Rockford RFK4X 4 AWG Complete Amplifier Install Kit

The cables were just long enough to go from my head unit to the amp under my backseat (2006 silverado crew cab)

Worked well

Awesome cable! Fast shipping !!

Same old kit from years ago.... It works...

Gotta have this for reliable a reliable sound system. Has every thing you need to a heavy duty install.

Great buy. These were obviously the proper gauge unlike the last wire set I had. They are powering my P500-bd very nicely. Now only if I could say the same for my alternator :(. Thank you Rockford your products put the boom boom in my ride.

Easy installation and superb product

When I first got the package I could not believe how much heavier it was compared to other kits. The quality of the wires were no joke, these wires are strong and really deliver amazing power. Before I installed the Rockford kit I had some cheap wires running through car and it also sound a bit staticy, which did not make sense because it was getting good ground. But after replacing it with the Rockford kit there was a noticable difference in sound. It was louder and sounded more clear and it still had all the same settings. It is worth the buy and deal I got on it was incredible.

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

Works great
