- Wed Aug 15, 2007 4:16 am #19849 The new Dynamat extreme works VERY well. Some of the other cheaper imitations do a great job at first, but the adhesive gives out and it falls off of vertical surfaces (or under the deck-lid) after a few months.
You get what you pay for.


but one piece of advice. MAKE SURE you get the surface CLEAN and dry before applying. use de-greaser.

I have dynamat-ted with some great success.
But if you do the whole car, you just added 100+ pounds.
Depends on what you want.

I can post some links on how to install if you want.

- Wed Aug 15, 2007 4:31 am #19851 Yea, it is really dense stuff. It adds a lot of weight to your car.

doing your doors and trunk/decklid will GREATLY enhance the sound of your stereo, because it solidifies the surface that the speakers are mounted on, and the surface that soundwaves bounce off of.

But to cut down on road noise, the best application of it is your floor pans and wheel wells. If you pull the carpet and do the whole bottom of the car, including up over the wheel wells, it will make your EG sound like a Lexus. (well... slight exageration).

I have heard (never tried it) that pulling out your headliner and applying dynamat on the roof of your car makes a big difference on wind-noise.

But if you do all that, your car will feel like the nose-tackle from the Jets is permanently residing in your back seat.
:shock:
Good tires (as previously stated) can really help with road noise.

I will post those links when I get home, I don't have them saved on this computer--so check back later. :)

Others seem interested.

Here are a few links to get you started.
If you decide to really go all out and start pulling all the interior panels, do yourself a favor and go to Ebay and get a shop manual on CDrom. (5$)
Knowing where all the clips and screws are is 80% of the battle.

I have had my EJ1 interior completely gutted numerous times. Having that manual would have saved a lot of time and frustration the first time I did it.
A small pick-set and a couple of panel-removal hand tools will also save you lots of time (versus prying on everything with a flathead screwdriver), prevent unsightly gouges in the plastic (from the aforementioned screwdriver), and you are less likely to break panel clips and the small plastic tabs. The end-result being that it will go back together nice and tight with no new rattles and scratches.

Here is an example of trim/panel removal hand tools:
http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=12812&group_ID=1793&store=snapon-store&dir=catalog
http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=12817&group_ID=1793&store=snapon-store&dir=catalog

and a basic small pick-set:
http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=9227&group_ID=1067&store=snapon-store&dir=catalog

Don't be scared away by the prices. Snap-On tools are notoriously expensive. You can get these same tools at Sears for a third the price.

Now for the links to the sound-deadening help pages:

this link is a huge help.
http://www.sounddeadenershowdown.com/

and this is a good thread on MP3car.com
http://www.mp3car.com/vbulletin/car-audio/79714-sound-deadening-liquid-vs-mats.html


...and my favorite quote regarding sound-deadening:
"You will also be adding some weight to the car. In my case, just over one hundred pounds. I choose to look at this as the weight reserved for one super-model. Since it would always have gone unused anyway, it was available for this purpose. "
