I have a Biketronics BT2180 2X180 amp and a Kenwood radio. I have been running this on my 2010 FLHXXX for about 3-4 years. A few weeks ago I was out enjoying a spring ride listen to some tunes. I hit a pothole and all of a sudden all I had was crackle and other squeals that made listening impossible. Today I took the front off and checked for loose wires. I unplugged and re-plugged all of the connectors, I have the sound back but I have a constant medium pitch squeal/hum. Never had it before, any help or ideas as to what I can try. Thanks.

 

I just had a similar issue with my bike and it turned out to be my Scosche hand control module.

 

Thanks, I have the BIKETRONICS (#BT1005X) RETRO RADIO 98-13 FLH/T not the Scosche
