Note 1: The QC 475-RM 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 QC 475-RM 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  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!

Note 2: From a sonic point of view, Road Glide Ultra has the correct flash, however, the factory flash in Road Glide Ultra makes the radio play considerably QUIETER than it could. Less signal out from the radio means less signal going into the amps. If you install this system without a reflash,it will sound great, but will NOT reach its potential volume. A radio reflash by a Techno Research dealer is required to make this system play to its full volume potential. An OEM Dealer reflash will not “fix” this, as the OEM flash looks at the bikes VIN and will re-install the same “quiet” flash.
