I was thinking about how I could make my stereo better. I looked at amps and speakers, but someone told me about this dynamat stuff and strongly recommended it to me. Has anyone used this stuff on their msp? If so what are your impressions?
 
I always thought that stuff was just to silence rattles and vibrations...
 
Actually, It dampens vibrations from the outside and inside so the ride is quieter and the speakers work more efficiantly
 
Hmmm is it hard to install? I never really paid attention, because I never cared about my stereos in my former cars...
 
it comes in large sheets with self adhesive backing...you actually can go to home depot and buy their heat shields there and it works a lot better..and its also like 1/3 of the price..just make sure its warm out when you stick it in...just lets the glue mold around the trunk and wherever you put it better.
 
Haha the only reason I'd be using it is to quiet the road noise, but then again I wouldn't even know where to put it. Does it look ugly when you put it in? Or do you put it in concealed places?
 
You put it behind the door panels on the metal and in the trunk under the mats and wheel wells
 
Wow sounds like a few hours worth of pulling interior panels out and such. No big deal. I might consider doing it sometime in the future...
 
thats what i heard too but they say the spray is a real big mess, i havent seen it tho. i'm planning to have it dyna'd or w/e sometime this spring when it warms up, god mine rattles like a caprice or something... sucks...
 
I've partially dynamat'd my trunk and I wasn't too pleased with the results. If you DO decide to do this, buy a cheaper brand. Dynamat is WAAAAAAAAAAAAY too expensive compared to some other products which work just as well. I'm moving this to the car audio section so we can get more feedback.
 
when i bought my msp. the previous owner already dynamated the whole rear of the car and the inside the trunk. i'm glad i didnt buy that overpriced stuff. i still hear vibrating tin noise.
 
there are cheaper alternatives than dynamat. B-quiet, edead, fatmat and some others.. those were on the top of my head. it helps. to put it in the doors you have to take the door panels off. you have to cut teh stuff in little piecs and stick it in there. usually like 1-3 layers is what people do. I used a heat gun to warm up the pieces. makes them mold and stick better. takes awhile but it is not hard at all. then I took that plastic liner off the door and put some on teh inner door to.
 
I used FatMat on the rear hatch area of my P5 and it made a huge difference. No more spoiler rattle, no more rattle anywhere back there except the bumper, and I have 2 12's pushing 700wats RMS. I'll probably do my doors next. :)
 
www.selectproducts.com has cheaper stuff
www.mcmasters.com has cheaper stuff (do a search for high temp mastic) this is what dynamat is.

www.bquiet.com has cheaper stuff then dynamat

use a heat gun to put it on to get the most out of it. this stuff is more for keeping vibrations down then keeping out road noise, if u want to keep out road noise, find some sound absorbtion material for under the carpet.

this stuff is like anything else though, the more u use the quieter things will become wich is a good thing, i used over 300 sq. ft. of it in my funfire.
 
I don't know that it will deaden the outside noise that much, but it does keep things from rattling and vibrating inside of the car.
 
I used the Circuit City brand Tsunami (made by metra) since I work there and IT KILLED the vibration completely on my rear wing, I also did use Dynamat on the door panels.

It's something I reecomend and if you do decide to do it, have a blow dryer handy, because that stuff works better when it's really hot and it alllows you to push in the dynamat in little spots.

overall, it was a good $15 investment.

BUt don't go to Circuit City to buy, WE CHARGE WAY TO DAMN MUCH if you not an employee.
 
By the way it advertised that it works by turning vibration noise into low heat energy under your car, thus only the music can be heard,

I think thats a bunch of BULLCRAP:bs:

It's just freakin Cokin on some aluminum sheet
 
basically what it does is add weight to the object so it takes more energy to vibrate it. in a nutshell. kind of like when u have a panel rattling and u push on it with your hand, you are now mass loading it. (adding your weight on it to make it harder to vibrate.)

as far as deadoning road noise, anything placed between u and the noise will have some level of absorbtion. carpet that is a foot thick will stop more sound the the carpet in there now. i tend to use those waffle foam pieces for that. for under the carpet i dampen the floor then add those thick insulation carpet pieces u see under your carpet.
