CANOPUS Car Sound Deadening Mat - 80 mil, 18 sqft, Butyl Sound Deadener for Trunk, Doors, Floor & Ceiling, Audio Dampening Material, Pack of 9 Sheets, Black

This stuff is thick and worked great for sound deadening my truck doors. I was a little skeptical based on the price but they have great adhesion and are very thick. They don’t smell bad and the foil didn’t tear easily. Definitely plan on buying more for the floor and firewall when I get around to doing that job.

I installed a stereo system in my vehicle bit the bass was rattling the door panels and it sounded annoying. I decided to purchase these mats and what a BIG difference! The installation was super easy and now I don't hear any rattling and the sound is clear and crisp now. The mats are heavy and of very good quality so durability isnt an issue and I was surprised that they didnt have a strong smell.I must say that they're worth the money and the customer service is awesome! I highly recommend

When I had to replace the window motor, I covered the driver door on my motorhome before I put the door cover back on. I HAVE noticed less road noise. I've got enough left in the box I ordered to do the other door. Waiting for the window motor to go out on that door now... In thinking about it, I think it is soundproofing as well as insulating. The product is heavy so keep that in mind on projects you use it with. My door has a solid sound when it closes now instead of that tinny door-closing sound. The additional weight on the door actually makes it close easier with less effort than it did previously.

Good product easy to use. You can cut to the size you need for certain areas. It is a bit expensive considering, but this is probably one of the more inexpensive choices.

After doing some research I decided to go with the Canapus sound deadener for the stereo build in my c4 corvette. The material lays down well and sticks great if you roll it. Once I got the system in I was pleasantly surprised at how good of a job it does keeping the sound in the car and reducing vibrations.

We recently purchased Canopus Car Sound Deadening Mat My husband installed it inside all four doors of his Prius last weekend. It installed very easily and really stays put when you adhere it to the frame. It was easy for him to cut and work around all the screwholes and wiring in the door. We took it for a test drive and it makes a huge difference. It was easier to talk to each other and considerably cut down on road noise. The stock doors on a Prius sound very flimsy when you shut them and with the new sound deadening mat, the doors sound much more solid now. The product went further than we thought it would but we plan on purchasing more so he can install it in the floor of the car. We think that will make an even bigger impact in reducing road noise.

Bought these for my Camry, they work great. Easy to apply and made the road noise noticeably quieter. I will probably get some for my doors as well. Great product.

This is the best sound deadener for the money. It feels premium, odorless, and is priced cheap. It’s thick and sticky with a sturdy backing. This is my favorite and I will continue to purchase this for every build.

So to start I have degreased anything that wouldn't promote adhesion and they still don't stick very good. I have also rolled over the product with a roller to promote better adhesion and it almost made it worse at times. I'm not sure how long this will so a further review in the future may be necessary.

Producto de muy buena calidad

Très bon produit, vraiment très bon, il se positionne facilement, la coupe est aisée, il adhère bien, je le laissais chauffer au soleil avant la pose pour rendre le produit moins rigide, un sèche cheveux doit aussi faire l'affaire. Comme tous les produits insonorisants, il faut vraiment en mettre partout pour que le résultat soit spectaculaire mais rien qu'en insonorisant le coffre, ça se fait déjà bien sentir.

I took great car to install these properly in my cars wheel arches. It made absolutely no difference whatsoever. Pointless.

Prima product. Een tip, leg ze even in de zon voor je ze gaat plakken. Dan hechten ze nog beter.
