    Anyone here use sound deadening on there Prius' ? I hear a lot of people complain about how poor the factory sound deadening is in our cars.

    I never paid a lot of attention to it, and my aftermarket stereo system does a pretty good job at drowning out road noise...
    But then I spent some time and money deadening my truck, and wow ! What a difference. So then, I walk back over to my Prius and open and close the door, and it sounds like a tin can ! Seriously thinking about using a good amount of deadening on all four doors, as well as the roof.

    I know from experience with my truck, getting all the panel ripped off / open, is the hard part, and my friend / mechanic has all the tools and experience with that anyway. The deadener itself cuts, and sticks on quite easily.

    Anybody done this, or considered it ? Maybe even aside from an upgraded stereo system ?

    I'm curious, as well. Where I hear most road noise is from the rear of the cabin. IF I were to tackle this, I'd dampen that area first, probably simpler than removing door panels?

    Honestly I don't think the door panels are too tough. The roof liner might be more of a PITA...
    Hey one other cool thing about the deadener, it doesn't have to cover a whole area, to give really good deadening. So say you are only able to get in and cover 40% of the inside of a panel. That really might give you 95% deadening. It's kind of hard to explain, but sound / vibrations travel through sheet metal, then get to a spot with deadener, and that spot just soaks up that energy, and it travels no farther.... If that makes any sense...
