Great wiring kit.
Crutchfield Customer Review (What's this?)
The Rockford Fosgate RFK4X wiring kit is definitely the kit to get. You can immediately tell that the power and grounding cables are good quality, high strand count which makes it flexible and easy to install. I used it to connect a Rockford Fosgate R1200-1D amplifier driving 2 Rockford Fosgate P2D2-12 subs. I installed this system in my 2008 Jeep Wrangler Sahara. I mounted the amp in the rear of the vehicle, the cable was perfect in length. I used all elements of this kit with the only exception being the speaker wire, since the subs are mounted in the rear I had plenty of wire left. I recommend retightening the power cable on both sides of the fuse holder. I also used dielectric grease on all my connections. Great kit, definitely delivering the power and a good signal to the amp.
Pros: High flexibility, easy to install.
