What's up guys? I've been wondering, would it do me any good to just sound deaden my 4 doors and the back hatch? Right now I feel like my tahoe is falling apart with the vibration so I want some deadening asap. But my box is over 400 lbs and I don't really want to take everything out to sound deaden the roof. So my question is, will it even help me to just sound deaden all the doors on the tahoe? And db wise, how much will it help if i deaden everything?
