Note 1: Street Glide and Road Glide (Non Ultra) models require a radio "reflash"

Note 2: Ultra models require WBAURH "Ultra Rear Harness" to make the radios fader continue to work. (Drag Specialties Part # 2120-0900)


Note: The WBA 600.4 Amplfier is a Class D design. It should be understood that ALL Class D amplifiers, regardless of brand, cause a reduction in FM reception. The REV 225-AA features a proprietary circuit design called R.E.M.I.T. (Reduced Electro Magnetic InterferenceTechnology) that Hogtunes believes gives the BEST FM reception available for any Class D Amplifier designed for a motorcycle.If you add a 2nd or 3rd model amplifier to your system, reduction of FM reception is increased and is considered normal.


Hogtunes understands that some riders prefer the cosmetics of in-fairing antennas, however it should be noted that NOTHING works as well as the factory antenna. If FM is an important part of your riding experience, we strongly advise against the use of any in fairing type antenna!
