Review on Dynamat 10435 12x36x0.067 Sound Deadener: Self-Adhesive Xtreme Door Kit for Effective Noise Reduction by Ross Bagby

Get the Original. And by the way, it's half the price here compared to Crutchfield. Dynamat is not easy to install. It cuts your fingers, leaving a black, sticky material on them. This will test your will to dismantle panels and flex your body as you enter spaces where no human foot has yet set foot. But - you will survive and this is what you will have: Amazing sound. Tight doors that don't rattle but slam shut. A controlled vibration surface for your speakers that will blow your mind, especially when you crank up the volume. The main problem with any type of sound control is reducing vibration and eliminating the possibility of surface resonances at certain frequencies, and Dynamat does this in peaks. convinced that it was worth it, but you also want to leave it and pretend that the sound is right. But I tell you, it's worth it!
