I'd start with checking your AMP ground wire. Many installers will try and use a ground point close to the AMP, but I personally think that's a mistake. I always take the ground wire clear back to the battery and connect directly to the battery or the grounding terminal that Harley puts near the battery. I'd venture to say that a large % of people plagued by popping, hissing or static after an install of quality audio gear can be traced back to a poor choice on the ground.
If the ground connection looks good, make sure that the installer used the appropriate gauge 12v and ground wire. Inspect the wire insulation and take a look at the routing of the power and ground wires.
BT makes good gear, so I'd eliminate all of the potential issues of a poor installation before I assumed it was the BT2180.
If push comes to shove (or this might even be the first and best choice of action) contact Bill at Biketronics and ask him for his help in trouble shooting the issue.
