Tin-can to almost Mercedes feeling, no joke!
By Carl Kriesant
I've had the dynamat installed in my '04 Subaru Impreza Outback Sport for about a month now and it was well worth the effort. When I say effort, I tore out my entire interior to install this stuff. Inner and outer door skins, entire floor (doubled up in places), trunk (doubled up again), rear hatch, and under my hood. It took a total of about 17 hours to install and trashed my hands, cuts and sore for several days. I used the dynamat heavy-duty roller for most of the installation and the handle of the roller to push the material into tight crevacises. My entire car, exluding the roof, took 2 3/4 bulk packs. I still have some left over and trying to figure out what to do with it...

The results: You could say I was skeptical like other users, mostly because I hadn't known anyone who used it or what dynamat was even made of really. It's basically sheets of tar (butyl rubber) backed with thick aluminum foil. This stuff is heavy, but pretty thin and tucks into tight places pretty easily. While at first I noticed an increase in my cars weight, it seems to be less noticable the more I drive. What's more noticable is the quiet ride and solid-feeling the car now has. The doors really do close with a thud and not that reverberating tin-can sound like before. The entire chassis feels much more rigid and stiff, like a higher priced, luxury car. My roommate, who drives a Benz C-class, said the stiffness was immediately apparent and the road noises was significantly reduced. This girl loves to drive and she was pretty impressed with the results.

The amount of road noise from freeways was almost difficult to carry on conversations or listen to music clearly before. Much more quiet now. If you've ridden in a subaru impreza, you know how loud they are! While it's not Lexus quiet, it's much, MUCH better than a stock subaru. There's still some noise, but I wasn't able to cover the firewall as much as I would have liked and my tires are lousy. When new tires are needed, I'm going back to a quality set and that should help a lot more. (BTW, Bridgestone-made Fuzion HR's suck a$$, but they are cheap.) I'm going with Bridgestone Turanza's next time.

My intention was purely to block out road noise and make a more comfortable environment for myself and passangers. A bonus to killing the road noise was the improvement in my cars audio quality. I had previously installed an Alpine h.u., Alpine speakers and Audiobahn d-class amp w/ a 10" sub and it really brought my system to life. I never knew what mid-bass was till after the dynamat was installed. I'm amazed to get that much thump, out of 6 1/2" door speakers!! I had to go back into the headunit and re-adjust my equalizer because the entire soundstage totally changed. It really allows me to enjoy my music to it's fullest without an amp for the door speakers, which is nice! My music consists mostly of hardcore, metal-core, metal and punk. The dynamat really brought out crisp, clean sound that wasn't distorted at higher volumes like before. It's also allowed me to tune in really precise and crisp bass hits from my single 10", enough to make my rearview mirror droop with each hit. I love hearing and feeling the kick drums in heavy music.

All-in-all, I am extremely pleased with the results. At first I was tired and my hands and back ached from two straight days of installation, all the while thinking "what the hell am I doing!?". But now, I can sit back on a drive, carry on conversations without raising our voices, listen to my music with better definition and clearity, or enjoy a nice peaceful interior alone. It's been well worth the effort.

Would I do it all over again??

In a heartbeat on this car. Hopefully the next car will be more quiet from the factory... if not, I'll probably dyanmat that one too!

Luxury and comfort in a box
By doc
I have to admit that I was a bit skeptical at first, but I am now a believer.

To begin with, if you look at the trend of reviews on Dynamat, it tends to show that people are either completely satisfied (5 stars) or unsatisfied (1 star). I suspect that those who are giving one star ratings either don't know how to properly install the product or they just expect miracles.

I have a '07 Camry which I love but roadnoise has been getting to my sensitive hearing lately. *NOTE: I have a leather interior which lends to a louder interior when compared to an upholstered interior. My biggest problem was music listening when driving on long hauls over roads that are rough. I would have to crank up the radio to hear it, and it was not even intelligible at that. With this bulk kit, I was able to line nearly my entire trunk, the rear speaker decklid, and the floorboard beneath the rear seat where the gastank sits. The results are phenomenal!

I am not prepared to tear out my entire interior to do the ceiling and floorboards and firewall, but beware it is a lot of work. With having prior knowledge of how to tear down my car, it took me 8 hours to completion for the rear of my car. Seriously consider taking your time to install it, and do it the right way.

If you do a rush job, you will have a rushed-job results and you won't be happy. You have to prep the surface which is just fine with a can of Denatured Alcohol and a white rag. It is imperative that you roll this substance on real good. The performance of this product depends on how you tack it to the surface. The more contact it has with the surface (ribs and creases and all) the better it will perform. I highly recommend the rubber hand tool as it conforms easier to bends in the metal making it easier to form. I suspect the wooden tool would do just fine, but it may be harder since it doesn't have any "give" to it for forming those tough spots.

I am very happy with my results. Without doing the whole car, I have cut my road noise in half literally. I notice no roadnoise from the rear now, it's all from the doors and front, etc. but I am not prepared to tear out my interior. The stock speakers in the car perform 200% better, although they still suck. Before the application I wasnt able to turn up the volume without losing the bass completely. Now I have decent full-range sound and I no longer have to turn up the radio to hear it. I used to turn up the volume to 26-30 just to hear it (which I still couldn't understand because of the noise). Now, I leave it at around 15 and never have to turn it up to hear it or even understand the music! No joke.

One last note on installation: if you aren't worried about the look of the install (because it is going to be covered with carpet, etc.) don't be afraid to cut it up. You will more than likely use every piece. It is much easier to work with in strips. Large curves are a son-of-a-gun. The product is very thin, but very tough. AVOID AIR POCKETS!

My doors go "kfump" now, instead of "klang"
By Dane Shepherd
I agree with the others; anyone who doesn't like this product must have installed it wrong.

I have a 2000 Honda CR-V SE. I lined the underside of the hood, the entire roof, all four doors (inside the doors and the surface), much of the floor, the spare tire well, the rear quarters (inside, behind the rear speakers) and lots of the tailgate with two (2x) Bulk Packs (9 sheets each.) I had not planned to line the roof, but after gutting the seats, all trim panels, and all the carpeting it seemed worthwhile. I cannot explain how differently the vehicle sounds now. EVERYONE compliments it (including my wife, who could not understand why I was spending the time and money on the project in the first place, but now wants me to Dynamat her Solara!) The doors go "kfump". Knocking on the hood, roof, or doors sounds like hitting a solid wood desk. There are NO vibrations or rattles in the car whatsoever (I also got some cheap self-adhesive felt sheets from a hobby store and lined the ashtray, glove box, and little change compartments. Now it's like driving around with ear muffs on. There is still some road noise, because I have pretty knobby tires, but the incredible thing is that I can no longer hear my exhaust from the rear of the car, and sometimes I'll look sideways and notice an 18 wheeler beside me that I did not even hear. When I pass vehicles going the opposite direction I am used to the "whee-owwww" as they go by, but now it is a "whiff", or just silent.

Lining the roof made a huge difference when driving in the rain, but since the windshield is so noisy in a downpour the cabin is still pretty loud, but there is no "ratta-tat-tat" from the metal anymore at all.

I bought a heat gun and the rubber Dynamat roller specifically for this project (though I'm sure I'll get plenty more use out of the heat gun). I agree with many of the other reviewers that if you do not press this stuff down in FIRM contact with your vehicle that you will not get the best results. I've done MUCH (much, much, much, much...) research on this and the bottom line is that this product is so effective because of "vibration damping", NOT sound blocking. If you hold a sheet up in midair between you and a speaker it will have no effect. If you glue it to the speaker you will virtually stop the sound.

I can also go on about how AMAZINGLY different that my stereo sounds, but I think everyone else covered that. Yes; more mid-bass. Yes; you will hear things in your music that you never heard before. Something that surprised me though was how much quieter your music is OUTSIDE your car. I am not a loud person, and I always turn the volume down at stop lights, and in residential neighborhoods, but one time I stepped out of my car and left the stereo on at a pretty comfortable level. When I closed the door I could not hear it at all. Nothing. Nada. That was a nice bonus.

This stuff is incredible when installed right. Amazon had the best prices in all my searches. You will ache, you will probably bleed, but a weekend or two of hard work should reward you for years. Enjoy!
