Description

Where can I install Dynamat Xtreme in my vehicle? How much material do I need? Dynamat Xtreme can be installed on doors, floors, trunks, roofs, rear decks, quarter panels and firewalls in cars, trucks, SUVs, classic cars and custom builds. To determine how much Dynamat you need, see our square footage calculator chart above. How much will Dynamat quiet my car? Even a small amount of Dynamat can greatly reduce noise. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB. Complete coverage of an average vehicle can reduce road noise 9, 12, even as much as 18dB. Is Dynamat Xtreme better than asphalt sound deadening mats? Dynamat Xtreme uses advanced butyl and aluminum construction that resists heat, odor and adhesive failure better than many asphalt-based sound deadening materials.

The butyl rubber core and protective aluminum foil layer make Dynamat Xtreme moisture-resistant and airtight – perfect for automotive and RV interiors and boat applications. Why should I buy Dynamat Xtreme? Got noisy rattles and hums? Inside of the car get too hot? Phone calls or music sound muffled and muddy?

    • Satisfied With the Results on my Jeep Wrangler
Style: Bulk Pack 36 sqft
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. ... show more

I recently purchased the Dynamat 10455 18" x 32" x 0.067" Thick Self-Adhesive Sound Deadener Xtreme Bulk Pack, which includes 9 sheets in black, and I couldn't be happier with the results. First and foremost, the sound deadening capabilities of this product are exceptional. I used it to soundproof my car's interior, and the difference is night and day. Road noise, engine vibrations, and rattles have all been significantly reduced. The improvement in cabin acoustics is noticeable, making for a quieter and more comfortable driving experience. The self-adhesive backing on these sheets is a game-changer. It made installation a breeze. Simply peel and stick, and the sheets adhere firmly to the desired surface. The flexibility of the material allowed me to apply it to various contours and shapes within my vehicle, ensuring comprehensive coverage. The thickness of 0.067" is perfect for sound deadening without adding too much bulk. It effectively absorbs and dampens vibrations without taking up precious interior space. In terms of build quality, Dynamat is known for its durability, and these sheets are no exception. They feel solid and are clearly designed to last, even in challenging automotive environments. While this product is on the pricier side, the results are well worth the investment. If you're looking to enhance your car's audio quality, reduce road noise, and create a more serene driving environment, the Dynamat 10455 Self-Adhesive Sound Deadener Xtreme Bulk Pack is a highly effective and quality solution. I highly recommend it to anyone looking to upgrade their vehicle's soundproofing. ... show more

    • Great stuff.. Buy more than you think you'll need!
Style: Bulk Pack 36 sqft
As others has said, I bought to improve sound and road/car noise for my '01 Miata. Got the 9 pack here on Amazon and installed last night. I recently upgraded my stock radio with a new head unit, Alpines in the doors and a Bazooka in the trunk. 450 total watts total. Love the improvement... but with a roadster, noise is a killer, so I broke down after much research and bought the Dynamat pack. So I started on the trunk and lid, fully lined single layer, did the inside rear quarter panels too. Could immediately notice the trunk sounded tighter, less echo. Took 2 hours of effort, but I had to use 5 sheets (18x32) and used a lot more than I thought for such a small trunk. Moved on to the interior with what was left. Pulled passenger seat, carpet and tranny tunnel and used 3 more sheets on floor and behind seat. I figured at this point, doing each area fully and getting more product to finish was wiser than trying to conserve and not getting everything done. Well after 4 hours, I ran out, without getting doors or driver's side, but after a couple test drives am pretty pleased with the results! Can only imagine the improvement when my next pack arrives to finish what's left. Will probably do doors double layer, maybe under the hood if I have enough left. Trunk is very tight, quiet on the outside and no vibrations Everything you've probably read is exactly correct. Clean first, roll on tight, seal well. I used the roller and a small rubber mallet to press and seal, the mallet was a big help, with the long handle to reach tight spots and really press down the material. Messy, sharp and sweaty work.. all true. But the results are well worth it. My car is considerably quieter, the music tighter, even without it all completed. All told, a couple hundred will go into the effort, about 8 or so hours to complete. This product delivers what it says, I highly recommend it! Be sure and get enough when you order, it will probably take more than you think, you'll find areas you hadn't thought of to cover, sometimes you'll want to double it up. I'll be at nearly 700-800 sq ft of product on a small Miata, a truck or big SUV will surely take much more. ... show more
