Stereo & Electronics - Anyone dynamatt the whole car- worth it?

I was thinking of putting one layer of Xteme dynamatt inside of the car. Taking out the seats and carpet and laying the entire car including the floorboard, doors, side panels, hatch, spoiler... everything. Will one layer be enough, will it do anything to silent the road noise? If it is a 10 without it what will it be afterwards? It will probably take about 5 door kits to do the whole car. Even at cost it is going to cost me about $200. Is it worth it? This car is a daily driver but I also take it to the track and street race quite a bit. Is it worth the added weight? I'm guessing an easy 50lbs.

-What areas will need more than one layer and how many?
-Will doing the floorboard help any at all?
-With the T-tops and the crappy unsealing windows, will it just make those leaks more noticeable?

I think you brought up the best question on this topic yet. Yes it will make a difference if the time is taken to be sure that solid contact is made between every inch of mat and car. But you will notice all kinds of little noises that you couldn't hear before. I went through all kinds of different materials in different places & got pretty close to the quiet I was going for. Then I noticed all kinds of little things. The spring on the ebrake lever was tinging, the bottom bar on the swing out cupholder was rattling against the console plastic. The rear sail panels were squeaking against the rubber, & of course the lovely seal against the ttops. Also in my case, there is a mystery metal tinging from somehwere behind my passenger air bag. Some foam & electircal tape solved the ebrake and sail panel issue. Heat shrink for the cup holder. I made new seals for the ttops. I really don't think the time/result ratio is enough to take off my dash to find a ting.

Dynamat Extreme is a good product, and i'm sure it works well, but does anyone know about Fatmat brand? I see on thier website they are selling 100 square feet for 99 bux. For $200 I could layer the whole car front to back, with several layers in a few places. Does anyone know about this product?

I will be laying 70sq feet of b-quiet Brown Bread down sometime within the next week and a half. Ill keep you posted. www.b-quiet.com (http://www.b-quiet.com) :secret:

Myself, CANNIBAL and some others used ac duct insulation from lowes. Its cheap, light, and makes a huge difference. I had some pics but my site is MIA. Added 15lbs total, did the entire car, cost $15 per roll ( took 4 rolls ).
