Adding an amp to your Harley?

Features

Overview: The Rockford Fosgate RFKHD is an amplifier wiring and mounting kit for installing select Rockford Fosgate amplifiers on certain 1998 and up Harley-Davidson motorcycles. The kit includes precut lengths of power, ground, turn-on, and speaker wire, plus mounting brackets and hardware. The wiring and mounting kit will support 2-speaker and 4-speaker systems.

Amp Compatibility: The RFKHD is compatible with the following Rockford Fosgate Punch PBR and Power Compact Chassis amplifiers: PBR300X2, PBR300X4, T400X4ad, T400x2ad, TM400X2ad, and TM400X4ad.

Motorcycle Compatibility: The RFKHD contains a mounting plate, heatsink, and wiring kit for installing the above listed amplifiers onto select 1998 and later Harley-Davidson Street Glide and Road Glide models; specially designed brackets are included for 1998-2013 Street Glide, 1998-2013 Road Glide, 2014 and later Street Glide, and 2015 and later Road Glide models. These brackets have pre-drilled holes that allow you to bolt them to the chassis using the OEM mounting holes. The included wire harnesses are pre-loomed and terminated to use the OEM connectors.

Wiring: The cables included in the RFKHD use 100% Pure Crystal-Oxygen Free Copper (PC-OFC), and meet or exceed AWG (American Wire Gauge) requirements. The wires are terminated with the appropriate hardware. The wiring kit includes the following wires and harnesses:

  • Power Cable Assembly: The Power Cable assembly includes 5' lengths of 8-gauge power and ground wire, and a 15" amp turn-on wire. The power wire has an in-line Maxi fuse holder with a 60A Maxi fuse installed. The power/ground wires are terminated with ring terminals.
  • Rear Cable Assembly: The Rear Cable assembly consists of two 10' cables: Rear Input and Rear Output. The Rear Input has a 4-pin Molex connector on one end and male quick slides on the other ends of the color-coded left +, left -, right + and right - wires. (If installing a 2-channel system, this cable is not needed.)
  • Front Input Cable: The 19" Front Input Cable connects between the front speaker outputs of the head unit and the amplifier input. It has two proprietary connectors on one end, and a 4-pin Molex connector on the other end. When installing on a 1998-2013 model Harley-Davidson, the Input Adapters (below) will be needed.
  • Input Adapters: The Input Adapters are also for 1998-2013 models, and consist of two 6" lengths of speaker wire that extend between the Front Input cables (proprietary terminals) and the front speaker wires (quick slides).
  • Front Output Cable: The 22" Front Output Cable connects between the amplifier output and the front speakers. It has two proprietary connectors on one end, and a 4-pin Molex connector on the other end. When installing on a 1998-2013 model Harley-Davidson, the Output Adapters (below) will be needed.
  • Output Adapters: The Output Adapters are for 1998-2013 models, and consist of two 12" lengths of speaker wire that extend between the Front Output cables (proprietary terminals) and the front speakers (quick slides).
