The Kit You Need When Adding a Rockford Fosgate Amplifier to your 2014+ Harley. This Harley-specific kit Includes all of the wiring and brackets that you will need for a bolt-in and plug & play. This includes a very cool T harness for your factory radio that gives you both front and rear radio signals as well as front and rear speaker outputs for your new amplifier. By intercepting the radio signal directly at the radio this harness eliminates the need for any other special harnesses no matter what version of bike you have. Brilliant!

This complete kit includes a heatsink, bracket, and wiring harnesses needed to install the Power Marine TM400X4ad amplifier in 2014 and the newer model Harley-Davidson motorcycles. The kit also includes Y-adaptors for adding lowers or Tour-Pak speakers, Boom!™ Audio bypass plugs for factory amplified systems, a DSR1 loop-thru harness, and all necessary hardware.
