Description

Rockford Fosgate RFK4D is a complete 4 AWG dual-amp installation kit built for high-current car audio systems, featuring 100% PC-OFC copper conductors, mixed-gauge power/ground runs, and dual 4 AWG distribution blocks for clean, reliable wiring.

  • 4 AWG Power Wire: 17 feet of 4 AWG power conductor to deliver ample current to two amplifiers with lower voltage drop compared to thinner gauges.
  • 8 AWG Power Wire: 6 feet of 8 AWG power conductor for flexible routing where slightly lighter gauge is suitable or for secondary power paths.
  • 4 AWG Ground Wire: 3 feet of 4 AWG ground conductor to establish a solid chassis return and minimize ground noise.
  • 8 AWG Ground Wire: 6 feet of 8 AWG ground conductor for additional grounding options in a multi-amp install.
  • 16 AWG Speaker Wire: 30 feet of 16 AWG speaker wire to connect head unit or amps to front/rear speakers with adequate impedance for typical mid- to high-power setups.
  • (2) 16 ft Twisted Pair RCA's: Two 16-foot RCA interconnects provide signal transfer with reduced susceptibility to noise between source and amplifiers.
  • Maxi Fuse Holder and Fuse: Integrated fuse protection for the harness, helping safeguard equipment in the event of a fault.
  • (2) 4 AWG Distribution Blocks: Two distribution blocks to neatly split power to two amplifiers while keeping wiring organized and under proper gauge.
  • Remote Wire: 20 feet of remote turn-on wire to reliably wake up amplifiers in sync with the head unit.
  • 100 Amp Fuse: High-current fuse size suitable for protecting the installation against overloads in dual-amp configurations.
  • 100% Pure Crystal-Oxygen Free Copper (PC-OFC): Conductors crafted from PC-OFC copper for low resistance and durable, long-lasting performance.
  • Includes termination hardware: All necessary wire termination components are provided to ensure secure, reliable connections.
  • FULL spec cable: Cable meets or exceeds AWG requirements, ensuring consistent conductor sizing across the kit.
  • 1 Year Warranty: Manufacturer-backed coverage for peace of mind on the wiring harness components.
  • Battery PWR/GND Gauge 4 AWG
  • Amplifier PWR/GND Gauge 8 AWG
  • Speaker Wire Gauge 16 AWG
  • Fuse Type MAXI
