I have a 97 Gt, i currently have one Jl 15 W3 powered by a rockford 1400 watt amp. And eclipse speakers running off my poineer head unit. I have always wanted to Dynamat my car. But i have been skeptical. First, what is the best place to start using dynamat, where you get the biggest difference, i would think its the doors, but im not sure. Also, i am not very good at audio install, how hard is the dynamat install???
Thanks

hardest part about install is removing the parts where you want to put the dynamat.. its basically like putting a really sticky sticker on.. i just have that on around my speakers not covering the whole door or the entire rear deck...
really made a huge sound difference... alot less rattle
dynamat's a good enough product but far to expensive I.M.O. The purpose of sound deadening is to add mass to the offending panel's. So with that said, anything that will stick and add weight will do almost the same thing. I've had very good luck with Peel an Seal roofing membrane ( availeable at your local home improvement megastore). Also I've heard pf people using roll on/spray on bed liner.
I've matted many a car, and the doors are the best place to start.... but it all depends on what your looking for. If trunk rattles are a plague to you, start there. Like he said, find the offending panels on deaden them. If you want better sound quality at a lower volume, do the doors along with the trunk, though I would recommend doing the entire inner skin of the door, that way the speakers aren't fighting the noise from your tires, engine, other cars etc. You'll here more music without having to crank the headunit to the point of introducing distortion (speaker killer). For the ultimate sound deadening, strip the interior of the car down to sheet metal from the firewall to the taillights and cover every piece of steel you see from the entire floor to the entire roof. This wiil be like being in a coffin six feet under. You won't hear a thing from the outside world.... even at 120MPH. Just pure musical bliss.... You will here parts of the music you've never heard before. I would only recommend this to someone who is really into competition such as IASCA or USACI, even dbDrag. It is very expensive, and will add alot of weight to the car. But if you just want kill some rattles, just find em and deaden em. A little tip... let it lay in the sun for a little while to make it more pliable, it will form to bends in the metal much easier this way. Also, get a small roller to press it on easier. Oh yeah, keep some razor blades handy. You WILL be doing some cuttin... Go ahead and do the doors too, trust me, you won't be disappointed.

It's very easy to install; pre-glued and adheres as soon as you press it onto a flat metal area. The most time-consuming part is disassembly to find bare metal.
The doors are a big area of the Mustang where road noise comes through to driver and passenger, so I did them first; then the back decklid, trunk and back side panels. Some people tear up carpet and take out their seats to cover everything. Not me. Too lazy.
One caveat; don't cover up *all* the holes cut into the metal under the door panels in an attempt to block out every last bit of exterior noise, like I did at first. The door panels need to snap into some of them. Found this out the hard way when my door wouldn't reassemble. Keep the original sticky paper door liner as a guide.
Warming it up helps when trying to stick Dynamat over lumps. I ran a blow dryer out into the driveway and stood there blowing hot air on the doors, while rolling it down smooth with a wooden roller tool from Crutchfield. This was in 20-degree weather.... the neighbors thought I was touched in the head! The previous poster's sun-warming method is a lot less embarassing.
Yes, it does weigh down the car. By the time I put in two 10" subs, 80-lb enclosure, wiring, cap, amps, rack and Dynamat, it must've added over 150 lbs. Now I'm compensating for the weight with more performance mods. Future plans include Trimspa and a Procharger.
You won't hear a thing from the outside world.... even at 120MPH. Just pure musical bliss.... You will here parts of the music you've never heard before.
Funny, I've never taken you for a ride in my Ranger, yet you seem to know quite a bit about it.
My interior is completely covered with Dynomat. Even just listening outside of the open window does not do it justice as you MUST get inside to understand how the music really sounds.....and then I can hurt you.....with the volume knob....
when i bought my dyno-mat i was a litttle unsure. the work to install it is worth it! i have had some pretty heavy systems in my car and used to hate the rattle!!!!! Everything rattles.lol two thumbs up from me!

I know I have jumped in a bit late, but I'm currently in the process of doing this and noticed a huge difference after doing just one door. I still have one more to finish and then I can really test the system. I tell you what though, it was a pain in the butt to do the trunk, but it was worth it. A local shop was going to charge me $600 to do the doors and trunk. Screw that. That money could go to mods. Long story short, Dynamat is great. A little pricey (get it from ebay; its WAY cheaper there), but very effective.
Interesting, I am also in the process of putting dynomat in my vehicle, I am re-doing all of my interior and I read up on sound-deadoners and I thought it would be a good idea, cool to read some stuff on the topic on these forums.
I am planning on doing my entire car with it though, I really hope the stuff isnt truly as expensive as you all say
yo i got like 50 square feet for 70 bucks after shipping on ebay. Its Not the trademark Dynomat, but a sound deadener just the same and i have no problems with it.
i did my floors and rear interior on my car, and have a sh** load leftover. its a great investment though. And the best part about it, you can put it in ANY car.

Honestly, unless you are doing a competition, it is pointless to do the entire car. I mean, if that's your personal preference, then do it, but that is a lot of weight, not to mention timre and/or $$$$. If you do it yourself, you will experience lots of & , but it will save you $$$ which is always .
I just finished the doors and trunk and it is like night and day. The bass is so much tighter and the music stays in and the noise stays out. I can barely hear my SLP LM's with the volume @ 15. I HIGHLY reccomend this if you have any rattles.

I just did the trunk and under the rear seat in my 2003 GT Vert and it's like night and day.
MUCH less road noise and so forth.
To be honest, I didn't expect much but I was pleasantly surprised.
I didn't even do that great of a job in that I only did the spare tire well and out onto the sides of the trunk bottom .
I didn't do the top of the trunk....
I think doing under the rear seat made the most difference.
Not cheap, and I now there are alternatives that are less money, but I have to say it did make a major difference in cutting road noise.
How good is Dynamat??
