i am considering put in some either brown bread, fatmat, or ratmat in my car (doors, corner panels, rear deck and eventually the trunk. ) and if i am crazy about it the floor and roof.

i don't need opinions on the perfect product but rather your results from the experience.
i am looking to improve the overall sound quality in my car as opposed to stoping rattles. (i am fortunate enough to not have any!!!!!!!)

have you guys noticed a different in the quality after installation??? what is it you have noticed about the change?

i know this topic has been discussed alot but not for what i am asking about.

thanks guys

i didnt notice an audio performance increase after deadening my doors. however, they sound awesome to slam shut deadened, like slamming shut the door on a mercedes.

The doors are easiest to deaden with spray on rubberized undercoating, you can point the nozzle between teh cracks of the doors and get the entie skin. dont forget to mask off the window and car if you do this though.

I also am a big fan of expanding foam as a deadening product. it goes anywhere there are large open areas, like that space between the frame of the car and the rear quarterpanel, or between the trunk skeleton and outer skin, or hood skeleton structure and hood skin. It eliminated rattling anywhere I put it.

The basic premise of deadening is if it rattles, deaden it. if it dont, dont fix it if it aint broke!

find the rattles, eliminate them. then drive around and find sources of road noise and eliminate those one by one, too.

good luck!

Sound deadening is great, it for one stops resonance that kills the whole music experiance. Anything that rattles can be deadened, or at least made unnoticible to the naked ear. For the mat type deadeners, they are a pain in the **** to install, but well worth the time. I like fatmat, mainly because it's the cheapest I have found. It works as well as any of the others in my experiances. Some others you may want to try are raammat, second skin, brownbread, etc. I am almost against dynamat, not because it doesn't work, but because it is rediculously priced. You might also want to look into some liquid deadener products, to fill in places that teh mat deadener can not get to. And as rabbit said, expanding foam is a great, and rather inexpensive deadener. And you can cover a lot of area with it rather quickly.

Dynamat is the best because it doesn't smell. Believe me it's worth it. I've done all four doors, trunk, and rear deck. It does make a difference. I also did the floors with brown bread. Must road noise comes through the doors, because they aren't deadened at all. The car actually has some crude sound deadening on the floor and trunk. Doors have a plastic sheet.
