Product details
Power, ground, and signal in one kit
RFK8I covers the main amp power run and the low-level signal path. You get 17 feet of 8 AWG (8.36 mm²) power cable with 735 strands, 3 feet of matching ground cable, a 16-foot twisted-pair RCA, and 20 feet of remote wire. An AGU fuse holder ships with the kit so the battery feed can be fused near the power source.

Full-spec copper and hardware
Rockford Fosgate rates the cable as 100% pure crystal oxygen-free copper (PC-OFC) that meets or exceeds AWG requirements under the CTA-2015 standard. Termination hardware is included for the power and ground ends. Match the kit’s 8 AWG size and fuse rating to your amplifier’s power-wire and fuse guidance before you cut or crimp.
