Review: Magnificent - I used this to wrap an aluminum cold air intake that was just loud. Did a double wrop with what vame in the package and it reduced the roar enormously. Easy to cut, sticks great and works magnificently. Such a great value over replacing the tube. Extremely easy to use. Absolutely odor free.
Review: Amazed at the effectiveness of this product! - I have been an car audio enthusiast for many years, but had previously not used this product. I recently upgraded the rear factory speakers in my 2013 Honda Accord coupe with a pair of JL Audio 6.5" coax speakers and decided to use Dynamat with the install. My EX-L V6 Accord came with 2 speakers and a sub mounted on the rear deck above the trunk. The metal mounting surface has multiple small holes in various areas that prevented the trunk area from being a tightly sealed enclosure for the 3 speakers. I installed the new JL speakers in place of the factory singe cone units and tested their performance for a bit before applying the Dynamat and reassembling the rear trim onto the deck. The new speakers were a big improvement, however after installing the Dynamat and closing the trim up the bass response from the rear speakers and sub was amazing! It sounded like I had added an aftermarket amp to the sub. The rear deck has a rather irregular surface and required cutting quite a few separate pieces to be installed sort of like a jigsaw puzzle. My son and I took our time and were able to completely cover about 90% of the area using just a little over half of the 18" x 32" sheet. The acoustic improvement was so impressive, I will now likely plan to address the inside of the trunk lid and the inside of the door panels. I couldn't recommend this more highly!

### ⭐⭐⭐⭐⭐ Easy to put cut and install.
*by J***E on April 16, 2017*

I was always sceptical of this stuff, I have a 2012 Mazda 6 and I used this kit on the housings for my rear speakers in the trunk/cab divider, my brake like housings and my license plate. The difference is astounding. I no longer rattle all over town but instead have a satisfying, tight, low tone rumble while listening from the inside and outside of my car. If your like me and trying to reduce the rattle heard from outside your car it's important to listen and find the problem areas. Open your truck and listen to brske lights, close trunk and see if you notice differences to help you pinpoint the problems. Gas covers and the inside trunk panel are the other usual rattle areas. If you can't figure out where it's coming from you will end up putting this stuff on every inch of your car. Which would be awesome but certainly expensive.
