About 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.

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.

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

Would only 1 of these door packs be enough to do all 4 doors of my 2007 Dodge Dakota?
[ Anthony  Mar 18, 2021 ]
1 answer
Possibly. I did the four passenger doors of a minivan and had some dynamat left over. I recommend measuring the interiors of the Dakota doors and using these numbers to calculate the absolute maximum surface area you may have to cover. The actual area you will be able to cover will be smaller because of hardware inside the door and the inaccessibility of some locations. Compare this total area with the 4x12x36 = 1728 square inches of dynamat in the package to see how much dynamat you may be over or short. Even if the dynamat comes up one or two hundred square inches short of your calculated needs for the entire job, you probably will be OK. First, remember the inaccessibility mentioned earlier - that will free-up some dynamat for other locations. Second, the shortage is spread across four doors (i.e., 200 square inches total is 50 square inches per door), If you cut and place the dynamat such that the metal left uncovered is at the perimeter of the door, you will end up with a strip of uncovered metal that is perhaps one inch wide. Since the uncovered metal is at the edge of the door, you probably will have achieved your sound-deadening goals. BTW, Crutchfield's interior panel removal tools were worth the money - they made panel removal easy and scratch free. Patience and good luck!

God bless you, I installed it in my ford explorer and it took me about 3 hoursEnter an answer to this question.
[ agustin  Oct 15, 2020 ]
depends on where you're going to install it and how long it takes you the panels to take off on the car The installation of the product itself should be no more than 15 minutes
[ PAUL  Oct 15, 2020 ]
My stereo guy did all 4doors in my 4runner did not take him that long and sounds awesome also changed out all 4 door spkrs 2008 4runner
[ LEWIS  Oct 15, 2020 ]
It depends on a lot of things but after 1 hour you're just getting started
[ KENNETH  Oct 15, 2020 ]
It really depends mostly on how long it will take you to remove your door panels and any linings specific to your car. Once you have it down to bare metal these sheets are pretty much peel and stick. So the bulk of your time will be removing and installing your interior panels.
[ Christopher  Oct 15, 2020 ]
Upgrading car audio in phases. Should I install my new speakers before installing Dynamat?
[ Will  Aug 25, 2020 ]
3 answers
God bless you, you should install the Dynamat first and then the speakers, so I did.Enter an answer to this question.
[ agustin  Aug 25, 2020 ]
Man, to be honest. It would be best to do them at the same time, but I understand working on a budget. You could install before or after installing speakers. It really shouldn't interfere with each other.
[ Christopher  Aug 25, 2020 ]
I would install the Dynamat first since you may need to remove the speakers before you install the Dynamat.
[ KENNETH  Aug 25, 2020 ]
Does this product heat resistant? Its gets extremely hot in Vegas.
[ Javon  Jul 21, 2020 ]
1 answer
Javon i live in Michigan so heat is not really a factor for me except for maybe a couple weeks out of the year. This is a very good product though and i would recommend it for sound suppression. My sub used to rattle the bracket for the rear slider window. Since installing this product the base is solid and no rattles can be heard thru the back wall of my truck. Hope this helps.
[ Michael  Jul 22, 2020 ]
I have a 2018 Nissan versa note hatchback, will one kit cover inside and outside 2 doors?
[ Jian  Jul 11, 2020 ]
1 answer
There is more than enough material to fit two doors. I put one kit on my 1995 Ford f250 doors (probably bigger than a Nissan), plus the floor wells up front. Dynamat is top of the line.
[ DAVID  Jul 21, 2020 ]
How much should I expect to pay my installer -labor only-for complete top to bottom up grade, ie sound deadening -Dynamat doors, canopy, floor, how long should it take, Ford 150XLT?
[ Stephen  Jan 07, 2020 ]
2 answers
My 2013 Hyundai Veloster took 5 days. The variable would be the amount of money you pay the installer and how time efficient he is. You can do it yourself, it is not rocket science; although you would need to find the time in your schedule and and transportation for your vehicle down time. P.S. I personally prep ALL my surfaces with a fine grit sand paper. That is an option. Be sure to clean your surfaces with ALCOHOL thoroughly before application. Second Skin offers a great selection of sound deadening. If your in that deep, You might as well do it right the first time...It is a royal pain in the ass to go back and perform a task you could done when the truck was already gutted! Trust me , a lesson learned the HARD WAY! Hit me up in you require any more advice.
[ john  Jan 23, 2020 ]
That is highly dependent on the installers, speed, efficacy, and hourly rates. There is no way for us to accurately estimate that.

What does open box mean and what measures are taken to ensure the product arrives as advertised?
[ AJGonz93  Mar 11, 2019 ]
1 answer
Our open box inventory has been opened and resealed. It is tested and verified fully functional and in pristine condition. It carries the same warranty and 60 day return period as brand new stock and receives the same shipping and handling as brand new stock.

Hi, I have a 2013 Toyota Tacoma double cab truck, I am interested in deadening the doors, will 2 kits be enough?
[ Guillermo  Nov 23, 2018 ]

I bought 2 kits for my 08 4runner and it was more than enough sounds awesome also replaced all 4door spkrs
[ LEWIS  Oct 15, 2020 ]
Yes it's important to do the inside of the door behind the speaker as well
[ onna  Nov 23, 2018 ]
? sorry for asking but how does dynamat work never used it before.
[ Roy  May 30, 2016 ]

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 ]

[ tim  Apr 06, 2016 ]

Thanks for your question. The manufacturer lists it as 0.085" thick. Hope that helps.
