I have a set of 8" subs under the rear seat in my 2011 crew cab. I have a TON of buzzing noise coming from the rear door lock sliders when there's any kind of bass going on. If I unlock the doors it either gets better or goes away. I tried taking some thin adhesive padding and putting it between the lock slider and the door panel, seemed to work for a little bit but now the buzzing is back. Anyone else experience this, and found a good fix for it?
