I know this one has been beat to death....I have looked at i think every post here on the topic...I have a 2015 street glide and have the big boom radio....I have the amp on top where it can go and yes its a class D amp...Did have H/D power hidden antenna its gone now tried a J&M flexpower antenna NO help its gone now I have put factory antenna back on NO help...I took 8ga. power-ground and twist them from batt. to radio...also twisted both speaker wire all the way...maybe gained 1 station back....I understand the RF signal messes with AM/FM signal....Sooooo is there a shield of some kind to use??? OR is there no answer to this other than a class H amp i,m told by the amp tech. support? JUST ASKING THANKS

 

hmm- I'd reposition the amp- throw it in a saddlebag.

'quality' electronic goods should be CE certified and not radiate RF unless something is broken

I have the RZ D2000 amp. Had the same issue. Also was helping a friend. Found an answer that worked for us both. Used some copper tape. Do a Google search. Blocks EMI. "Electro magnetic interference" . I bought some 1/2 inch about 3 FT. Also some 3i nch by 10 feet. Both were about $10 total from Ebay. Also saw some at Homedepo. I wrapped the antennae wire. As far back as possible from the radio. Also layered the top of HU. I now have excellent reception. My buddy is going to try it this week. It should work for him. I gave him what I had left. Should be enough. Tape has the consistency of aluminum foil. I used the wide stuff and cut strips. Good luck

 

Satellite radio fixed mine.

 

You can build a Faraday cage. Just wrap it in copper window screen

 

Stream.

 

Change the amp to one of several others.

Arc 600.4
Stinger 700
JL 600.6
SD 800.4
Mmats 4110

Some amps just kill FM, others not as bad. Fairing antennas and amps don't play well together.

 

What's FM radio?

 

A Podcast from Fuel Moto, maybe???????

 

FM radio has sucked ever since two companies bought all the stations.

Sorry, can`t help with any advice on a motorcycle mounted radio, never had one....
