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

This stuff works as advertised. I installed it after installing 6.5 inch speakers and an amplifier in my truck. Without the Dynamat, the metal in my door audibly echoed with EVERY bass note and kick; very annoying. However, there were literally no vibrations and road noise with him. actually decreased. The sound quality, bass and treble, has also improved a lot, a big plus. If I had to choose minus, I guess I would have to continue with the installation. just screwed up at some point. The adhesive backing is VERY sticky as it will stick to anything including itself. If you are going to put all or most of the paper in any part of your door, put it down first and then slowly peel off the paper while pressing it against the door. The attached video is not the highest quality because I recorded it on my phone and I had to use a program to merge the two clips, cut quality but you can get the idea.
