Trunk application quieted down road noise alot, Aug 30, 2010 Used this on my honda fit and Dynamated the spare tire wheel well. removed the tire well covers and sheeted the tire well. A dramatic improvement in road noise. Estimate a 3dB redcution at 30 mph. I Plan on putting some more Dynamat on the spare tire well cover in the front wheels. That should yeild a more few db loss of road noise. Now long road trips will be far more pleasant.

Resonant Evil Aug 07, 2010 My 2004 Honda Civic had some rattles, but mainly suffered due to the thin metals in the trunk and door areas. Despite installing new speakers and a powered sub (an Infinity Basslink), my music really sounded muffled, with a metallic tinge and a lack of mids (especially in songs with vocals). Driving on the freeway always meant turning the volume up, which made the music louder but didn't help in terms of quality. I tried stuffing the area behind the rear wheel wells (on the sides of the trunk) with foam, but that didn't help much.
I bought two of these bulk packs back in January but didn't have the time to put them in until late July. I didn't use a heat gun, but did set the sheets outside in the sun for a bit before using them (which did help make the adhesive stickier). I used some odd things (scissors, a chisel to push down on hard to reach areas, the rounded handle of a screwdriver) as well as an old wooden roller, which is basically a necessity if you want the Dynamat to go on evenly and look smooth.
I planned to Dynamat the trunk, rear deck, all four doors and under the rear seat area. Taking out all of the lining, popping out the door panels, etc. took a while, but as I had done it before it wasn't difficult. I eventually also Dynamatted parts of the center console and even under the steering column and glove box. It's recommended to use denatured alcohol to wipe down the metals beforehand, but I just used rubbing alcohol and a microfiber cloth. Application is pretty straightforward, but unlike most people, I didn't totally cover the surface of every area, just the majority of it. In other words, the trunk is mostly covered but the rear deck and doors just have patches of Dynamat in certain areas. After scouring many forums, I learned that Dynamat is mainly for vibration dampening and a little goes a long way, so I cut a lot of strips and squares for the doors. Also, certain parts of the car had a secondary metal that was much thicker and didn't really need matting. Conversely, a lot of the plastic trim is thin, so I used Dynamat on their insides (including the insides of those door panels). I ended up using around a box and a half of Dynamat in the end, and plan on using the rest on the ceiling (and/or under the front seats) in the future.
I was skeptical in the beginning, but wow, it really did make a difference in terms of sound! You've probably read that your trunk, doors, etc will now sound heavier and denser, and that's true. The real treat is how much better my music sounds. I can actually hear the vocals loud and clear now, and the sub hits a lot harder. I actually had to fine tune my equalizer and reduce the gain on the sub a bit to even things out, but it's definitely an acoustic improvement. I was thinking about buying an amp or two but now I don't need to!
The only negative I found was that sometimes when peeling the paper backing off, it will tear and you'll have to dig into the adhesive to get at what's left behind.
Another thing to note is that the Dynamat adds weight to your car. I'm not sure how much it is, maybe 50-60lbs for two packs like this...which doesn't sound like a lot but is noticeable once you get back on the road.
No bad for a cheap purchase Jul 30, 2010 Where I went wrong was not buying the bulk to save money, be sure to have a wooden roller and a heat gun. I did my application on a really warm day and the mat was flexible and sticky but still need to be rolled into contour areas. I bought the bulk package to line the 4 doors of my 2001 Chevy Blazer since i was in the mood to fix it up. The product works as stated, easy to apply and reduced the door vibration as well. Road noise was reduced as well, I will be installing some under the floor mats to quiet down more road noise.

dynamat 10455 Jul 24, 2010 I put it in my two front doors (doubled on the outer and inner panel) and the rear hatch door. I still have a bunch left so I might do more but it takes so long I don't know if it's worth it. The first door took like 3 hours until I got the hang of how to do it and how to get the doors off. I can't say this isn't a good product, it obviously does make a difference in the sound but I don't know if it really works in my car. I probably won't know until I get new tires since I still have the stock, which have been said to be obnoxiously loud. I put this in my 2001 Toyota supra and I honestly can't tell if it made a real difference. Sure it seems like the road noise is duller. The wind sound isn't as harsh but did it actually improve anything? It sounds like it got rid of some of the higher pitched road noise but the low dull roar still gets through, which might just be because of the tires.

only the best Jul 03, 2010
when it comes to sound proofing don't try and save a dollar. dynamat should be your only choice. other products smell like roofing tar.
you can buy a cheaper product but you ain't gonna like the smell on a hot day. i have 4 bulk boxes of dynamat in my 40 pontiac. it smells great.
thanks dynamat
