2011 M3 conv premium sound audio question

[M3chris]

Anyone experience an uncomfortable loud boom when blue-tooth phone hangs up and you have loud music in the background. I know you are all going to say lower the volume of your music, but with the top down my music is always loud and if you get an incoming phone call, you have no chance of lowering the music volume prior picking up the call. I never had this problem with my 2007 335i Conv with perm sound (which I have to agree with some of the folks here that the Logic 7 prem sound of 07 used to sound better, but I am also hopeful that breaking in the speakers would change this comment).

Any suggestions?

I have the same issue, I think it's because each source has its own volume setting and that crack is from the amp trying to catch back up, so to speak, to the music, or it could be due to the amp switching from mono 8 bit (the cellphone I believe) to the full surround sound of the music

It's pretty annoying...I never had that issue with my 07 335i.
