Rockford RFK4X 4 AWG Complete Amplifier Install Kit

This is expensive but!!! You will not be disappointed. Dont skimp for some copper clad aluminum wiring that has insulation thicker than your calves. You will receive a quality product that will give your amplifier the consistent voltage to drive solid bass and unmuddled highs that is was designed to do. I am very happy and have learned that the install and quality of supporting component such as wiring will give a balanced sound quality driven install that you will be proud of.

I always love the quality with Rockford, length was good, and good quality cables help performance. Just make sure to ground everything correctly!

package was all busted up on arrival packaged up poorly with paper.

Great quality wiring helps to provide great quality sound. I would definitely recommend this product to anyone

Love how it’s just a plug and play kit with no crimping needed. Everything’s all good to go

This kit is perfect! Had everything needed to wire my 1200 watt amp and 2x 10” subs. The wire quality is top notch and everything worked great. I’d definitely buy again!

Quality wiring for a quality sound system, dont waste your money on the other brand of wiring, its cheap and itll do you no good in the long run. I have two sets of this wiring, (4 AWG, and 8AWG). One is for my subwoofer amplifier, and the other is for my Speaker amplifier. The thing I like about it is that on the back of the package, it says that it is true gauge wiring and it explains how, saying that other brands simply put more rubber coating around the wire to make it seem thicker with the jacket. This is TRUE gauge wiring. BUY IT.

I have used this amp kit in two different vehicles and on multiple amps, and I have no complaints with it. It is true 4 Guage (NOT including the insulation) high quality copper wire. The speaker wire is only 16 guage, but it is also good quality.

The kit includes everything needed to install your amplifier with abundant cable lengths. Recommend looking up how to cut the thick power and ground wires. Not sure if there is a good tool for this. I used a sharp knife and pair of dykes. Made a mess of the many copper strand wire the first few times.

Well made but expensive
