Xtreme Door Sound Dampening Kit with Four 12" x 36" Pieces
Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper.

This material works best for temperature ranges between 14° – 140° but can withstand ranges between -65° - +300°.Xtreme Applications
The Xtreme Door Kit is great for improving the overall sound quality in your vehicle by cutting out unwanted road noise. It is typically used on vehicles to reduce vibrations and rattles on the doors of your car. This kit comes in four 12" x 36" sheets combining for a total of 12 square feet which should be plenty cover the doors in your vehicle.Easy to Install
Use scissors, a knife or a die to cut the Xtreme to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Now it’s time to peel off the release liner and start applying. The easiest way to apply is to bend the mat slightly and attach it along its shortest edge. Using a roller, press the mat tightly into place, the roller will help eliminate unwanted air pockets. There is no need for heating the material, for best results the application surface should not be below room temperature.

Dynamat Xtreme makes a huge difference in reducing road noise and in keeping the sound within the confines of the vehicle. Don't cheap out either. Buy enough to line the 'inside' pockets of your doors. Before doing so I got a tinny, tip tip tip sound while tapping the outside door whereas after I got a nice heavy THUD! Also, remember to install it on a cool day or at night so if you misplace the sheet you can easily peel it off and re-do. By the next day this stuff holds with a death grip. See it installed on my build here.

I used this kit to cover both doors in my S-10 Blazer (its a 2 door) and it went in just fine. This would be a weekend type project, something to just take your time with and work out any air bubbles. It gives my truck that solid door feel. No more rattles.

If your going to put high end speakers in your doors, you need to have sound deadening for optimal sound. I'd recommend any dynamat product as the different kits just provide different options for where you want to apply it. Great product and its at a good price.

Wear gloves when installing! This product is only worth the money paid for it at Sonic Electronix. I cannot say the difference in the sound quality is even noticeable. I installed Dynamat thoroughly in the front door inner steel panels on my wife's Focus. The back I did not. All 4 speakers installed are identical Alpines. One in each of the 4 doors.
I cannot tell the difference in sound quality. Alpine head unit driving all 4 speakers and no others.
The car as a whole seems a bit quieter and more "solid" with the Dynamat, but I seriously doubt the efficacy of the product for audio reproduction purposes.
If extraneous rattling/vibrating noises are your problem, duct tape and/or chimney roof flashing will be just as effective and cheaper.

Dynamatt is still king in my opinion. In my last install I put it up against the hype of Peel n Seal from hardware store being just as good. Its not. Dynamatt much thicker so more effective and zero odor. Peel n seal will not smell as long as its used in a way that all adhesive bitumen is making full contact. If its used to cover door openings as in sealing, it will smell. Dynamatt is expensive but buying from this site is about 40percent cheaper than Worst Buy. I feel its worth the expense.

Great product! Installed in my 2008 Altima Sedan. It reduced road noise and speakers in doors do not rattle for me to appreciate the details of my music. Only concern is there seems not to be enough product in the kit according to my installer for full coverage. The same for the trunk kit. Definitely a must to complete a good sounding stereo system. Expensive as hell in retail store but Sonic offers it at a good price that I can afford.

I have this kit installed on my 2005 Dodge ram under my box with two 10" subs. It shields any rattling around the box which I built into the cab under the rear seats.
You can use the strips anywhere - very flexible.

I noticed a huge difference in the amount of bass out of my speakers after lining the doors with this. I'm only running off of two 6x8's in the back and it sounds like i have a sub. I highly recommend that you get this to complete any speaker install

Although this is for the doors, I used it on my truck lid and I have to tell you, It completely stopped my rattle. I have 2 15" kickers pushing 750 watts each and this stuff eliminated all rattle, just pure bass now. You will not be disappointed.

Dynomat is one of the best sound dampening mats on the market, but just a little bit to pricey. I bout this for my dodge ram doors and it cover 2 doors with no problems. Very thick and sticks extremely well.

I am running 2 sundown audio 12s in a ported box tuned at 29hz running off a Hifonics brutus 2400 amp and I have flex. And lots of it. But I have 0 squeeks or rattles and the Dynamat has cut down some of the flex, I'd hate to see the flex without the Dynamat. Haha. But I had enough to cover the front two doors completely in a 98 gmc Sierra (big doors) and I covered about 80% of the back wall of the cab under the back window and I still have one whole sheet left. This stuff is great and a good price for what It is. However, the metal aluminum looking stuff is very sharp on the edges so look out for that. You can install it without the roller, but I'm sure the roller helps out a ton.

I bought the Dynamat "door kit" to dampen the sound in the hatch area of my Toyota. The car had very little to no sound insulation materials in this area. I was able to insulate the wheel well areas on both sides of the car, and most of the hatch panels. The result is minor dampening of road noise but a high reduction of noises such as the brakes, road debris hitting the wheel wells, and high pitch exhaust noise. I would think applying a lot more Dynamat would further decrease noise, but the trade off is increased weight to the car.

Used dynamat on my entire car, first time doing anything like this, very easy to work with, cuts easily, very sticky yet able to pull off and redo if necessary. Use the roller, and wear gloves as the foil can leave nasty paper like cuts.

I've used this product before and my only wish is that is was less expensive. It really quiets down the vehicle and makes the stereo sound much better. It is easy to install and fit in all of the curves and sticks without any problems.

I recently put 2 12s in a nissan extended cab truck and in order to fit the box where the back seats WERE. Yes I stripped out the seats. all plastic, all the trim pieces, sealed 2 vent holes and saw zawed the sheet metal off that holds my jack to the back wall and covered every inch with this stuff and then stuck velcro in the center and all corners to hold carpet that is cut perfect. No road noise from back tires and no more vibratin from that thin sheet metal on the back wall. I want to go all out and do as much of the inside of it i can.

Dynamat is the best sound dampening equipment that I have ever used. I Have 2 door kits done which covers all of my doors. And I also have a trunk kit done in my car. And i can't hear any rattling at all, in or outside of my car.

Really works. Completely stopped all and potential rattles. I didn't have any being my ride is fairly new. Be careful wirh installation because the foil will give you a mean papercut if not handled properly.

Did the noise proofing post upgrading my stock speakers with Polk component for the front and rear doors - I do not want to stop my music
The quality of the sound is more crisper and no more vibrations on the door trim. I would definite recommend this product.

Restored my wife's Saturn sport coupe to like new. These Saturn's are nice cars but a bit noisy. So, when I upgraded the stereo speakers, I Dynamatted the doors, rear deck and trunk. Big improvement in reducing car and road vibrations and noise.
This insulation really lets the new sound system shine now.
Thinking about Dynamatting the floor, firewall, and maybe under the hood.

Over the years I have used several sound damping materials in my cars. Dynamat has consistently proven to dampen the sound as it it marketed. If in doubt, get some. If you are new to sound deadening and can not afford to purchase all the material for your car, I would recommend placing the Dynamat on the lower portion of you car doors first and work it as close to complete coverage as possible and then work your way up the door. Follow that with coverage on the floor and then the roof area. Dynamat also works on the back of rattling plastic panels. I continue to purchase more Dynamat as my projects need it. Dynamat is worth your money, and should be the first step in your sound system. Lowering your sound floor will make your ride sound/mentally feel better in that alone to your passengers. Less noise to overcome means less power to achieve the sound that you are looking for. Go forgot and buy as much as you can. It'll be one of best investments that you can do for your car!
