KILMAT 50 mil 50 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Works well, within its limitations. Its not going to turn your 90s tin can car into a modern lexus, but it was a pleasant change in my 2012 Miata, making everything sound more solid, the stereo sounds better, and marginally less road noise. Make sure to get the application roller tool, as its essential for proper application. One note, you dont need to entirely cover panels. One sheet or a large square on a panel will work 90% as well as covering the whole panel. The purpose of this is to dampen vibrations. It is not sound deadening mat, despite being labeled as such. For proper sound deadening you need something to isolate the sound. This is usually closed cell foam, or something like carpet padding.

The Adhesion works very good. The noise canceling I would say has dropped the decimals being picked up from outside of the car and I would say holds in more bass. It’s almost like insulating your car lol, this item requires you to take most of the interior out of your car to install this item. Overall rating 5/5 I would highly recommend this item for noise cancellation.

This stuff really worked great. Easy to install/apply and is an amazing product for the price...

Good adhesive works better than I expected

Great stuff. Easy to apply and was able to cut easily. Be careful when applying with your hands. I forgot how sharp the foil can get and sliced my finger.

I installed this KilMat in my 2015 Dodge Challenger, with ease. The whole trunk, wheel wells and Drivers side door. The hardest part was taking everything apart. Didnt use the roller, that much, could easily press everything down with your hands. The 50 sqft was more than enough to complete this job. The noise cancellation level was very noticeable, took out the rattle in the drivers door, now have to put a few strips on the rear deck, to quiet that down. Would recommend this to everyone, nice weekend project.

The road noise and overall tinny sound of closing the doors, trunk, etc. on a 2008 Accord Coupe got me to searching for a solution. Installed this stuff everywhere - on the floor, inside the doors, inside the trunk, on the ceiling, and on the rear-fenders (from inside; theres an opening under the trim). We also added Noico adhesive foam to further control road noise. It made a huge difference and the car is much more pleasant to drive on the highway now. Also, closing the doors now makes a reassuring, solid thump. Note: Handling the headliner to remove it killed the foam under the cloth. :-( 11 years of baking under a black roof, in the Texas sun, had weakened the foam. It crumbled from the handling and the liner started to sag in just a couple of days. Ugh! Pulled out the headliner and had it recovered at a local shop. Had I known this was a possibility, I might have left the ceiling alone! That ended up costing an extra $125 ($250 if the shop also did the remove and install of the headliner).

It removed almost all of the resonances inside my TrailBlazer SS and quieted the ride overall. I did use two boxes to get everything, including the inside of the car roof and inside wheel wells and door banels. Lining the overhead made a huge difference, I definitely recommend doing this. My AC seems to work so much better now and the car just does not get as hot inside, at least not anywhere near as bad as it used to when left sitting in the sun all day.

2006 Dodge Charger Trunk Easy to install with the self adhesive. Use a roller to make sure its applied correctly. Live in Hawaii where its 85⁰ out. Went on easy, easy to cut, trim and mold around all the joints. Sound test after and the obnoxious rattle from the sub is gone. Used 1 box of the 50 sq ft 50mm Kilmat, completely covered the Trunk and 2 or 3 layers in trouble spots. Definitely going to be ordering more.

Seems like it works. Did not check with a meter before or after but I feel as if the difference is somewhat minimal. I decided to buy and install this stuff on a Class C RV cab because of the intense amount of road noise. I realize that an RV is a moving house on wheels and will make all kinds of noise, but I really couldnt have a conversation with my wife when driving without yelling or hear the radio. I found killmat and decided to tear everything out and install these mats on doors and floors. I already had heat/sound resistant material in the doghouse from a previous install and do NOT recommend using this stuff in that heat. Post install drive seems like it reduced noise about 15 to 20 percent. Enough to have a conversation without yelling. My wife and kids say that they can tell the difference but Im a little more critical of my work. I also swapped out the crappy ford speakers with better speakers and can hear the radio fairly clearly. The difference is NOT night and day...it is more like night and early morning. It works but this is still an RV. It may work better in a regular vehicle. Was it worth all of my sweat to install...yeah, I think so.
