I installed this under my 1994 Mazda MX-6's rear deck, quarter trim, rear seat, door panels, and most of the plastic console & dash pieces. It's made a big difference! The rear material has quieted the exhaust and given the car a much more premium feel, and the added weight in the doors helps them close with a more solid *thunk*. In addition, the extra weight on the plastic trim changes their resonant frequency and helps eliminate squeaks & rattles.

The material is easy to work with and lay down. Easy to cut with heavy duty scissors or an X-acto knife. One thing to keep in mind is that for best adhesion, the surface needs to be free of any coatings. I had a plastic protectant spray on the inside of the trim panels, and the sound deadener didn't lay down very well until I stripped it off. Overall, highly recommended!

I know, I know Amazon doesn't make the Amazon products that carry their name. Whoever made this sound deadening material did a great job. It was priced about the same as the other mid range material on Amazon. I went with this because of the size 18″ x 32″ (9-Piece). The larger size made it easier to cover there door. Not overly thick, but it's heavy. If you use a roller, the bubbles on the aluminum side do not completely disappear like other products do when using a roller

Be sure to prep and clean the area well. The material sticks good and is easy to apply. I had to reposition the mat a couple of times before rolling on. I was able to use 1 1/2 sheets for the front doors and 1 full sheet and the remanence of the front doors to do the back doors. I estimated I would use 8 sheets when in fact I used only 5. I have 4 1/2 sheets left. I also applied about a 1 ft square behind the speaker directly on the shell of the door. I know a proper way yo sound headed is do the entire skin of the door but I did not want to go to that extreme. My sound system install is not for the bump but for clarity and quality of the music.
Used a Sharpie marker to trace out the size from the dust cover on the doors then scissors to cut it out. A box cutter will work as well. Very easy to make holes in the middle with scissors where needed for fasteners and mounting screws. Scissors push right through. It definitely improved the sound in the cabin. Doors have more of a solid sound when closing. Less metal ting from the metal. Better music sound and also eliminated more road noise. Both are a plus. Would I purchase this again? Most likely because of the larger sheets offered.
