Our take on the Dynamat 10435 Xtreme Door Kit

Dynamat Door Kits put up a sonic barrier that keeps noise out and your system's sound in. That means you'll hear more music using less power — effectively increasing your amplifier's output.

Dynamat Door Kits put up a sonic barrier that keeps noise out and your system's sound in. That means you'll hear more music using less power — effectively increasing your amplifier's output.

High-performance Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. At .044" thick, it's lighter than Dynamat Original, four times more effective, requires no heat to apply and is recommended for contoured vehicle panels. Dynamat Xtreme is coated with aluminum to make it ideal for high temperature areas such as firewalls and floors - and for high SPL environments.

Contains four 12" x 36" sheets. Warranty: 60 days.

It helped the speaker sound and clarity and cut down on road noise, but it doesn't eliminate it. It's very easy to apply. Warning, wear gloves, as the surface is similar to foil and cuts skin easily.

Hands-on research

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: The rubber layer of Dynamat Xtreme is very sticky, so it comes with a peel-off paper liner. Once the paper liner is peeled from the rubber layer, Dynamat Xtreme can be adhered to your door panel.

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


Installation Steps:

  • Clean mounting surface (bare metal)
  • Using a razor knife or scissors cut Dynamat Xtreme to the desired size
  • Remove the blue 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
  • Work air out with a roller tool (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?

issues with road and tire noise in my SUV. [ L  Apr 11, 2017 ]
Quiet ride equals nice ride, like crutchfield product selection. [ Leonard  Apr 02, 2017 ]
To protect the speakers and to reduce road noise. Most of my driving is at highway speeds. [ Kaye Lorraine  Mar 17, 2017 ]
better sound quality [ Michael  Mar 04, 2017 ]
Can never have enough. Not the cheapest but I believe it's the best. [ Aaron  Jan 30, 2017 ]
Needed more for my Vehicle [ Rodney  Nov 22, 2016 ]
Needed fitted door sound dampened. [ Alexander Pike  Oct 16, 2016 ]
This stuff is great in cars, but did you know it works great in other places, too? I am putting a bunch of this along a long A/C duct run in my house to minimize vibrations. Heck, if there's any left over I'll just put it around my door speakers in the car. So many uses for this stuff. [ ZACHARY  Oct 03, 2016 ]
This was recommended by my professional installer. [ JOHN  Sep 15, 2016 ]
to help sound proof doors [ B  Aug 06, 2016 ]
to get better sound in the Rav4's tinny doors [ Joseph  Jul 23, 2016 ]
awesome stuff, makes great speakers incredible! [ KRISTOPHER  Jul 22, 2016 ]
Always been a fan of Dynamat to help the sound quality of any system installation. [ Mandel  May 29, 2016 ]
You want to limit the noise to what your speakers produce not the vibration of the door or whatever its mounted to. Order it. [ Christopher  Mar 10, 2016 ]
great product [ david  Mar 09, 2016 ]
I have used this item in previous installs and wouldn't install door speakers without it. [ Steven  Jan 19, 2016 ]
Dynamat has had a good track record and it did a great job at quieting resonance in previous cars I've owned. Compared to the basic dynamat that apparently isn't available anymore, it's much lighter. I had remnants of dynamat and dynamat xtreme, and 9 years later the xtreme is still a usable product whereas the basic stuff hardened up. Second Skin Damplifier was my other choice but it was a hassle for shipping to my location. [ Mark  Jan 18, 2016 ]
To lower outside noise. [ bill  Dec 15, 2015 ]
This stuff is excellent, but pricey. My recommendation is to buy the bulk set - if you want to cover bigger doors (my application was for a four-door Ford F150), you'll actually be short a bit.... Shockingly good effect! [ WILLIAM T  Dec 09, 2015 ]
I used it before and enjoyed the easy of installation. This is the largest kit and offers the most square footage. [ Damon  Dec 07, 2015 ]

It adheres to the inside of your doors, body panels, floor boards, etc. and it deadens road noise and reduces vibrations from a myriad of different sources. It helps get more of your music get to your ear, instead of getting lost or going elsewhere! [ Jeff  May 30, 2016 ]
It not only reduces vibrations but gives a sound barrier (keeps the outside noise out and inside noise in) works well, be thorough when putting in for best results but even a little helps. I installed on my 75 dodge truck doors and it helped a lot. I'd like to do more in the cab since its all just metal [ brian  May 30, 2016 ]
IT makes a huge difference.. Did my trunk and two front doors.It's a lot of work. But it is Worth it. If you are going to keep your car that is. [ Preston  May 30, 2016 ]
I installed it on the driver's side door but haven't installed it on the passenger side. So, not sure if it has made a difference in the sound. [ Angel  May 30, 2016 ]
it works. it realy makes a difer ce in sound, if you apply it correctly. check the you tube channel of car audio fabrications. there are a cuople of tutorials on te best practices to install it [ Jaime  May 30, 2016 ]
Thanks for your question. The manufacturer lists it as 0.085" thick. Hope that helps. [ Kenny  Apr 06, 2016 ]  Staff
