Rockford Fosgate RFPOL-RC34

The Ride Command audio interface (RFPOL-RC34) is designed to connect Rockford Fosgate amplifiers with a factory Polaris Ride Command source unit. The two-part harness taps both front and subwoofer audio signals from Ride Command, actively filters any electronic noise caused by the DYNAMIX suspension system and feed them to a TM400X4ad or M5-800X4 amplifier.

The front channels power the front audio, and the rear channels power the subwoofer. The kit also allows you to take advantage of built-in Ride Command® crossovers for the best sound possible. Since one harness interfaces with the front/rear speaker amp, and the second connects to the subwoofer amp, it ensures Ride Command® properly distributes the correct audio frequencies to the proper speakers.
