my firewall. I think the fuse was really nice and looks great under the hood. Just make sure you have a 4 gauge crimping tool which I did not have. I ended up crimping with some pliers and a hammer to tighten up the terminals.

Good kit for the $
Used this kit to install a 4 channel amp and had plenty of wire to do the job.

good amp kit
The amp kit works well. The installation was very easy. I had plenty of wire. For the power and ground wires I soldered on my own copper lugs. The only real drawback is that this kit is cca instead of ofc, but that is why it is so cheap.

excellent value
this had everything you need in it to do an amp install. I was impressed with the speaker wire as it was a heavy gauge wire. 14awg I think. it was listed to have 20ft of speaker wire in product description but had 65ft in package, (nice). all the wire was nice and flexible (easy to work with) unlike some cheaper wire I've seen or used that's real stiff. couldn't ask for anything more.....

Worked Perfect
Great price and fast shipping. It was all I needed to hook up my amp and composite speakers. Plenty of length on all can cables.

Really Good Quality!!
Got this wiring kit at a discount after purchasing together with amp, so ended up at around $37. Ive bought 4 gauge wiring kits before at local radio shop for the same price, but not the same quality at all! The power and ground wire are super flexible, great for passing through firewall and bending around tight corners. Great quality anl fuse, and was surprised to find 20 ft of equally good, thick, speaker wire, just enough to rewire my whole car! And loved the 4 twisted rca cables that make install a breeze, and helps keep everything looking neat and clean. Perfect for a 4 channel Amp Install.
