Installed the J&M CB2003DU intercom. Put on the helmets and turned on the radio, and it works !

While sitting still, the clarity is great and the volume is OK. Start up the Valk, and the audio is still audible. But when running down the road, the volume is too low to hear on the intercom. I can still hear the CB fairly well, but the intercom is just about inaudible for both of us. Yes, I have loud pipes (TBR6X6) and yes, LOUD music in the 60's has rendered me partially deaf,

but SugarPlum can hear a fly fart, and she can't hear me on her headset either.

Any clues you guys know? I've emailed J&M tonight also. John has been really great about getting back to me very quickly on previous emails, so I'm anticipating his response within the next several business days. I'm open to any and all suggestions as to how to make the intercom's audio louder. Suggestions to change out pipes on MAGNUM will be ignored!
