Works great! Will be buying again!

Good value.... adhesion was great...easy to install...helped was sound quality no rattling...ease to cut laid speaker on top went around with box cutter twice... didn't really sniff it it wasn't your momma's panties.lol

I drive a 1989 Toyota MR2. This vehicle happens to have the engine, and transmission in the middle of the car for weight distribution purposes. They car idles at 2000 RPM when cold, which produces a tremendous amount of noise and vibrations. Also on the road, especially the open highway, they car SCREAMS doing 65 mph at 4000 RPM. Something had to be done. BOOM MAT. I lined roughly 40% of the engine lid surface area with boom mat, and the results are awesome. I had plenty of boom mat left, so I applied it to various parts of the engine bay's panels. Perfect. Now the car is quiet and smooth. I can now hear the air coming out of my vents, and other little things inside the car that I could never hear before. I highly recommend this product for sound and vibration dampening purposes. It's easy to mold, cut, and sticks to anything. Just make sure the surface is dirt free, and you're in business. I used sheet metal sheers to cut the boom mat for my application, then bent and molded it around corners, bumps, and dips. You can feel it firmly adhere to whatever surface you choose. This product is truly one of Amazon's best!

I purchased these to use in a restoration for a classic muscle car. I loved the product, but for the price you don’t get a lot of mats. I was planning to make a second purchase and discovered a different brand called “kilmats” they are exactly like boommats, only you get a lot more for your buck. Both brands are installed and the car is good!In the picture for reference; the boom mats are black and the kilmats are silver. Both are equally the same quality!

I bought this four pack to cover up the chassis under my rear seats due to the noise of the RWD drone getting a little annoying on long road trips. It was just enough to cover everything, and it did reduce noise! People in the back seat can now understand someone sitting in the front without having to strain to hear. While I didn't use these for a typical install (like around door speakers or subs in the trunk), I can say without a doubt that it was a high quality product and was painless to install. Just peel and stick, smooth down as desired, let mold/dry for about an hour if you want to be safe, and then replace door cover/seats/trunk lining/whatever.This may not matter, but only one of the sheets has the BOOM MAT logo imprinted on it, the rest are just unmarked plain sheets.I can also add that they have virtually NO smell, and they have stood up to 103 degree days without stinking up. I've heard cheaper sound deadners can cause a smell in high temps due to cheaper materials. This is just something I saw while researching deadners, and having no smell was important for my purchase.

Density was good and the adhesive was great. Changed the resonance frequency of a vibrating panel. No more vibration noise.

They work good as a sound damper, we put on floor or a 1963 f100 truck, easy to cut and install

Boom Mat is an awesome sound reducing insulator. This past weekend , August 2022, I covered the complete interior floor of my 1933 Ford 3 window coupe, It's important to cut a cardboard template of oddly contoured spaces , then transfer to Boom Mat for an exact fit and professional look. Sorry no images are shown. I'm following this up with DEI under carpet sound insulator , then carpet. The Hot Rod air conditioner and sound system are definitely going to be enhanced as well . 8hr install time resulted in a spectacular finish. Highly Recommended

El paquete llego en buenas condiciones, se observa buena calidad, se pueden realizar los cortes de manera fácil para su aplicación ya que no es muy grueso, mejoro el sonido de las bocinas y le da masa a las puertas, faltaría ver su comportamiento a largo plazo.

This stuff isn’t just for automotive use. I assembled a new computer system recently and the combination of motherboard fan and a big 110mm case fan set up some vibration. Since computer cases have large expanses of mostly flat sheet metal, there was an annoying resonance setting up in the case. I knew exactly what I needed and this product solved the problem; I knew it would. Vibrations have been eliminated and the system is practically silent. Great stuff!

Very effective, easy to put down

Used for damping metal panels for audio applications. Worked very well and was very easy to use
