Just wondering how well Dynamat works to dampen car rattle.
Does Dynamat make a difference?

Well here is something I am sure not everyone has heard of or tried. I used house insulation in the rear walls of my Integra...not a lot of weight and road noise is way down and more base out of my stero. Oh, one last note: I would not put it in your doors...might make the windows have problems rolloing up and down.

i think it helps stop the rattling pretty well. i have it all on the trunk floor and also on the back sides of the tail lights. heres a few pics.

source_money - I did my trunk but rather coverd every sqaure inch. The most noitceable part would be dynamtting the wheel wells. Though my bumper rattle still will not go away. Aslo we have the same rear bumper......does yours rattle?

In my old Teg I fatmated everything except the door panels and dash. It sounded awsome here's some pics

Damn that old setup had awsome sound quality and was very loud. Got my a damn ticket.

I actually rattle proofed and sound proofed my teg over this weekend, and as already mentioned, I used sound insulation for a house. I removed the back seats/panelleling and stuffed it in mass quantities into the empty body cavities all around the rear so far, including the hatch, under the seats, under the spare, and like I said, a ton between the rear panels and interior arm rest area and over the wheel wells.
After driving without anything but the tin back there, its 100X better, hardly any road noise, sub sounds much much cleaner, literally zero rattling inside or outside, even tho my entire hatch and doors flex from the air pressure. Cant wait to do the same to what I can on the doors and firewall area. No difference in performance from what I can tell, its fairly light considering the improvement and amount I used. Also very cheap, one bail cost me $30 and I've used about 3-4 sheets.

Okay, with all the different products here, what is the absolute best material (keeping in mind noise reduction and not way too much weight) to line wheel wells (under the paneling in the back i assume), the trunk, doors and floor of the car in order to reduce road noise?
Price is not a concern. I just don't want to use something too thick and weight too much if i can find something more expensive that weights less and does the same job.
I want as little road noise as possible.

well weight is what stops vibration, so your gonna have to add that one way or another. Maybe liquid sound deadner would be good for you http://secondskinaudio.com/seocnd skin has alot of differnet types of materials for quiting your car down.

Okay, i got a few more questions after i searched and didn't come up with anything.
When you say "wheelwells" do you mean the inside of the car or like on the outside of the car? Like taking out your fender liners and laying the stuff in there? Or taking out the plastic in the trunk and laying it under there?
If i lay this stuff in the doors, and under my carpet like the pics on the pg 3 but lay it everywhere i see metal, so it looks silver EVERYWHERE, would my car be comparable to a lexus in road noise? Everybody keeps saying it's gonna be more quiet, but i'd like a reference you know.
I know it depends how much i lay but i'll say everywhere, a single layer.
After looking at a bunch of material, if i'm doing this, i'm gonna go with dynamat extreme.

inside the car.
i doubt comparable to a lexus. our cars contain relatively thin and flimsy shells to begin with. it will still be a noticeable improvement. a lot of noise will also be coming in from the firewall, which is a tough spot to get to if you're planning on layering that as well.

Last Friday i tore the whole back portion of my interior out... Since the materials were free to me i figured why not cause it couldn't hurt to try. I started by glueing 40 oz jute (a similar padding like material found under the rear carpet, except that was unidic which really sucks compared to jute) on the whole floor from the carpet back (under the spare and the jack as well) and I also put some on the back of the trunk over the tail lights. After doing this, i filled the gap between the quarter panels and the inside wall where the speakers mount with another material, then lined all the gaps with more jute.
While its no dynamat, it offered awesome sound deadening with the benefit of insulating properties... Didn't add too much weight, but i would bet more than some dynamat, but I could really care less about a few extra pounds. From the outside of the car, you cant even hear my rear speakers when they are at full volume. Driving the car has totally changed because i can barely even hear my exhaust with the windows up, let alone vtec's loud buzzy sound. I can no longer hear any rattles from the back of my car such as my rear bushing squeak that used to be really loud. Now the front of the car all of a sudden seems loud, and i only have an icebox up there so it doesn't really get that loud.
on another note, since i lined my spare tire area, it now has a semi finished look under the carpet, and i can now put stuff in there without the worry of extra noise.
Oh, i forgot to mention that i still don't have my A pillar and rear quarter window trim peices installed because im wrapping them and will be pulling the headliner in a day or two... so i would guess it'll still get quieter since there is a giant gap over the back paneling. Sorry to clutter this thread up with yet another idea, but I think its done an awesome job sound deadening so far, monday i'll try to get pics to show what all i did since i should be pulling the interior out again.

theres no need to cover whole car in dynamat u have to cover the parts that are actually resonating an example plastic vs wooden or metal speaker enclosure
plastic is thin and flexible easy to flex so it vibrates pretty much at every frequency ,wood is thick light and its resistant to vibration because it thickness to a point it will still vibrate at higher volume the metal is heavy compared to plastic and wood but its pretty stiff so weight and stiffness absorb the vibrations also the shape plays a role thats why the doors and rest of the car have no large flat areas or if its relatively flat and without bends it is supported bu something to see what im talkin about turn the speakers up and put ur hand on the outside of door in different places u will see the difference
carpet doesnt stop vibrations it absorbs the sound (including your speaker sound too) which can be good in some cases also leather interior sounds lil more crisp because of hi freqs not being absorbed by cloth seats
another thing that everybody forgets about is the plastic interior pannels as with speakers plastic is more flexible than metal and resonates more so check them too
