KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Good quality. Easy to cut, easy to apply. Rolls on easy. Good adhesive. Lowered the cabin road noise in my Mustang and lowered the cabin db of the exhaust. Installed with a full custom audio system. Would purchase again.

So if your buying this, you're either killing road noise in your vehicle, or installing a sound system in a vehicle. Let me start buy saying...is it as good as Dynamat? No. Its not...BUT.....please continue reading. Dynamat, at the time of this review, is 5x the cost of this stuff, and its NOT 5x better. its only VERY slightly better. And honestly, BOTH are Butyl Rubber, so the only thing that makes the dynamat better, is its a hair thicker. I bought 3 boxes of the stuff for around half the price of 1 box of Dynamat, and I would do it again. I am building an older mazda truck, and I put 1 layer on the inside of the door skins and roof, 2 layers on the back wall, and 3 on the floor and firewall, and its SILENT inside the truck. It stopped ALL the vibration, sheetmetal reverberation, and the drum effect from thin sheet metal. Its nice and thick, it cuts easy, and sticks well. A couple of pointers before you install it.... Vacuum out all the dust. you want the best possible contact from the rubber to the surface of the panel. Get the installation roller. You can do it without it, but it makes mashing it down a lot easier. Don't waste time fitting it like a jigsaw puzzle. I was trying to do that because I assumed it would give a better end result, until my audio installer friend came over and just told me overlap it and call it day. Its getting covered with panels, and the more weight from the deadener the better. Ended up taking all the little cut parts and sticking them on the firewall. This stuff doesn't look, feel, or act like a cheap "store brand knock off". Get a box and try it before you spend a fortune on "name brand" stuff that is the exact same material with a different logo. Highly recommended. Will buy more if I need it in the future.

Really good product for the price, I used it on the doors in my 2008 civic SI. It sticks really well and does a good job of deadening vibrations and adding mass. It forms to things and cuts well, but still holds enough of a shape to not seem floppy or cheap. The doors seem a lot more solid and sound good when they close compared to before.

I originally didn’t plan on doing any modifications to the car at all 😅 But my factory driver-side speaker finally blew, and since I already had to remove the door panel to install a new speaker, I figured I might as well add some sound deadening while I was in there. I used 4 sheets total, covering roughly 80% of the easily reachable areas — probably around 70% of the entire door overall. The front door now feels noticeably heavier and more solid. When knocking on it, the sound changed from a hollow “tin can” echo to a much more muted, premium thud compared to the rear door. Even opening and closing the door feels quieter and deeper now. I’ve only done the front driver-side door so far, but the improvement is already super obvious. Definitely worth doing if you’re replacing speakers or just want the car to feel a little more refined overall.

Sticks well. Not as nice as Siless version. If I were buying again I would just buy extras Siless 120 mil, they are around the same price but the value is better with Siless's thicker panels even though you get less total coverage per pack. Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesn't smell hardly at all while being applied and once its on there is no smell whatsoever The product is good for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.

I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Great stuff. Use this in conjunction with the foam. My truck sounds like a luxury car. Buy more than you think you will need. It goes very fast. I have ordered several times and I still need more. It’s ok to cut. Use a razor blade to make it easier. Sticks very well. Overall I’m happy to have used this. The sound in the truck is very quiet. It’s a newer truck but they aren’t made the same as they used to be. Another benefit, the speakers are more clear too. Great purchase!

I used this in my 2rd gen Cummins. I had always heard about the added weight and whatnot (not that it matters in a diesel truck), but it wasn't overly heavy to me. I did a crew cab truck with 1.5 boxes, so the coverage per box is solid. It's easy to work with and adheres very well. I can tell a big difference from the cab drone now vs before, also a lot less rattles and shakes. Very glad I decided to do it.

Muy práctico fácil de instalar, fácil de cortar, tiene muy buen peso se aprecia de calidad, el adhesivo pega muy bien ya instalado le da fortaleza y cumple, muy recomendable

I purchased this for insulating both my door panels and the back of the door cards during my audio system install. I'm no expert, but this product was easy to cut, easy to install and had noticeable results. Road noise was reduced vastly, which was the main goal for this project.

Werkt goed & plakt goed. Doet wat het beloofd

Excellent

El producto es bastante bueno y a un costo razonable aunque comparándolo con el mismo producto marca de Amazon es superior y más resistente el de Amazon aunque esté cumple con el objetivo, creo si reune las 3 b de bueno bonito y barato, sin duda lo volveré a comprar
