Dynamat Xtreme Sound Deadening Car Insulation Single Sheet Hex Pack 10425 – Noise Dampening for Floor, Doors, Hood or Trunk – Easy Self Adhesive Install – Made in USA – 1 Sheet 18”x32”, 4 sq ft

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.

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!

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.

It has excellent adhesion and sound insulation, though there is a slight odor.

I installed a basser box 10 inch in my Audi s5 sportback in the right side compartment. I had it for a months but just added this sound deadening behind it. It made such a huge difference. The rattle from the metal panels are gone and all the sound goes into the cabin instead of out of the side of the car. Pretty easy install and I didn’t even use a roller tool.

Excellent product that meets the description very well. It is firmly adhesive and stays in place after it is applied and it can be rolled out flat very quickly making a nice smooth surface.

I bought a Fluance RT83 turntable for my adult granddaughter (she's new to vinyl). The thin aluminum platter rang like a bell when I tapped on it with my knuckle, not good. So I found this Dynamat Xtreme Sound Deadening material and cut and applied it to the underside of the bell, I mean platter. Wow this stuff did the job. Now all I get is a dull thud when I knock on the platter. After cleaning the platter with Acetone, the deadening material sticks really well. I'm going to keep the left-over piece to dampen amplifier cases etc. Two thumbs up Dynamat.

I bought Dynamat, not for a car as its intended use, but for my new stainless steel kitchen sink. I could not afford one of those high dollar sinks, and found one online thru Amazon that fit within my budget. I knew there would not be much in the way of insulation to the sink, making it have that "tinny" sound, so I went to researching a way to sound proof it and also help insulate it and keep a sink full of hot water hot longer. I found one review about the Dynamat online, then came to Amazon to see if they carried it. Of course they did! One roll fit my sink perfectly and now installed you cannot tell that my sink is one of the "cheaper" models by the sound. And an added bonus...water remains hot in the sink for hours. My plumber was dully impressed by the product, as have been all my friends. Just remember to use gloves while working with this product, as it has a light sheet of aluminum foil that can be a bit sharp if you run your hand across it. It is an excellent product, even for house hold use. :)

Worked well easily to use.

I bought this for my car's hood. I must say the result is excellent. It eat almost all vibration and noise coming from engine bay. I feel the tones from my car's music system is even better because noise kills the low bass tone. Installation is very easy , just peel stick, cut the excess and stick the remaining cut pices around to form a symmetrical art look. Before starting the installation don't forget to clean thoroughly the paint surface. Inside the pack you have dynamat sheet, 2 dynamat stickers. I love the one stcker with 3d appearance. Finally, if you are a person who love silence inside ❤️ your car, this is for you. A must try and value for money product

Great product!

Works as described. Added it to the rear parcel shelf of the car where I replaced the stock subwoofer with a larger Pioneer subs. Seems to settle down some of the vibration.

Dynamat is not what it was 20 years ago, I order it it comes, I email them saying “ are you guys playing a joke on me?” This stuff you send I would make actually make more noise, and cheap stuff is probably so toxic too, so they reshaped a real type of quality but still not what it suppose to be
