What it is

Complete copper wiring kit to install a mid-power amp the right way.

The Rockford Fosgate RFK4X is a complete 4-gauge amplifier installation kit. It includes 17 feet of 4 AWG power wire, 3 feet of 4 AWG ground wire, a Maxi fuse holder with 100-amp fuse, a 16-foot twisted-pair RCA cable, 30 feet of 16 AWG speaker wire and 20 feet of remote turn-on wire, plus connectors and hardware. The wire is 100% oxygen-free copper rather than copper-clad aluminum. A clean, safe way to wire a mid-power amplifier for speakers or a sub.

Pickup is at the Carson shop. Call to confirm it is on the wall before you drive.

Guides and comparisons

  • Car Amplifier Buying Guide: Picking the Right Amp for Your CarThe right amp depends on three things: what radio you have, what you want to power, and how much room you can give up. Tell us those and we can usually narrow it to two or three amps in a few minutes. Here is how we walk people through it at the counter.
  • Amp Wiring Kits Compared: 8-Gauge, 4-Gauge and 1/0-Gauge from Stinger, Kicker and Rockford FosgatePick the Stinger SK4281 8-gauge kit for a compact or lower-power amp. For most single amps up to the mid-power range, pick a 4-gauge kit: the Stinger SK4641 or SK4241, the Kicker 46CK4 with an RCA cable, or the Rockford Fosgate RFK4X with oxygen-free copper wire, a 100 A fuse and a 16-foot RCA cable. For big mono amps and multi-amp builds, step up to the Stinger SK4201 1/0-gauge kit. We match the gauge and fuse to your amp before the install.
