Why REMIT:  All motorcycle Class D amplifiers lead to a reduction in FM radio reception, regardless of brand.  Wild Boar Audio amplifiers use proprietary technology called R.E.M.I.T. (Reduced Electro Magnetic Interference Technology) giving superior FM radio reception over all other amplifiers.  
If you add a second or third amplifier to your system any reduction in FM radio reception is considered normal.  If FM radio is important for your riding experience, we strongly advise against the use of any in-fairing antenna, the factory antenna works best.  Please note that satellite radio and GPS signals are not affected by Class D amplifiers.
