In general the kit is ok. The amplifier cables are not solid copper, but a bundle of thin copper wires, which makes crimping difficult. The fuse box is oversized. There was no place I could logically mount it next to the battery in my 370z. I had to go to my local audio store and buy a different fuse and fuse holder. The best quality is speaker wire. They are rubber shielded on the inside and look very durable.
