      Dynamat install

      Purchased 2 of these boxes to install in my S2000. Was just enough to do passenger compartment, behind door panels, inside doors and trunk. Product was easy to work with considering how cold it is right now (under 10 degrees Celsius) with the help of a heat gun. Hopefully this will improve the sound quality of my stereo and get rid of some of the road noise. Can't give you a final verdict yet as I'm still a few weeks away from getting the car on the road, still a little chilly in the great white north.

      Easier than expected

      This box is more than twice what was needed for a 79 F250 ceiling. Measured and cut easily with a box cutter. The hardest part of the process was working overhead; make sure you have an edge where you want to start, and just peel, smooth as you go, and voila. This project will be covered by the headliner; looking forward to feeling and hearing the difference it makes.

      Auto Sound Insulation

      Have used Dynamat in 4 different cars now, and consistently fine it easy to configure and apply, and it is very effective in reducing sound intrusion into the passenger compartment. Also, when applied around the mounting base of your speakers, it improves the sound reproduction of the speakers.

      Used on a regular cab truck

      This kit was enough to do the roof, rear cab wall and entire floorboard of an 07 GMC Sierra classic regular cab truck. Very sticky stuff. You had better have it where you want it when you start, because you aren't going to pull it back up and reposition it. Don't think this stuff will ever loosen and fall down. Going to get the door kit to do the doors and the entire cab will be complete. Don't know about the sound deadening properties of it yet, because this is a project truck and not the daily driver yet.

      Hear the difference!!’

      Awesome product .. you can hear the difference it makes inside the car especially if you have a loud exhaust this sound deadening mat really works! Plus if you have a sound system that really bumps it truly helps and improves the sound quality. No more rattling in the cab.
