I've noticed driving to work the last 2 days that the center channel (10 speaker Bose system) in my 2009 LTZ has progressively started rattling more and more. If you press down on the speaker grate in the center of the dash you can almost feel the speaker bouncing around in its basket. I'm suspecting a loose screw or a broken tab but it looks like its a tough place to get to.

Does anyone know how to get to this speaker? Does it entail removing the entire dash to fix this? Does anyone have instructions on this? I am decently capable of doing this myself since I've done car audio systems in the past and would like to avoid yet another trip to the dealer in less than 2 weeks!

 

I have the same problem. Did you find a solution?
