Dynamat Xtreme Sound Deadening Car Insulation Single Sheet Hex Pack – Noise Dampening Kit for Floor, Doors, Panels, Hood, Engine or Trunk – Easy Self Adhesive Install – 1 Sheet 18”x32”, 4 sq ft

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.

Worked fantastic. No more rattling in the trunk . I couldn’t believe it . No more noise . Worked great easy to apply

I bought two boxes of the 18/32". I covered 100% of my entire floor pan and rear wall in my 2012 Tacoma and still had 2 and half sheets left. My tires are the BFGoodrich All Terrain KO2's, which make it difficult to have medium volume level conversations at 65 MPH. After installing the Dynamat, I'm now able to have more comfortable conversations on the HWY and softer conversations on surface streets. It not only made a difference in attenuating road noise, it increased the bass response in the cab, so much so, that I had to turn the Bass EQ down. I even notice the bass in my voice was more apparent. The reduction in road noise did not bring it down to luxury level, but as a truck owner with off-road tires, it's a welcome upgrade and well worth the money. It took two, six hours per day to complete with two people doing a premium job. Don't forget to pay attention to the bolt hole...lol FYI: The metal rollers, 1.0 and 1.5 work best. Those green rollers are lighter, so you have to press a little harder and they as so, don't grab the Dynamat as well.

I agree with the others; anyone who doesn't like this product must have installed it wrong.I have a 2000 Honda CR-V SE. I lined the underside of the hood, the entire roof, all four doors (inside the doors and the surface), much of the floor, the spare tire well, the rear quarters (inside, behind the rear speakers) and lots of the tailgate with two (2x) Bulk Packs (9 sheets each.) I had not planned to line the roof, but after gutting the seats, all trim panels, and all the carpeting it seemed worthwhile. I cannot explain how differently the vehicle sounds now. EVERYONE compliments it (including my wife, who could not understand why I was spending the time and money on the project in the first place, but now wants me to Dynamat her Solara!) The doors go "kfump". Knocking on the hood, roof, or doors sounds like hitting a solid wood desk. There are NO vibrations or rattles in the car whatsoever (I also got some cheap self-adhesive felt sheets from a hobby store and lined the ashtray, glove box, and little change compartments. Now it's like driving around with ear muffs on. There is still some road noise, because I have pretty knobby tires, but the incredible thing is that I can no longer hear my exhaust from the rear of the car, and sometimes I'll look sideways and notice an 18 wheeler beside me that I did not even hear. When I pass vehicles going the opposite direction I am used to the "whee-owwww" as they go by, but now it is a "whiff", or just silent.Lining the roof made a huge difference when driving in the rain, but since the windshield is so noisy in a downpour the cabin is still pretty loud, but there is no "ratta-tat-tat" from the metal anymore at all.I bought a heat gun and the rubber Dynamat roller specifically for this project (though I'm sure I'll get plenty more use out of the heat gun). I agree with many of the other reviewers that if you do not press this stuff down in FIRM contact with your vehicle that you will not get the best results. I've done MUCH (much, much, much, much...) research on this and the bottom line is that this product is so effective because of "vibration damping", NOT sound blocking. If you hold a sheet up in midair between you and a speaker it will have no effect. If you glue it to the speaker you will virtually stop the sound.I can also go on about how AMAZINGLY different that my stereo sounds, but I think everyone else covered that. Yes; more mid-bass. Yes; you will hear things in your music that you never heard before. Something that surprised me though was how much quieter your music is OUTSIDE your car. I am not a loud person, and I always turn the volume down at stop lights, and in residential neighborhoods, but one time I stepped out of my car and left the stereo on at a pretty comfortable level. When I closed the door I could not hear it at all. Nothing. Nada. That was a nice bonus.This stuff is incredible when installed right. Amazon had the best prices in all my searches. You will ache, you will probably bleed, but a weekend or two of hard work should reward you for years. Enjoy!
