Dynamat, Anyone done it? Options

[PowellCelica]

I realize more then a hand full probably have but i'm looking for a wright-up or something. Or just some picture of it being installed. Where did you put it? How much of a diff does it make speaker wise? Road noise wise? Engine wise? And even closing your door? I'm really looking at doing this because i personally can get this stuff cheap through my friends shop.

[Coomer]

I've got a bunch of stuff that's exactly like Dynamat Extreme, but without the Dynamat logo and the outrageous price. I've got about four to five layers on my trunk lid and underneath my rear deck. On top of the rear deck and on the side walls and bottom of the trunk, I've got two layers, and on the back wall of the trunk, I've got about three layers. On the front doors, I've got a layer on the backside of the door panel, and one on the inside of the door. It has made a huge difference in the way my car sounds. No more rattles, and you can hardly hear my system outside my car.

i'm with coomer


i have almost the same amount of layers that he has and wow does it change

i on the other hand used dynamat extreme.

you can get 36 sq ft for 99 bucks on ebay.

just in comparison a trunk kit at a stereo shop is 12 sq ft for 150 bucks.

ebay is the better deal

dont get brown bread either have many friends with really bad experiences.

the 36 ft that i had was enough for one layer on each door, and the trunk floor, hatch lid, and back and sides.


its definitely worth it.

almost eliminated my rattle with my huge system (3 JL W7's and two planet audio 2250 amps)

all the car did afterwards was shake not rattle.

damn gt2gt4, your system sounds incredible

[YellowTwo]

gt2gt4: was the rattling annoying so u needed to get dynamat? or did u just know it would have better sound if u got some?

[SoundSlut_dotcom]

best spot to put it is under ur mat in the back hatech area.. or trunk area.

[Coomer]

[SoundSlut_dotcom]

yea rite on the metal

[Guest_Matthew_*]

6gencelicasrule: ya it raddle a buttload and i also knew it would sound better too. soo both


also soundslutdotcom is correct. i put it under the carpet like where the spare tire is, on the sides, against the back, on the hatch lid

also on the doors there is an opening to get access to your window but there is metal behind that and if you cut it in smaller pieces you can cover ALL of that too.

makes the doors shut a little firmer. they dont rattle at all. and you dont have to turn it up on the highway.

[PowellCelica]

Wow! I think i'll def. do some matting before i install anything! Just seems to be the smart way to go. Still looking for pictures though if anyone has any! Thanks guys!

Ahh bro never use dynamat or anything like it, the best thing to use is a bedliner spray.

If you need to fix a rattling quick, stick a towel near that area =P
I had to do this when I entered my first competition, the plastic in the hatch rattled against the metal, so we used a towel to eliminate it for the comp

Seriously though I would recommend using bedliner to anyone who is planning on building a nice sound system

I agree with PowellCelica that stuff works ALOT better than dynomat - period.. it also is great for custom jobs.

[PhillyGuy086]

hey coomer, what is the name of the stuff you use instead if dynamat. also where did you get it? can you pm me with the info.

[Drocay]

i was reading on some of the Audio forums and they were talking about some stuff called Peel and Seal which is used in roofing and they said that it was just as good as Dynamat exept that it cost near to nothing compared with the Dynamat.

[TRDracerGT]

I used dynamat and it worked great. First i cleaned my trunk with some cleaner and than layed it all around the wheel well and on the sides of my trunk. I had great results and the rattles went away. I highley suggest you get it or something similar

[AudioFreak]

Like TRDracerGT said clean the area well. Then for best results get some heavy leather work gloves and a heat gun. Dynamat and similar products get soft when you heat them up. I like to get it so hot that it's almost hard to handle with gloves. When it's this hot it sticks better and forms to all of the curves.

Someone said they had problems with Brown Bread. Personally it has worked very well for me. I think the heat gun maybe the trick.

i was in the hardware store and saw some of this thick rubber roofing stuff. it looked like it would work well at blocking sound. it was about 40$ for a huge roll.
