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

This product was easy to use and to place. Make sure you get some type of roller with the purchase.

You get a lot for what you pay for. Noise is cut down by at least 60%. Highly recommended. Nice product. Will definitely use again.

I upgraded my radio in my 18 Ram Quad Cab. This is one noisy pickup. A lot of sound from the 6x9s was just being canceled out and over powered by the road noise. This makes the treble really harsh and piercing. I could barely get the eq to make up for the noise. I used 38 of 47 sheets on the doors of kilmat. The difference is night and day. The doors feel more solid. They are heftier. The noise reduction is enormously significant. The harshness to my music is gone and the mids and lows are very pronounced now. Ill use the other 9 sheets to put under the carpet where the downward firing sub is and the rest under the carpet of the front seats. Great product with a better value compared to other brands.

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

***update*** I updated rating from 1 star to 4. The smell was faint but did seem to go away. Car is in garage and hasnt been exposed to sunlight yet, but hoping there is no smell. So based upon reviews I decided to purchase the 50 mil x 50 sf package. My main concern prior to purchasing was a chemical / asphalt smell, and most people stated there was zero smell. Well, thats not true at all, there is an asphalt smell. I havent even peeled the liner off and I can smell asphalt coming off the sheets. After spending hours scraping off the old sound deadener and prepping the panels, do I really want to stick on this stuff? Also had a bad experience in the past using Fatmat about 10yrs ago, and that smell never entirely went away and was extremely strong after installation and actually gave me headaches for weeks. That purchase was also made based upon price. So now, trying to decide if I should send this back or not. Im leaning towards sending back, I cant deal with that situation again Id rather just spend a little more and get a real true high quality Butyl product instead of asphalt. You get what you pay for....

Best bang for your buck. At a fraction of the cost of name-brand sound mat, this is absolutely unbeatable. I appplied liberal coverage (~80%) in my daily driven Nissan Juke, and the difference is definitely noticeable. Drastic improvement in sound quality inside, and a pretty significant reduction in noise heard outside. I also applied some matting to the floorboards, door, and roof skins on my G35 which really only sees track days. I’ve had it in my G35 for several years now, and have seen no signs of decreasing adhesion. Bottom line: don’t spend more for a product that isn’t really all that much better, when you can have a comparable alternative at a fraction of the cost.

updated. i tried partial coverage. one box 50 sq. ft. and put it on all the biggest metal panels. it was somewhat effective but i was not 100% happy with it. for best results go full coverage. at least 90%. i keep buying more and tearing my car apart again lol! just buy 150 sq. ft. and go nuts and cover everything! not just metal, on the back of all the plastic interior panels too. put a couple extra sheets in the middle of big panels to double up. i have a big 4 door camry so a hatchback could do 100 sq. ft. you can definitely have too little. but you cant have too much! the more you put on the better it works! i will likely buy another box to do the hood and front fenders in the future. i also found that it works great inside plastic speaker enclosures around the house.

Works perfectly

The product quantity was more that enough to cover 4 doors on a 2008 Tacoma and still had enough to cover probably another 4, had plenty left over. Did install on a 85° day and they adhere really well. Tried using gloves but its hard, easier if you dont use them. It did leave a light smell of tar for a day or two only. The doors do feel as if they close tighter but didt really notice a great difference in outside backgound noise. Speaker sound does sound better. Definetly not to be used as insulation, they feel hot to the touch as metal does but still do recommend.

Supper easy to work with. I laid them on my driveway. So they can heat up with the sun. That makes it even more easy to install it. I didn’t like the roller I used a handle of a screwdriver. That helps out a lot for the thought corners. I have a 89 c1500 and the cab sounds solid now.I used a box and half for the entire cab. Ceiling, floor, under rear window, fire wall I did double the one on the floor.
