Having a hard time hearing your car's sound system over the road noise? Dynamat Xtreme keeps the noise out, so you'll hear more music using less power — effectively increasing your amplifier's output! This sheet metal vibration damping material (a butyl composite with a layer of aluminum) conforms and fuses to automotive body surfaces such as floor pans and doors.

The 10455 bulk kit includes 9 sheets of Dynamat Xtreme, for a total of about 36 square feet (a car door requires about 5 square feet). Designed especially for high-temperature areas and high sound pressure level situations, Dynamat Xtreme offers four times the damping power of Original Dynamat, thanks to its energy-reflective aluminum layer. Warranty: 60 days.

Features

Dynamat Xtreme: Dynamat Xtreme provides 4 times the damping efficiency of Original Dynamat, the conforming ability of Premium Dynamat, and the radiant energy reflection of Super Dynamat. Dynamat Xtreme has an aluminum layer for high-temperature areas and requires "no heat" for an easy, moldable installation.

Self-Adhesive Sheets: Each sheet has a high-tack permanent adhesive with a peel-off plastic liner on the back of the Dynamat Xtreme.

Easy-to-Cut Materials: All materials cut easily with scissors or a razor knife.

Installation

Basic Installation Steps:
  1. Clean the mounting surface.
  2. Using a razor knife or scissors, cut the Dynamat to the desired size.
  3. Remove the blue release liner from the back of the Dynamat and apply to the mounting surface.
  4. Apply pressure, working the Dynamat into the contours of the mounting surface.
  5. Work air out with a roller tool (eliminating air pockets will ensure lasting adhesion of the Dynamat to the surface, giving you maximum damping effect).
  6. Repeat the same process for each sheet of Dynamat.

Dimensions

  • Each Sheet: L=32", W=18", Thickness=0.085"

Good Stuff

Written By Johnny, Deltona, FL on Monday, October 06, 2014

Crutchfield Customer Review (What's this?)

First of all I want to clarify some things that I had read on other reviews of this product. First of all you don't need gloves, this stuff is too sticky for gloves. Second they recommended that you get the roller, I purchased the expensive one and really did not have much use for it so don't waste your money on one. I found that I had better luck just using a metal spatula like the ones you use to spread plaster. I used a 3" and a 1.5" on tight spots. You hold the spatula with one hand and put pressure on the metal part of the spatula with your other hand as your flattening the sheets and you use your fingers too where it's more contoured. I made the large cuts with a razor knife and the smaller cuts with a pair of scissors. I thought I was going to able to do all of my extended cab Colorado with this box but all I was able to do was the four doors, two regular doors and the two smaller ones. I have a little left to put on the floor pans but not enough to cover the whole floor. I wish I could have been able to do the entire floor of the truck. If you purchase this product thinking you can do the trunk and all the doors you are going to be disappointed. I think if you want to do the 4doors and the trunk you will need two of these boxes, if your going to just do the doors you'll be okay or if your planning on just doing the trunk you'll be okay. When I first looked at the Dynamat Extreme I was not impressed but after installing it I was impressed, just wish it was cheaper.

Pros: Good quality product, very sticky but easy to use after you get the hang of it.

Cons: Not enough material for the price, too expensive.

great sound

Crutchfield Customer Review (What's this?)

This is the first time I used the product and strongly recommend using it for an upgrade to any stereo. With a quieter ride and better sound from the stereo system

Pros: great sound, and quieter ride

Cons: I couldn't talk anyone of friends to install it for me

Expensive

Crutchfield Customer Review (What's this?)

The product is great. I've used Dynamat for years.

Cons: Price on Crutchfield

Big difference

Written By Ivan, PA on Thursday, April 29, 2010

I have a 2003 Corolla S and there was plenty of dynamat to cover the trunk with. It took about 3 hours to install and the edges are sharp I found that out the hard way. I used the dynamat rubber roller it helped make it easier. The trunk barely rattles compared to before.

Trunk Pack

Written By Anthony, Philadelphia, Pa on Monday, August 17, 2009

I purchased a Bulk Pack with the intent to deaden my Trunk and Front
Doors; however I used 98% Bulk Pack in my trunk!!!! I drive a "07" Grand
Prix and can honestly say that I either did the install wrong or "Over killed
the project"

Tools-
Alcohol
Razor
Wipes
Heatgun (Not Necessary but just because)

I started my project off by vacuuming the trunk and then with 91%
alcohol. I then let it dry and started to do the lid of the trunk. I removed the
carpet and applied single layers very neatly. I then started to do the wheel
well and floor of the trunk working around the fuel pump and all the way
back to the seats. By this time my trunk was 99% dynamated!!! :) With the
last sheet I sliced it up and applied it to the pillars of the car. (Front/ Rear
Windshield).

My only downfall with the installation is that I should have applied some
to the back of the License plate and under the spoiler.

Hands down the dynamat is a excellent product.

PLEASE, PLEASE wear GLOVES!!!!!!!!!!!!!!!!!!!!!

Crutchfield Customer Review (What's this?)

This product is great. Is not that hard once you learn to work with it. Is very sticky and sharp on edges (wear gloves to prevent cuts). The roller tool is a must if you are a first timer like me. I made paper templates of the areas I wanted to cover and then cut the Dynamat from them. It made the job a lot easier. The difference in noise and vibration dampening is huge. Music hears a lot better now, and the road noise reduced. I installed 2 bulk boxes and a trunk kit. I have a 2007 Tacoma access cab and I practically covered the whole truck, doors, roof, floor and back panel. It took me 2 days to install everything. If you feel comfortable taking out all seats,carpet, door panels, roof panels, interior panels, then this is a relatively straight forward project. I highly recommend this product.

Wow ... What a Difference

Written By winkle74, Knoxville, TN on Sunday, July 20, 2008

I own a 2001 Nissan Xterra. These vehicles are very noisy. I purchased 2 boxes.

Day 1 - I started with the front doors - then moved to the passenger doors - next moved to the rear panels. I still had a lot of sheets left and decided to cover the entire cargo area. Once I finished, I got in the car and took a drive. I immediately could tell a huge difference! Since I had another full box I decided to do the floor.

Day 2 - I didn't cover the entire floor. However, I would say 95% of the floor is covered. I put everything back in it's place and took another test drive (both test drives included the highway). All I can say is WOW! I'm absolutely blown away by this product! I don't have to turn the volume up on my radio to hear it! The stereo sounds 10 times better (which I just installed a new JVC head unit with new Alpine speakers). This stuff probably cut about 70% of my road noise.

It does have sharp edges ... but if you take your time and keep this in mind, then you won't have any issues. I have 2 small, paper cut like cuts and that's it. It is also heavy ... so keep in mind you're adding some extra pounds to the car ... The label on the UPS box say one box weighs around 23lbs.

Been using Dynamat for years

Written By Robert, Garner, NC on Monday, May 26, 2008

I have been using Dynamat since it first came out. To me, there is nothing
else close to it. Lot's of copycats, but nothing as good.

I bought two bulk packs and 4 door kits for my 1996 Dodge Dakota truck.
Yep, it's a knockaround truck--but I like my music. The truck itself was very
loud. Just driving down the road my wife and I could hardly have a
conversation. So, I took out the seat, and the carpet. I put a double layer
of dynamat on the floor, the back wall, and inside the rear speaker wells.
You can just peel and stick the extreme down--but I always heat it up with
a heat gun and roll it on---it DOES make a big difference.

After that, I got some Herculiner roll on bed liner. I put two coats of that on
over top of the dynamat. Then I bought a quart of black rust-o-leum
hammered finish paint--and put two coats of paint on top of the herculiner.
Then I put the carpet back down and instaleld the stereo.

Needless to say, the silence is incredible. If you truly want a quiet ride, and
a quick upgrade on your sound system---get some dynamat---you will not
be sorry.

works good

Written By Mark, medford, ma on Sunday, June 11, 2006

i got a dynamat extreme bulk pack and i applied it all in my trunk. 36 sq feet just about did it, but i have 2 door with a medium size trunk. this stuff eliminates probably about 80% of the rattles that my subwoofers caused. but the thing i like best is how it made the subs LOUDER and the bass CLEANER. it really keeps the bass in and reflects sound good. dont expect it to eliminate your rattle completely. if you have two 200 rms subs, your prolly not gonna get any rattle, but if u have two 500 rms subs, your gonna get some. good product deffinitly worth the money

Written By mike, Glasgow Ky on Sunday, July 17, 2005

This stuff is a must esp. if you own a truck with an exhaust system like i do its a little time consuming but well worth the effort if plan on putting any money in your system spend the extra cash and the extra time to install this you ll be glad you did
