I have never seen an increase in spl due to Dynamat. It may seem that it is louder do to reduced other annoying noises. I doubt 12 feet would be enough to do a regular trunk if you plan to cover everything. If your goal is spl I wouldn't bother, it has its place in SQ cars. But even then I would use a commercial product like used on machinery and semi trucks it is a lot cheaper.

I used around 40 ft of a mixture of dynamat and super dynamat in my car, and while I couldn't tell you if it was louder or not (mostly because there is no way possible for me to care less about how loud a stereo system is) I can tell you that it did make the car quieter allowing me to enjoy the details of the music more. I also never had a problem with the smell of asphault that many people have mentioned. I live in Alabama where it gets hot, damn hot, and it never was a problem. The stuff worked great.

Dynamat doesn't smell like asphault. The stuff people sometimes say smells like it is Snow and Ice Sheild. It is an asphault based roofing compound with an adhisive back that some use as a alternative to dynamat because of price. In the colder weather it could be used without the problem. However if you lived in Texas or Florida. You would probably get the smell....

I've used tar paper (roofing stuff) on the floor of a couple of cars. Just lay it, and then heat it up and roll it like you would dynamat, it's cheap, works well, and since it doesn't actually adhere, you could remove it if you wanted.

For an installer of 11 years, I would think that you would already be familiar with dynamat and its purposes. It is not to increase your SPL. What kind of car, or uh, SUV did you say you drive? Also, if you are unsure of measurements, you might want to try a tape measure.

When i was applying Dynamat Super to my door like i didnt have a heat gun. So i whipped the good 'ole propane torch and used that to heat the metal and the Dynamat so it was alot more flexible and formable. I did notice a smell.... like, roofing tar kinda with something else. Anyway.... If you get it hot enough yea it stinks.

Probably cause you are only suppose to heat it to a warm temperature, no *****it is going to smell if you burn it, RETARDS!
AND BY THE WAY... you cheap people that use roofing paper and stuff... lets getting somethin straight..... ROOFING PAPER is to DYNAMAT as PHOENIX GOLD, PPI, SOUNDSTREAM and others are to RF, THEY JUST DON'T COMPARE.....
So use the real thing or nothing!

Agreed DQ... 11years as a Pro hahaha with a question like that ..I recall his first post saying he was 15...now he installs as a pro for 11 years..
Hmm at age 4 huh....god i wish i was that smart at 4 years old
One prob BB is some people here have photographic memorys
I don't see anything wrong with using Snow and Ice Sheild. If all you are trying to do is stop rattles it would work fine. All you need to do is add enough mass to change the resonate freq. As far as sound quality goes I doubt there would be a whole lot of difference, but it would be their. After all they are designed to do different things. Also I suggested using a high quailty alternative from the commercial industry. Like Sorb-Tech it is far less money than dynamat, has a higher absorbtion value. Only draw back it only comes in big rolls.

Hmmm... Being a retired pro installer, I found sometimes the cheapest things you can think of work the best.... Guess saving money makes me a retard. Maybe I'd rather spend my money making my system sound perfect, and not waste it on a name brand that performs as well as a cheaper alternative. Maybe Hylton10 is the retard? But I digress...

my understanding is that the stuff decreases resonance and quiets the car so you can hear more detail.
Is critical listening down while driving 60 miles/hr or at a standstill? How does dynamat improve a parked car? Also if you have your componet set/coaxial in a kick panel, why would one need to mat the doors? or a trunk if your sub's in it's own box?

Dynamat will not actually increase objective SPL, but was designed to keep the noise levels INSIDE the cars down by up to 3 db or so, so you don't have to play the radio AS LOUD for it to appear as loud. It helps keep motor, tire and wind noise down, as well as other ambient noise.

The mat helps at any speed, volume, whatever. It only lowers the noise floor of your car. In other words, you by a metro, dynamat the hell out of it, and it drives as quiet as a cadillac. Thats all dynamat is supposed to do, kill noise. Any noise. Everything is damped by the stuff, even what you want is damped. I have seen about 3Db less road noise when it's used right. You do it on the doors even with the kicks to knock down road noise.

Also dynamat , etc stops the rattles !!! To give an example , even though I have my components in the kicks , and 8 inch subs in the centre of the dash , there is still 3 layers of mat covering the doors and all around the bars , etc inside the door . To have a really good sound spoilt by door handle linkages rattling against the inner door skin would be criminal ( maybe too strong a word !!! ) . The same applied to the rest of the car . I seem to remember someone ( maybe Earl Z ) even dynamatted every piece of plastic trim in the whole car for a similar effect . Even though panel ratttling may seem impressive to the crowds , it doesn't sound that good from inside the car
