About the Dynamat Xtreme Wedge Pack

You've installed speakers and subwoofers so you can hear clear, vibrant music in your car. Why put up with road noise? Dynamat Xtreme Wedge Pack minimizes your car's irritating resonances and screens out noise from the wind, your engine, and surrounding traffic, all factors that can jeopardize sound quality.

You've installed speakers and subwoofers so you can hear clear, vibrant music in your car. Why put up with road noise? Dynamat Xtreme Wedge Pack minimizes your car's irritating resonances and screens out noise from the wind, your engine, and surrounding traffic, all factors that can jeopardize sound quality.

Dynamat designed this self-adhesive Xtreme sheet for general use on rear decks, doors, floors, and trunks. Apply this sheet to a car door before mounting a speaker, and you'll transform flimsy metal into a solid, non-resonant baffle. Unlike Dynamat Original, you can also install Dynamat Xtreme on trunk lids, roofs, quarter panels, and even under your car's hood. And Xtreme proves four times more effective than Original in reducing noise, so you'll hear your music and nothing else.

One 32" x 18" sheet, 4 square feet total. Warranty: 60 days.

More details on the Dynamat Xtreme Wedge Pack

Product Research



Overview: Dynamat Xtreme provides four 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. Dynamat Xtreme will create a seal and damp the door panel to maximize your system's performance.

Self-Adhesive: There is a high tack permanent adhesive with a peel off plastic liner on the back of the Dynamat Xtreme.

Easy to Cut: The material cuts easily with scissors or a razor knife.


Installation Steps:

  • Clean mounting surface (bare metal or fiberglass)
  • Using a razor knife or scissors cut Dynamat Xtreme to the desired size
  • Remove the release liner from the back of the Dynamat Xtreme and apply to door
  • Apply pressure, working Dynamat Xtreme into the contours of the door panel with a roller tool
  • Work out air pockets (eliminating air pockets will ensure lasting adhesion of the Dynamat Xtreme to the panel, giving you maximum damping effect)

Customer Q&A

Crutchfield asked: Why did you buy this?
this product is just awesome, deadens everything. [ David  Jun 12, 2019 ]
Prevent Vibration and improves sound quality [ FRANK R  Dec 18, 2018 ]
Needed enough sound deadening for 4 speaker openings, and one pack of this was a better deal than 2x packs of the 10" x 10" sheets [ EVAN J  Nov 13, 2018 ]
better sound [ Bryan  May 03, 2018 ]
I hope to install this material on the metal frame behind the kick panels of my 1968 Cougar. I am installing 6 1/2" speakers in custom aftermarket kick panels to put speakers where they never were intended. [ John  Apr 24, 2018 ]
I have a Rockford Fosgate Punch sound system in my Toyota truck that sounds awesome, however there are a bit of plastic components inside the truck that rattles a bunch and ruins the sound quality a quite a bit. I'm hoping that the Dynamat will help drastically reduce or even better, eliminate, the rattling. [ Anthony  Mar 21, 2018 ]
Good stuff [ Jonathan  Mar 20, 2018 ]
Sound deadening for the doors. [ DONALD  Mar 17, 2018 ]
Going to upgrade the cotton like sound deadening on my door panels. [ Gabriel  Mar 17, 2018 ]
I have some resonances coming from my driver side door and I'd like to try using this product to get rid of them. [ James  Mar 16, 2018 ]
Because I hate listening to rattling after hooking up a nice system [ Joseph fuller  Jan 06, 2018 ]
this was over a year ago for my car speaker [ Hal  Jun 21, 2017 ]
Adding a lot more power to my door speakers so I will need to deaden the door cards heavily to prevent rattling. [ John  Jun 18, 2017 ]
I read the reviews. Even though this product is a more money than the other products out there, it seems to be thicker and people claim that it does what was designed to do. I will let you know once I install it. [ Timothy  Jun 09, 2017 ]
Kevin steered me to this instead of 2 10x10 door sets. This set has more material and is actually cheaper than 2 of the 10x10 sets. Saved me over $10. Thanks Kevin! [ Scott  Jun 02, 2017 ]
Really tightens up and adds mass to my kick panels, helps midbass performance immensely. [ KENNETH  Feb 20, 2017 ]
improve speaker sound [ Karl  Dec 29, 2016 ]
Great product. Installing speakers and needed the extra size to make a custom enclosure work. [ Thomas A.  Nov 12, 2016 ]
My trunk raddles like crazy! [ Giovani  Oct 25, 2016 ]
To make sure that my trunk does not fall apart. [ Anna  Sep 10, 2016 ]
Choice this to make the install perfect after reading other comments. [ abfisch  Aug 28, 2016 ]
For less vibration and durability on the install. [ ANDRES  Jul 12, 2016 ]
needed to replace rotted, water soaked original equipment sound deadening in 2002 Avalon [ James  Jun 19, 2016 ]
Right size for rear deck. [ Maverick  Jun 08, 2016 ]
This product provides enough Dynamat product to cut into squares to apply to my trunk lid and other areas. Great idea when adding a sub-woofer to stop rattle from trunk lid and more. [ Barrett Hall  Feb 18, 2016 ]
Dynamat has a good reputation and the piece will be big enough [ Steve  Feb 08, 2016 ]
Reduces the vibrations. I wasn't sure how well this would work but I have no doubts anymore. [ Paul  Dec 18, 2015 ]

3 questions already asked

Will this affect anything with side door airbags if I place some on the inside door skins as well as the panels?

This will depend largely on your vehicle. For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation.
[ Kenny  May 09, 2017 ]  Staff
Hi. I live in an apartment with metal doors. The doors are where most of the neighbors noise is getting through. I'm thinking this will help considerably. Do you?

I'm sorry but I have only used this product in my Jaguar XK8. It works wonderfully in this particular application.
[ ROBERT W  Apr 10, 2016 ]
Absolutely it dampens a lot of sound and vibration.
[ RICARDO  Apr 10, 2016 ]
is this self-adherent or do i need finishing tape?
[ C.Castro  Jan 02, 2014 ]
4 answers
Self adhesive, and works great!
[ ANTHONY  Jan 04, 2014 ]
No tape needed. I use a heat gun on the lowest setting and it did the job
[ FERNANDO C  Jan 03, 2014 ]
The material is self adhesive and can be easily cut and fitted. A hand roller is recommended to make good adhesive contact eliminating air bubble entrapment. A strong pair of upholstery shears or scissors works well for cutting and trimming if required. Do most of your cuts and fitting before you remove the protective adhesive backing for the final application, repositioning is next to impossible without damage once it has been installed. After you make cuts foil backing will have extra sharp edges in those areas and gloves should be considered to prevent injury. Finishing tape is not required but can be used on seams or overlaps if desired. It is a great product that conforms to odd shapes and works as it is designed too.
[ SCOTT  Jan 03, 2014 ]
Its self adherent
