This is a J&M plug-and-play, isolated, green-band RCA input adapter harness to connect either version of the 2014-2020 Harley Infotainment radio’s REAR-SPEAKER-OUTPUT plug connection on the back of the radio harness, to the RCA inputs of most high-powered 12v automotive type audio amplifiers.

Use this harness to bring the rear channels of the amplifier input gain controls into a useful range of adjustment, when setting up and tuning a high-performance Bagger audio system.

Special Note: This rear-speaker output connection point may not be active for certain 14-20 Harley bagger models until a Harley radio flash is performed to activate the front/rear fader control.
