In Stock, Will Ship Within 2 Business Days

This is a plug-and-play, isolated, RCA input adapter harness to connect the 2006-2012 Harley HK radio, to the RCA inputs of most high-powered 12v automotive type audio amplifiers.

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

This custom built J&M adapter harness will also remove the “speaker fault” condition when running the Harley HK radio diagnostics & eliminate any possible DC current that might otherwise travel between the HK radio and the amplifier.

Amplifier gain control adjustment guidelines also included.
