I just bought a 2016 road glide ultra and up grated to the boom2 stereo system. It sounds so good on the bike in the dealer ship. Mine sounds not even 1/2 as good. They replaced the rear speakers but it's doing the same thing. When ever the bass hits its distorted. I have the bass turned to the 1/2 way mark and it's still distorted. Dealership really don't know what it is. Does anyone have this system and having the same problem? Any help would be great.
