This is a J&M plug-and-play, isolated, green-band QUAD-configuration RCA input adapter harness to connect to the front-fairing speaker wiring harness on the 2014-2020 Harley StreetGlide or RoadGlide/special, to both the front & rear-channel RCA inputs of most high-powered 12v automotive type audio amplifiers.

Use this harness to bring the front & 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.
