This is a custom made, wire-crimp spade adaptive, plug-and-play, isolated RCA input adapter harness to connect the 2006-2013 Harley CVO Ultra (only) HK radio's front channels, to the RCA inputs of 'J&M's ROKKER™ & Performance series amplifiers.
Use this harness when adding 2 or 4 additional speakers, to the existing 4 speakers that are being driven by the Harley amplifier, that is already installed under the tail trunk of a CVO Ultra.
A good example of this is when installing two additional speakers in the LOWER fairing position, for a total of 6 on the CVO.
You would connect the front channels of the Harley amp outputs to the new lower speakers, then install a 'J&M amplifier into the fairing, and connect the 'J&M amplifier to the UPPER fairing speakers.
You would use this harness to give the 'J&M fairing mounted amplifier the audio signal from the Harley HK radio, while still maintaining proper signal input levels to the rear mounted Harley amplifier.
Included are easy to follow installation instructions (also video below) and amplifier gain adjustment recommendations.
