its worth the couple hours it takes to chase down the little vibrations. I eliminated mine right after purchase and have had 37000 miles of relative quiet. Mine is a relaxing space to be in. I can crank my volume on every genre of music. Biggest offenders were 1. sunroof velcro clips, fixed with rubber padding between clip and headliner side, 2. a module under rear seat near middle floor, fixed with double sided foam tape, 3. rear slider, fixed with application of the fuzzy side of velcro tape placed between the glass and frame on each upper corner of the glass, 4. added rubber between each mounting bolt of the subwoofer and the rear cab wall. Sounds like a lot to do, but only took a couple hours, and no tech crawled inside my truck to half a** the job and scratch up my interior. 2 years later, all remains quiet.
