From time to time the right door subwoofer in my '08 GT has an annoying buzz on certain bass notes. pushing on the grille can make the buzz go away, so I think I need to remount or pad that grille somehow. How does that remove? Is it just snapped on? Thanks

There should be a TSB about this.
I had the same issues with my 07 so I took it in they first thought shaker so they gave me a new head unit buzz was still there so they then replace 1 of 4 amps it was one up front then when they got it humming nice I put in a Pioneer Nav unit
