Dynamat Xtreme Sound Deadening Car Insulation Bulk Pack – Noise Dampening Kit for Floor, Doors, Panels, Hood, Engine or Trunk – Easy Self Adhesive Install – 9 Sheets 18”x32” Each, 36 sq ft total

I had never heard about this stuff: I have insulated doors & the boot floor of a Peugeot 107 & it makes a huge difference: It simply insulates your car, cutting out external sound that ruins your stereo listening & making all those rattly thin metal surfaces stop vibrating. It improves motorway driving by making the car quiet and far more relaxing to drive. It takes time to fit, is not cheap and does add weight to the car, but it really is worth it. Why pay for a louder stereo when this makes far more difference.

Speed of delivery, Very easy to use.A penknife, craft knife or scissors. The product is easy to apply and certainly cuts down on drumming. Expensive but probably the best. Well worth it.

I drive an 80's Toyota with a rather loud exhaust. I had seen Dynamat on Overhaulin with Chip Foose and decided to give it a go and I am very impressed by the quality, ease of fitting (except removing the seats etc from the car) and the difference it has made when driving, road and exhaust noise has reduced dramatically. It may be expensive, but in my opinion it is worth it.

Product as described, very robust, easy to work with in flat spaces, would order again

Sadly there are no detailed application instructions included in the box for some reason. It will definitely improve the acoustic quality inside the vehicle a lot. I do not believe you need as much as people think, although 1 box was not sufficient to do a complete large car inside (Doors, floor, boot, roof etc) Pieces are very large at 32 inches long, I think I would have been better off cutting them into smaller ones, as you can get yourself into a dire situation when its massive and its all sticking to everything including limbs and you are trying to fight it to make it fit correctly. Tended to feel that all the photos online of installations make it look super tidy and easy, and my install was more like a Mcdonald's burger, it never ends up looking like the photo. I could not decide if its better to try and measure and pre-cut templates, or just cut as you go along. Definitely found it more fiddly than I expected.

I needed to cure noise, vibration and harshness (NVH) issues with my car, and this stuff has exceeded my expectations. One trick worth knowing is to paint the surface(s) you want it to adhere to with a "high-tack" bitumen primer, available from most DIY outlets. This ensures that the Dynamat makes the best contact with the panels you're insulating. Cant' recommend this stuff highly enough - it's not cheap, but then quality usually isn't, is it?

Now my Bose sound system car sounds like it should! Also, made the car a whole lot quieter and feels more refined, particularly on motorways.

Good product it does make a difference to my car easy yo apply and cut

Graet Product Ever!!!!.....

Dopo tante ricerche ho deciso di scegliere questo prodotto per le ottime recensioni, e con l’acquisto del set da 9 foglii ed ho insonorizzato 4 sportelli dell’auto e mi sono avanzati 2 fogli. Il risultato di diminuzione del rumore è percettibile già ad orecchio, ma andrebbe verificato precisamente con un fonometro. Tuttavia l’acustica del suono degli speaker è migliorata tantissimo che già con gli altoparlanti di serie il risultato era nettamente superiore. La mia auto è di buona qualità e già abbastanza insonorizzata ma il miglioramento è evidente. Molte meno risonanze alle basse frequenze, un basso più nitido e corposo. Lo consiglio davvero, non avrei immaginato. La spesa è stata alta, ma ne è valsa la pena. Grazie Dynamat

Overall, I am very satisfied with Dynamat Extreme. My attempt was to quite the road noise in my Jeep Wrangler with 39” mud tires. After many wheeling trips having to wear hearing protection (especially driving back from Moab to the east coast) and trying to save what little hearing I have left, I decided to try Dynamat and reinstall the carpeting and see if the dB level goes down significantly, maybe even enough to be able to hear the radio and CB while moving at highway speeds. So far, I am impressed with the results. They are not spectacular but there was a lot of noise to knock down. For Jeep owners who might be considering buying Dynamat, here is what I did as an example. I pulled the floor mats and seats then installed it from the firewall back to the rear gate. I overlapped a bit on the firewall, tunnel, front floor boards, and rear fender wells, and also cut out around the drain plugs and taped them off. I reinstalled the factory carpet, front to rear, and will just deal with pulling it and spraying out the mud and dirt once in a while. I reinstalled the factory plastic pieces near the back of the gate (2015 Jeep) but I used a lot of scrap pieces to stick to the backside of the plastic to deaden the hollow, cheap sound. This actually worked really well! I have MOPAR half doors which sound pretty hollow, especially with the factory plastic interior pieces. I disassembled the doors and lined as much as I could on the outer skin of the door, then stuffed a lot of Pelican case pick and pull foam that I cut to fit snuggly inside the door, especially across the “safety bracing” inside the center of the door. After that, I lined the rest of the exposed metal areas of the inner door skin and also stuck the scrap pieces to the plastic interior piece, specifically around the handle area and in the lower section of the rear door panels (you’ll see what I mean when you disassemble the door). All of this on the doors made a dramatic change in the door clunkiness and made another significant change in the road noise level. Additionally, when I close the doors now it sounds way smoother and will make you question whether you closed it hard enough to latch shut. Knocking on the outside of the doors sounds much more dense. For a four door JK, I used two nine packs of 18”x32” Dynamat and two rolls of tape. I ran out of tape and used aluminum tape that one would use on an HVAC unit, I just cut the two-inch tape into one-inch wide strips to finish the job. As I mentioned earlier, I did overlap a little, but not very much so I would definitely suggest two boxes for a four door Jeep. As for the radio quality improvement (taking into consideration the NON-Alpine stereo and soft upper half doors) the stereo sounds surprisingly better while parked. The volume at 20 is clearer and louder than it was at 28 before. On the road doing 60 mph, I can actually hear the radio clearly at 18 and it sounds good at 22-24. Before installing the Dynamat, the volume at 22-24 was overpowered by the tire, wind, and road noise. We are going on a wheeling trip this weekend, so I am hoping that I will be able to hear my CB on the highway! In summary, I am satisfied with the results for my purpose. I have no doubt that someone with a normal car who is looking to quite road noise and improve stereo sound would be especially satisfied and impressed with the change.

Producto top, caro pero impecable. Muy fácil de aplicar, se amolda muy bien.

Le da más solidez a la lamina, un poco complicado para instalar en partes curvas, pero en general muy bien
