Perfect For Adding Speakers to Saddlebags! This plug & play three-piece harness adds speaker wire that runs from the bike's front fairing to each saddlebag. The kit comes complete with stainless wire inlets that keep water out and clamp the cable in place. Each saddlebag input section of the harness has waterproof quick disconnects rated for more than 500 watts of insane amplifier power on each pin!

Delux version available here!

The deluxe version comes with a service disconnect at the lid and a 4 pin Molex connector on the amplifier end that is directly plug and play with Harley radios as well as all American Hard Bag, Musway, and Velocity amplifier 4 pin disconnects. These small changes require quite a few additional components and sections to be added to the wire harness assembly but the end result is a slam dunk of an install and a much more serviceable audio system overall.
