If the amp is a class D, which I would assume it was since it is in the fairing then there can be an issue with the amp interfering with the radio reception. I have seen it with multiple companies when the class D amp is mounted near the antenna in the trunk next to the antenna. Nothing short of moving the amp or changing it to a manufacture that has fixed this issue will work.

True, class D amplifiers can be an issue. However, the OP hasn't indicated that it is a class D amplifier. If it is, then the easiest/best solution is to replace the amplifier. If the original install was done by an experienced shop, they would have likely not used a problematic class D amplifier in this application. Again, I'd check the obvious first.

Here's a recent bulletin updated a couple weeks ago regarding class D ampliiers and antenna placement. on Harley Davidson's.

ISSUE:

Class-D and Class-A/D amplifiers have power supplies that switch on and off at high frequencies, which can emit EMI (Electro-Magnetic Interference) signals into the air. These signals can cause interference with signal processors, wireless devices, and radio waves including AM and FM signals. Modifications in amp designs have been made to keep this to a minimum. However, devices that are in close proximity to the amp can still suffer from such interference.
SOLUTION:
1. Mount the amplifier as far away as possible from the motorcyle’s radio, antenna and antenna cable.
NOTE: Antenna placement seems to be key. Bikes with a rear whip antenna seem to be O.K. Fairing mounted aftermarket antennas do not work when amplifier is mounted to radio.
2. Keep amplifier cables - which carry interfering signals - away from radio, antenna, and antenna cable.
3. Provide a good amplifier ground. Ground cable should run directly to battery. Grounding an amp to motorcycle fairings or forks is insufficient due to higher current requirements of amplifier.
4. Aftermarket tuners are more susceptible than factory tuners to noise issues. Amps mounted close to aftermarket radios have more interference than amps mounted to factory Harley-Davidson radios.
5. Some stations might get skipped by the SCAN function, but if manually tuned, will come in fine.


2014 & NEWER MODELS ONLY:

2014 Harley-Davidson Street Glide FM Recpetion - Page 2 -- posted image.2014 factory Harley-Davidson radios have a “Cat Scan” - if not set up right - will not allow tuner scan to stop on all channels. A software reset may unselect previously chosen AM/FM search categories. To resolve, enter “Cat” menu and check each genre to include when scanning radio stations.

Still haven't pulled the fairing but I did try the reception test. It does get am/fm reception inside our interior/exterior tin walled shop...the amp is a new 4-channel Rockford fosgate that I believe is a class d or class a/d. No plausible way to shield the emi without moving the amp? I know moving the amp would proly be the easiest way but the customer doesn't really want to have it relocated

I have a roadglide with amp against head unit, and another in a saddle bag, reception was terrible, found that it came with a hidden antenna in the fairing, put a new one at the back of the back of bike, all good now..
