Check out this site.



If you look around, you'll probably find the answers you want.

I've already plastered the doors and entire trunks of my cars with the V1. I'm thinking about putting Teklite over it.

To do all 4 doors and your trunk you can use as little as 30 sq ft, or as much as 100, it all depends on whether you are doing problem areas, or every sq inch.

If your trunk lid is rattling, dynamat will not help. It is not the actual panel that is vibrating against itself, it is the lid rattling against the car. I have had this problem in many 7th gen accords that I have done installs in. The best fix I have found is to back the rubber stoppers out of the trunk lid (the 2 round 'bumpers' in the corners of the lid) a little by unscrewing them a bit. This will put a little more pressure against the lid when it closes.

This is not a solution to vibration noise, and should not be a substitute for dynamat. I have dynamatted entire cars, and the result is amazing. If you do the whole interior (floor boards, doors, etc.) you will be pleased with the result. It makes for a much quieter, pleasant cabin. You will be able to enjoy your music more, since you are lowering your sound floor. You can do your roof, but it is much more tedious than the rest of the interior. I would recommend buying dynamat extreme in bulk packs on ebay, as it is cheaper per sq. ft.

When you get to doing it, I would recommend a dynamat roller, (the rubber one, not the economy wooden one) a utility knife, and a pair of mechanics gloves. Use the roller to make sure the dynamat is adhered properly. Use the knife to trim away from holes that door fastener clips lock into, bolt holes, etc. and the gloves will prevent slices to your hands (very easy to get if you are using dynamat extreme, since it has a foil layer, which can have sharp edges) Remember that the rubber part will stretch, but the foil layer will not, so when you are doing lots of wavy areas or large curved pieces, cut the dynamat into smaller pieces and lay them on more like a puzzle rather than trying to use one large sheet (i.e. transmission tunnels and spare tire wells)

I hope this helps you out!

Look Up RAAMaudio and that will tell you how much and just email the owner and he will tell how much you will need. I have bought my stuff from him and he is a really great person. I bought enough to do my car for about 350 not really that bad.

I have quite a bit of my interior done with dynamat.. the rear deck and quarter pannels, underneath the backseat, and the doors.. it made an unbelieveable difference in the bass response of the stock speakers.. There is MUCH less road noise and zero rattles.. Its an amazing difference..

I have not, however, done any of my trunk because i dont have a sound system..

How much did that cost you? How many layers? If it's too much I'll do it myself.

do it yourself! I was intimidated by my mercedes at first... it made me learn the interior and is an easy over the weekend project... I removed all my seats and did the full nine yards with the complete trunk, hat rack and all door panels... 1 layer of damplifier everywhere, 3 layers of fatmat throughout the trunk with some key places reinforced with a base dynamat xtreme i required a 50 ft roll of ... i think total i used 225-250 sq ft.... for a small sedan ..lol, i was thorough.

but yeah, DIY if u have the space and time... you might go buy some clips for panels...for MB they were pretty much all 2 different types of clips but i probably broke 2 total. I shouldve taken pics of the process..it was hilarious seeing my car so stripped down in 8 hrs and with pages printed out from my forums detailing proper removal... i was installed my 2 10" P3's and wiring was made a whole lot easier combining the sound deadening w/ wire channeling for speakers & subs

How did you get the door panels off the Mercedes? My mother has a 95' E320 and one of the speakers is blown. I have no idea how to take off the door panel. My other alternative would be to hire somebody to do it, but I've already had a "professional" replace the speakers, headunit and add an amp. The guy mounted the amp upside down, and as I drove the car more and more, I noticed lots of loose panels because of either loosened or broken clips.

It cost me about 120 dollars for 32 sq. ft. of the dynamat extreme from ebay. I only did one layer. You should DEFINITELY DIY.. Its not hard to do you would just need an entire saturday to finish the job..

What i did was take out all the pannels after work on friday and then i installed the dynamat and put the pannels back in on saturday..

As far as advice for intalling this material you need a rubber roller, gloves and a razor knife, thats basically it.

After seeing the pictures of the similar material on edesignaudio.com, i would purchase the material from them.. Its MUCH cheaper and looks to be exactly the same as dynamat extreme. I dont think there could be much of a difference in performance. I plan to buy this and do the entire floorboard.

I never bought from anywhere else except at Elemental Designs (ie. edesignaudio). I bought 100 sq. ft. of the original V1 and it worked really well. In hindsight, I probably should have gotten the liquid (easier to cover nooks, crevices, etc.) or at least gotten the thicker V2. I must have put a ton of the V1 in my Prelude and the TL-S. I didn't notice much of a difference in the TL-S, but the Prelude is definitely a lot quieter. Although I can still hear the aftermarket muffler pretty well when I step on it, the car's actually pretty quiet when I'm cruising on the highway.
I just got 50 sq. ft. of their V4 Teklite (not cheap!) and add them to the doors and trunk of the Prelude and the 07' EX-L. If I'm lucky, I'll have enough for at least all the doors. If I'm real lucky, the Accord will be as quiet as my IS!

If you're considering the Dynamat Extreme, check out the stuff at Elemental Designs. (). IMHO, I think they have better stuff at better prices.

At edesignaudio.com, is the v1^2 really $1.00 a sq ft and the V4 only $2.00? It seems so cheap I just want to be sure that i am reading it correctly

That is what I got out of it. I like the UE line that is the type of sound deadening I got for my car but at RaamAudio it is 1.90 per sqft. The Butyl is a ligher matt and it works really good. I bought 2 rolls and 7 yards of the ensolite to give the doors a finished look for about 350. Also as for dealing with this company the owner is really nice and will answer any all of your question. When I first placed my order I order too much ensolite. He emailed me to make sure and informed me that i was ordering way to much and then took my car and system information and told me how much of everything I would need. Very nice guy.
