No Bass after 5 seconds!

Hello, I recently bought my 2007 BMW E70 last week. I am a dealer but bought this car for my personal use. Love it. Recently had a 745i. Anyway when I start the car the bass only works for about 5 seconds and then stops. I changed the battery and had my local mechanic reprogram everything and run calibration with no defaults. Its driving me crazy. Any ideas. Everything else works great with no issues. I took the amp out today and everything looks good. He showed it communicating with the MOST system.

Thanks,
Daren

Hello I have a E70 2007 BMW X5 that I recently purchased last week. Im a dealer so I do not know the history of it. I did have a new battery installed and reprogrammed. Diagnostics were run and everything thing checks out good. Any ideas why the subs would not work after about 5 seconds or less? I took the amp out today and it appears to be in good shape and the diagnostic software would communicate with it also. Any ideas?

Thanks,
Daren
