Great bang for your buck, easy install
Color: Without Logo Size: 50 sq ft
I do audio upgrades everytime I buy a new vehicle and on my newest truck I had just ordered new speakers and figured I'd try out a sound deadening mat as it's a 1997 vehicle and has no noise canceling materials at all, and any audio person will tell you sound deadening is the first thing you should do. So I ordered this and put it on the door panels while I was wiring in the new speakers. And the sound mat on just the door panels made a huge difference in bass quality and quantity. And also changed the sound of closing the doors on the vehicle from a metalic clang to a deep solid sounding close. I plan on putting a new carpet and headliner in the vehicle this summer and will definitely be using my leftover mat on both and ordering more if needed. ... show more

better than Dynomat?.......
Color: With Logo Size: 50 sq ft
For the price you really cant beat this product. I believe Dynomat is roughly twice as expensive and Its definitely not twice as good. From using both products I would say you would have to use 1.5x as much FatMat as Dynomat to achieve the same results. Its relatively easy to work with, I find cutting it into small strips works best. Be sure to roll in on to the surface with a roller, and don't forget to get in all the creases and crevices. It comes with a small box cutter knife and a crappy plastic roller, which I broke about five minutes into the project. Definitely recommend investing in a steel roller and regular box cutter(with blades, they are going to get ruined quick). also if you don't have a roller the back end of a screwdriver works just as good if not better sometimes for getting into those hard to reach places. ITS SUPER IMPORTANT you make sure it firmly stuck to the surface or it wont work. I found wiping the surface down with a clean rage and some degreaser or acetone is helpful. There is a lot of complaints about the smell or it not sticking good. I have no idea what these people are talking about, the smell went away in a day and its almost impossible to get this stuff off. I used it to soundeaden the trunk and rear deck on a 06 impala and still had a little left over. I put 4 RockforFosgate HX2 power 8" subs facing up in a ported box with the port coming out the rear deck into the cabin powered by a Rockford t1000.1 amp and there is almost no rattles. ... show more

Gets the job done
Color: With Logo Size: 50 sq ft
50 Sq feet was just enough to isolate the trunk, trunk lid and rear deck of an Acura TL. This stuff is quite heavy and I definitely felt my trunk lid get much heavier. The tools included got the job done without problems. The whole install process took me a full day just for the trunk. It is a tedious and time consuming process especially in hard to reach areas where you have to cut small pieces, and rolling out the bubbles also takes a while. Make sure to do this on a warm day so the material is flexible and easy to work with and make sure you thoroughly clean the surfaces with either alcohol or some kind of degreaser. It's very sticky, once it touches the metal it's hard to take off, and if you do take it off it wont stick as good anymore. So be prepared for a lot of frustrating moments. The adhesive used is not my personal favorite, it's a rubber and asphalt based adhesive, which smells,(sorta like fresh asphalt) but smell gets better after a while. I'm not sure how long it's going to stick though, I've seen people who used this and some pieces peeled off after a while, a little spray adhesive should fix that. I did hear a slight improvement in bass clarity and there's significantly less rattling. My friend with the exact same car and sound system setup did Dynomat on his trunk, there was a bit of difference, but not much at all and he paid double of what this cost. One thing I have to give Dynomat is that it doesn't stink up your trunk. I'll see how long this stuff hangs on for, and if the adhesive will get saggy and leak, then I'm probably getting more for the doors and floor. For the money, it's a good product. Unless you're building a 1000+ watt system, this stuff will work, if anything you can double layer it. ... show more

Love this stuff! Good Quality. Good Price.
Color: With Logo Size: 50 sq ft
Used this in a 95 Chevy C1500 Ext Cab. Covered the floors front to back, across the back of the cab, inside the rear quarters, and across the rear part of the roof. I had maybe 3 square inches of various scraps left over. The stuff is thick, dense, adheres well, and comes with a roller and cutting blade. The roller came off early in the process, so I took a cotter pin that fit the groove on the roller, spread it open around it, and then pinched it back closed, and continued on; still working after the job is done. I have an aftermarket exhaust on my truck with duals that have quite a rumble. I started the truck, with the doors closed, while the floor was bare and took note of the sound levels. After the install I repeated the process. There was a significant drop in the noise levels from the exhaust and no metal rattle from the stereo. Frankly, I'll probably pull the door panels and cover the insides of door shell and the rest of the roof before too long. The less road noise you have, the better your stereo will sound. :) ... show more
