KnuKonceptz Kolossus 4 Gauge OFC Amplifier Installation Kit

Fantastic quality product! If I ever need more this brand is boss.

These are some real nice wires. True 4 gauge power and ground. The wires are nice and super flexible for the gauge size.

This kit is priced great and has excellent quality. I have done several hundred installs and the power and ground cables are the most flexible Ive used and have impressed me to the point of picking up this brand to use exclusively in my shop. Sorry stinger

Decent wiring kit for the money, but Ive used better.

Great price for it being oxygen free copper. Very flexible too, and heavy. I used my 4ga kit for the first time about to install a subwoofer on my Chevy truck. The fuse is small enough to stay out of sight, and the terminals fit just right. I will definitely buy again, and Amazon prime did a great job delivering promptly. After two years, the wires are still doing their job conducting electricity. The only item I didnt use was the rca cable. I used the factory radio and the amplifier I have can tap directly into the factory system. The rca cable seems to have a third wire that might be used for the remote turn-on, but it looks to be very thin. Obviously you just need a signal to turn an amplifier on, so it might be enough to do the job, but I have t used it yet; its in a box in the garage. Cant wait till my next project!

Best wire I have ever used, I ordered some cheaper wire that never made it to me, and I’m very happy I went for this quality. It’s perfect for the install I’m doing. OFC is fantastic.

Quality wiring for doing amp installs. The only thing I dont like is the ground wire could be a foot or 2 longer and the remote wire did not totally wrap from the trunk under the trim to behind the glove box and to the radio. It was short by 2 foot but its no biggy.

I researched this to death and am 100% confident that this kit is the best low-cost wiring kit on the market. A breeze to install and after running it for a good 5-6 months, I have had zero issues with it.

The power wire is not ofc. This kit is far too expensive to be using garbage wire

have not did install yet but if what ive seen so far of this product its a great indication of what the overall performance will be and ill write a result after , all wires are very heavy duty just like photos or better and i was sold on them and had faith so purchased 2 sets for both of my vehicles !!
