Dynamat Xtreme 20' Trunk Kit

Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminum constrained-layer vibrational damper. The Xtreme Series adapts and conforms easily to sheet metal and other hard metals vehicles are made of. This material works best for temperature ranges between 14° 140° but can withstand ranges between -65° - 300°.

Xtreme Applications

The Xtreme Trunk 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 in the trunk. This kit comes in five 18" x 32" sheets combining for a total of 20 square feet which should be plenty for any size trunk your vehicle may have.

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 its 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.

Product Features
  • Dynamat Xtreme Trunk Kit
  • Five 18" x 32" sheets (20 Square Feet Total)
  • For the trunk floor, side panels, and trunk lid
  • Add SPL to your vehicle
  • Improves bass quality
  • Reduces bass distortion
  • Reduces trunk panel vibrations and road noise which helps to clarify the overall tone of your subwoofer
  • Easy self-adhesive application

June 9, 2010

It is well worth it. From a small system all the way up to the whole trunk filled with subs. I have 2 15"s and it works great. Of course its not going to take care of all the rattle with that much power but it sure does help. I would recommend getting the tools with it or use something similar that you may have laying around the house. It gets tricky if you dont when you get into corners and awkward spots. It was a little small for my trunk in a 2007 mustang so another pack would have been helpful but I most def recommend it.

I ordered the Dynamat Xtreme 20' trunk kit to outfit my 1995 Integra and it worked out perfect. I was able to cut my expenses in half by going through Sonic Electronix. I really frowned upon my local dealers after doing business with Sonic Electronix, who would have thought that you could get such a solid deal.

The ordering was simple and my shipment was speedy. Hands-down, very pleased with Sonic Electronix and I will be doing business with them again in the future.

Thanks!

I am exteriencing the greatest sound system I've ever had. The Dynamat Xtreme truck kit I purchased for my 2001 Mustang Gt stopped any and all rattles from the truck(1Kicker L7 12). The kit also blocked alot of noise from the outside including my Borla exaust note which is pretty loud. I also have a double layer(outer&inner) of the Dynamat Xtreme on the doors along with Dynasorbs behind the speckers(Infiniti Kappas). I would reccomend this product to anyone wanting a quiet cabin. Thanks Ron

November 20, 2011

I used this Dynamat in the trunk of my '97 Honda Prelude (small trunk) and I was able to cover the entire inside, including the trunk lid and still had one sheet left. The result has been incredible. The bass is warmer and louder, and there is absolutely no rattle. Not only that, you can barely hear the bass outside the car when the music is cranked. I'm running 1000 watts RMS to a single 12" ported box.

I have 2 pioneer premier 12's that I bought from Sonic. I looked at dynamat on other websites and their prices were outrageous. Sonic Electronix has the best deals around.

No rattling, No road noise

October 12, 2010

Does exactly what its supposed to do. F***** is a cheap ripoff that provides no sound dampining and falls off in cold weather. S****** R******* works just fine but material is folded which being stacked causes it to stick together and will take you 30 min to peel backing off.

1 sheet of Dynamat is rolled, not folded. Made installation a breeze but the wooden application roller is a must have!

Decent - But Missing Items

June 2, 2013

The dynamat does its job. However in places like Texas with high heat, it is prone to melting and leaking out the sides of the strips you cut. The package was missing the roller so I couldn't make it as flat as I needed.

I was able to cover most of my trunk, along with other areas like the top and bottom of my rear speaker deck. From what I have done so far, it has made a significant difference in the rattling of my car. The dynamat was easy to work with, a little messy, but not too bad. This was a great buy, and would recommend to anyone who is into serious bass and sound for competitions. Thanks Sonic Electronix!!!

If you buy good subs or sub you have to buy this product or else your subs wouldn't sound good outside the car and even inside your car. This product reduces rattles around 70-95 percent. Its worth any penny!

this stuff really works. It doesn't have to be used for the car as you can use it for home theater and to muffle the sound of your power supply inside your computer. As for the car, this stuff really eliminates the rattling and road noise.

The downside to this product is that it does add body weight to your car, so go easy when you apply it to the doors. As for the trunk area, I'd recommend 2 trunk kits for most trunk sizes.

I bought {2} of the Dynamat Trunk Kits to cover my entire trunk in my 2007 Buick Lucerne CXL. It took me 3 1/2 hours to install, a lot of elbow grease, a tall glass of ice cold sweet tea, the Dynamat Rubber Roller & a Band-Aid to get the job done. I put a pair of the 12" CVR's in a ported box and those suckers POUND!!!!!!!! No rattling, less road noise & the bass is louder. I highly reccomend this product to my friends & car stereo fanatics around the world!!

Review for Dynamat

December 6, 2009

Its Dynamat.... Black and gooey on one side foil on the other.

Pro: Less rattle and road noise.
Con: Tearing the entire interior out and adding almost 100 pounds. cutting hands on foil and car. Bleeding all over. Getting gooey residue stuck on jeans.

Handles your ratlles for sure

October 17, 2007

I just installed 10' of the 20' in an Acura MDX and it helps so much with the rattle from my new 10" sub. The stuff is kinda pricey but does the trick. You need 40' or more if you want to do the whole car (doors (4) and trunk). Removes all high pitch rattling and helps so much with deadening the major rattles like door panels being rattled by serious base.

Dynamat is a Must

November 8, 2010

Dynamat is a must if you want the best sound tone in your car. My setup is 2 12" cvx 12's and 1 SX 18 (Kicker) in a regular cab f150, i used Dynapad on the floor and Dynamat everywhere else I could put it. I have 4 mids and 8 tweets, with the alpine imprint processor, I have never heard a vehicle sound so good and I know it wouldnt be that good if the sound tuning material wasn't laid in there, Thanks Dynamat!!

November 28, 2011

I bought 3 of these kits to do my truck. I still need 2 more kits. Easy to apply but, make sure you clean the areas where your applying or it will not work as good. Found out Mr. Clean and then rubbing alcohol works best. This stuff will cut ya so have a first aid kit handy. My cab is pretty solid and has a thud sound now. The back cab and floor still needs deading. I still have the 1/2" dynaliner to apply on top. My gas mileage has almost doubled since adding dynamat. Make sure to check out www.dynamat.com to get an idea. I covered pretty much every hole with strips and then layed my whole sheets. You'll see when you see the SPL section on doors. Mine is just as good without the dynaplate. Dynamat support said it would be like having the dynaplates installed. Course I'm building a compitition system for Iasca. I still need total of about $700.00 more dynamat, dynaliner, and another door kit. My doors outer skin, roof, king cab area took me about 8 hrs with small breaks, cleaning, applying and putting back together.

My friend, Erin, with a Ford Taurus put this in his trunk to stop his MOJOs from destroying his car. It works! Bass stays in the car and he POUNDS his subs!

If you are going to get subs, you have to get Dynamat trunk and license plate kit. You have to get Dynamat everything if you want quality!

I am also going to buy this as soon as I get subs and my battery from sonic.

(By the way, good luck finding one for cheaper)
