Question about sound proofing

[JDAN]

Hey, I have an AE92 corolla and i am not very happy with the sound quality in my car. I was wondering, if i wanted to line my car with some kind of sound proofing material what should i use? I know of soundproofing stuff like dynamat, but using that it would be really expensive to cover a big area. Is there some kind of cheaper material, not neccesarily of the same quality as dynamat, but still reasonably effective that i could use? and whats the best way to do it to eliminate wind and road noise? I assume i would line the inside of the door panels, line the inside of the firewall to eliminate some engine noise but what else? I'm not really sure what the most effective way of doing this would be...

go to the hardware store and get yourself some high quality ear plugs and plug your ears up while your driving .

Check out raammat60. www.raamaudio.com It's 79$usd for 62.5 sq ft. Same quality as dynamat extreme. Three rolls was enough to do my entire camry. Then after installing the mat lay ensolite foam or the foam lining that goes under hardwood floors. Also remember that most of the road noise that comes fromt the vehicle is at the doors and where the window seals up at. Make sure on the doors to do a layer on the inside door skin as well as the part of he door where your speakers mount up to. Put a layer of ensolite foam on both parts of the matted door. Also get the padding that goes under home carpet and rool it up an push into any space that might be letting noise come in.
