Left Front Speaker Vibration (Bose)

[SuthrnZ71]

I've read on here where people have had vibrating or buzzing with the front left Bose speakers and it ended up being the door parts were rattling.  Well mine is at dealer getting a few things looked at and the service person said it was doing that because I had the bass all the way up, however I've always kept the bass up full and never had issues with other trucks/vehicles.  Does that sound about right or you think they are trying to avoid taking the door panel off?

Mine does the same thing. I haven’t pulled the panel yet but I won’t  bother the dealer with that. I save the big things for them.

Yeah I was having them check a couple other items so figured I would check the speaker vibration, they said it was from having the bass up too much.  Oh well, will try it how they set it for a bit.
