I have an 07 NBS Silverado 1500. It has the basic sound system, not bose. The bass is pretty good for being a base system...but on certain "notes" the panels on the doors shake and there is an annoying vibrating noise. Any tips on how to stop this?
Couple things: You can add seem sound dampening material. You can check to ensure the speaker itself is mounted properly and not loose in the door panel. You can check to ensure that the door panel mounts are indeed secure to the door itself. If not, replace them.
Hope that helps.
