Customer Ratings & Reviews

I wanted to experiment and try something different on my car. Just watching a few videos online on how its ment to work, plus having the right tools helps alot 10/10

Just enough in the pack to cover the area on the door behind 2 woofers. Get 2 packs of this to cover the area behind all 4 woofers.

Works surprisingly well! Used in our travel trailer to line the inside of the compartment that houses the water pump. Made a huge difference!! We barely even hear it kick on now. Wishing all had thought of this sooner. Was super easy to cut to fit. Pieces had strong adhesion & have stayed out so far. Only downside, it was tough to find in the store. They didn’t have it on a shelf, but back in the shop where they do car audio installs. Had to have an associate go get a pack for me. Would’ve bought 2 had it been on the shelf instead.

I love driving and I certainly love my car. I also enjoy listening to music with high detailed sounds, and let me tell you these give you all the details in the music your listening to. They litrally transformed my experience and made me enjoy my commute to work. I thought since im soending time in my car everyday might as well enjoy it, but i didnt think I’d really elevate my experience to this level. They’re so good and when im selling my car ill be keeping them for sure.

Granted,I did get great advice from the car audio installation folks at Best Buy. My sub was causing some vibration/buzzing issues in my new vehicle and from my research this seemed like a reasonable fix without spending too much time or money on the project. When I went in to purchase it I had to get it directly from the car stereo installation area ( it wasn’t on the retail floor). The nice guy working in the installation area went over the install instructions and advised me to WEAR WORK GLOVES…which I would also stress due to the thin and very sharp layer of metal fairly well hidden in the product. Installation was quick and easy and I’ve noticed a definite improvement. Is this vibration completely gone? No. But it is vastly untouched making it well worth the small price this product is.

Installed these on my front doors during speaker replacement. They change the sound output completely. The installation was very easy and straight forward. It does require a heat gun and some form of a roller. Also a little bit of elbow grease! But it is well worth the investment.

Works really well. Quality material and easy to install.

I'm writing this review mainly to give high praise to the car technician at the Glen Allen Best Buy location. I appreciated Taylor's honesty, and he also did an excellent job installing the speaker kit. It really has helped the vibrating in my door which was causing my speaker to make weird sound on certain songs with a high bass. Very happy with the service I received, and with this product!

This product was easy to install and easily molded to custom fit the door panels. It cut out the vibrations in the panels and made a noticeable diffrence in the sound quality.

Had this installed for my car speaker because of a rattling noise and not only did they eliminate the rattle but the sound quality is so much better. And for the price of $25 it’s a well worth investment in my opinion cause you can do two door panel. Had it installed at Aiea bestbuy car audio team, and I highly recommend them if you don’t do it yourself.

Great product easy to use, same quality as Dynamat.

Was looking for DynaMat but found this at my local BestBuy. Look and works just like DynaMat and it's cheaper, I used this in my trunk and have no complaints. Less rattle and general road noise and hasn't been affected by the heat. Goof stuff, definitely recommend.

Good product to quiet the rattling from the bass. Easy to use and install.

Install= buy a roller and clean surface, it's worth it for the sound deadning/distortion from the door panel. I was skeptical until I turned on the radio and drove on the highway. This stuff cleans and tightens up the sound!!!!!!!!

This product was used for a stereo install. The system sounds excellent. There are no unwanted vibrations from the speakers. The sound is rich and full with no extraneous sounds.

Very good easy to use works like it says made my speakers sound great

Great material for keeping unwanted sound out of your system

I put these in my trunk and around trunk and can tell the difference right away getting one more box but that's it cause they cost too much for so little but quality is very good

This is a great way to get better sound from your car speakers. This kit covers a basic 2-channel set up and is designed to mount directly from your speakers. It drastically helped my system...definitely recommend.

Used this to soundproof my 2009 Nissan Maxima for a stereo install worked excellent. No external rattling and held in the music well with a 2400 watt system. Would highly recommend.
