- Dynamat Xtreme Sound Deadening Car Insulation Door Kit 10435 – Pre Cut Noise Dampening Kit for 2 Standard Car Doors – Easy Self Adhesive Install – Made in USA – 4 Sheets 12”x36” Each, 12 sq ft total

I bought this to improve the cab sound in my Dakota Quad Cab when I was installing new speakers (my wife blew out the old ones!!). It was very easy to work with and install. All I needed was a utility knife to cut the mat to the sizes I needed for the install. It will stay on after it is in place but it is forgiving on install. This means you can make adjustments with the piece you are working with before you roller it down. Using the roller tool (sold separately)was worth the price of admission. It definitely made install easier and was able to clear any air pockets as well as give excellent adhesion. RESULTS: After the install there was a quick difference that could be heard. First thing you noticed is that when the doors are closed they sound more like a luxury car door closing. No more hollow sound, they sounded more solid. The sound in the cab is reduced and this is noticeable when no radio is on. Road noise has been reduced and it is a much nicer environment. As for the music...much nicer listening and clearer due to no competing noises from the road. Everyone who enters the vehicle likes it and knows there is a difference. NOTES: I installed this on the inner door and the outer door. Some sites and installers will tell you this is unnecessary but if you are in the door why not. The thin sheet metal is all that is between you and the road. This pack covered two doors in the front. I bought two boxes to cover all four doors. It took one afternoon to install and it was complete. This is not a hard project at all. If you can get the door panels on and off you can install this product. PRICE: I checked all over the internet and found that Amazon had the best price for this. From my experience this is likely to continue. Free shipping just solidified the deal. Check what you might need and compare the 4 sheet and 9 sheet boxes. Most of the time 2 4 sheet boxes will be cheaper per square inch and get the job done. Check prices and decide before you purchase. OVERALL: I am very pleased with this product and would recommend it to anyone. It does what it is advertised to and is very easy to install. It will not make much difference if your vehicle has a lot of soundproofing already but if your car does not then this will do wonders. My truck had some very small pieces of factory mat in the outer door metal already. They were just covered by the Dynamat. You may find the same thing during your install. They must think the truck needed some. I just took it up a notch.

Honestly speaking, this is one of the best products that I have ever purchased. I'm an audiophile who installed a high-end stereo system (4 Polk Audio MM6501, JL Audio XD400 amp, and JVC XR-810 receiver) into a new VW Tiguan. The primary reason that I installed dynamat into all four of my doors was that I heard some rattling at higher volumes. Not only did the dynamat eliminate the rattling, it truly improved the sound by a large margin. Bass and mids became "punchier" and more lively. Unusually, volume increased by about 20% when measured against the volume knob on my receiver. In sum, it transformed a good sound system into a very good system. I'm still ironing out the sound between my amp and receiver to turn it into an excellent system, but the dynamat more than did its job. BTW, I used their better roller, which worked excellently. I had NO problems getting cut despite not using gloves and using only moderate awareness and care. Since my doors did not allow me to lay it out in large strips, I had to cut it into many shapes using heavy duty scissors, which worked very well. Once you remove the paper backing, the material adheres to the doors easily, but not so readily so that you can't lift if off again to place it where you want. The patchwork that I created may not have been pretty, but it worked very, very well. The extra weight on the door makes a nice solid sound when you close it as well. Honestly, I can't imagine any cons to this product. Very easy to cut, not too sticky, easy to roll out the air -- and it improves your sound my a large margin!

I was looking around for alternatives, but was scared off by some reports of lingering odors. With the price here on Amazon (almost half of MRSP) I went for it! Glad I did - I enjoyed the luxuries the brand name afforded me (sticks well, but will permit pulling back off for mistakes). I skipped getting the roller and never looked back - use a tennis ball! It works just as well. Actually, better - because it gets in the odd nooks and grooves that a flat roller can't. I bought two of these kits for my 2013 Forester. I was able to cover the insides of my doors completely, with a respectable amount of scraps left over to spread around on each door's outer panel too. (I'd say I was able to get about 1/4 - 1/3 coverage on the outer panels.) I kinda wish I had ordered one more kit to get complete coverage on the outer panels while I was in there, esp. at these prices, but my doors have a nice, solid thunk now so I suppose I don't have any regrets. The results on my 2013 Forester: WAY better than stock!! I was kinda bummed when I bought my car at the hollow, cheap sound of the doors. They're much, much better now - more like a luxury car. It didn't do quite as much for road noise as I was hoping, but that sound comes up from the floor and wheelwells so I suppose I was hoping for a miracle by just doing the doors. For cost+effort vs. benefit, I'd wholeheartedly recommend dynamating the doors like I did. Vast improvement. I found it easiest to peel back the corners, tack the dynamat up and draw my cut lines with a sharpie with it hanging there. Then I'd take it down and cut. That way I had my leftovers before I applied it, and was able to reach inside the door the apply them to the outer panels before covering the inside. Since it's still winter temps outside, I did this install in my garage with a space heater. At first, I was warming up the dynamat in front of the space heater before sticking it on, but it's easy to heat it up TOO much... even to where you can't get the backing off! careful. Final tip: dynamat over your speaker hole, then go back and "pie cut" the opening, and wrap the slices back. Makes for a very solid speaker mount.
