X-Treme Series XK4Z 4-Gauge s Amplifier Installation Kit

Quality cable. Thick power wire with not too much plastic jacket. It's a good compromise of price and quality. Not the best out there but pretty good and at a great price. The only complaint if I have to find one would be with the crimp on connectors. They were slightly difficult to crimp on the wire however that would mostly be from lack of correct tools but a hammer seemed to do the trick when the pliers wouldn't. Conveniently the power cable had it already installed/crimped on. The power cable was also cut at 12" or so which is ideal but it would be nice to cut it to a desired or custom length suited to your vehicles needs around the battery. I've installed 4 different cable kits and I highly recommend this one. The knuconcepts brand was my second choice when I was shopping around Amazon and went with this one because it had the remote wire included. I believe the other brand had the remote on the rca but I would prefer a separate cable. The two brands are good and probably some of the best on Amazon and I would buy this one again.

This wiring kit had everything I needed to install my amp and more. The ground was a perfect length, I didn't even need to cut it. And the power cable was very thick; the copper wire is high quality and definitely reliable + a lot of insulation. The ends to connect to the battery and to the amp were perfect, and I love the gold color. This is a very high quality and CHEAP kit, I would definitely recommend it! True 4 gauge wire and everything you need. The only thing I thought was a pain in the ass was the installation of the fuse, it took almost an hour. But I don't think other kits have the power wire already cut for the fuse to be installed.

We bought this amp kit for the installation of an amplifier and some rather large subs in my sons car. The installation went smooth and it sounds great. The only issue that we ran into was the length of the ground cable, the car is an Altima and the cable is just a little too short. It connects but if the sub box moves at all in the trunk it will pull the ground cable off of the amplifier. That is our only complaint, the sound is clear, strong, awesome. We can always tell when he is coming home based on the thump, thump that we can hear from the inside of our home. Haha. I would definitely go with this kit again, it has been a good quality kit at a great price.

They kit is a great kit, my only complaint is the negative wire could have been alittle longer for my install, (so I could have used the factory bolt) but that was my fault for the placement I chose. The kit works great and my only real complaint would be that the power on wire and the RCA's were not made into one molded wire like most kits, but the power on wire is top quality.

Pretty general as far as install kits go I imagine. Better value and better quality than many. Everything worked out fine except for the extras I had to purchase. If you want good gold terminal connections for both positive and negative at the battery, a capacitor and the amp you need to get extra connectors. I had to find them online because I live in the middle of nowhere. I also ran an extra (18gague) power wire for my sub lights with the amp power cable which required a different grommet. However, the cables were all long enough, arrived as advertised and worked great.

This is a great wiring kit for only $30! It includes plenty of length for all of the wires, and they are all very high quality and are the thickness that is specified. My friend that helped me install my amp said that it was better than his kit that he got, and it was more expensive. I would recommend this wiring kit to anyone that is installing an amp!

Has everything you need to install. RCA cables are a bit cheep, I upgraded mine later and hear an improvement in sound. Other than the RCA cables the rest of the cables are good quality. Ground wire is very long, I was able to use excess on other projects I was working on.

I do like these cables a lot. I was excited to actually find a true 4 guage amp kit on Amazon. It seems that A LOT of these kits on Amazon are true 8 gauge claiming to be 4 guage. I do agree with a lot of the other reviewers with the fact the connectors are a little cheap/flimsy. This is actually a plus if you don't have the crimping tool that is required for the sturdier connectors. I was able to take needle nose pliers to the connector for ground to catch the ground wiring. I will probably upgrade all the connectors in the next few weeks. My Amp is a THUNDER500.1 and I have two 12" Terminator subwoofers. The sound is great. I feel that these products together will last a long time. Buy this kit!!
