I got bored last night. I knew I had nothing to do when I was headed home from work, so I stopped at my buddies stereo shop and picked up the Big Pack of Xtreme Dynamat. 36sq. feet of it. I'm not sure if I went a little overboard or what, but I ended up using 7 complete pieces and a few inches off the 8th piece.

For some reason I thought that this much Dynamat would be enough to do my entire trunk and the rear quarter pannels. I just wanted to know if anyone here had done it themselves and could remember how much it took to do their cars.

 

I used 50 feet of B-Quiet to do the sedan's trunk and under rear seats in double layers.

 

Yeah I bought the B-quiet 50sq feet pack.... covered basically everything I can from the rear seat back including top shelf.... though I added more over the wheel wells. Also used B-quiet L comp over everything to top it off. For the doors I just bought the Dynamat extreme door kit for them. Made a good difference in sound and also made my door heavier than it already is Made a big difference in sound ( my old tires were really loud back then ) and also improved my stereo.

I didnt wear gloves when I installed so washing my hands afterwards was hell

 

I used eDead, 40-50 ft for the trunk/rear seat. Another 30 for the 4 doors. 36 ft of anything will go real fast.

 

yeh i used the big pack xtreme and its only enough for my trunk too...took for like 3 hrs to do everything

 

I was starting to think I was over killing it. I didnt expect to go thru it that fast. I covered just about everything. i put a few pieces on the botton of the rear speaker deck, but I didnt completely cover it. Im holding out doing hte quarter pannels until my Infinity Kappa's come in.

I did see someone's post about the insulation inside the quater pannels. anyone try this? is it worth it? seems like it would be a good idea.

 

I used about 75 sq ft of edead and some home insulation to fill the rear quarter panels

 

took me about 60sf to do the trunk, trunk lid and rear quarter panels. 20sf to do the rear seat area and 20sf on each door. so to do the whole car excluding the floor and roof I would say around 120sf.

 

i have about 120 sq feet of edead v1 and v4...but i dont have a G...

to do both doors, trunk, trunk lid with one layer, you would need about 60-70sq feet, whcih obivously can get VERY expensive if you use dynamat extreme.

i say use edead or Raammat, much cheaper

bing i still want to do this... will pm you later about it

 

hahah, sure, just let me know...though dampening is something thats a lot more economica to do yourself, its very time consuming so costs moeny to have someone do it

Sound deadening is a pain but well worth it if you do it yourself to save some costs.

 

I sound deadned my car using Hushmat Ultra (www.hushmat.com). Its less expensive than Dynamat and it is MUCH EASIER to install. You do not need to clean the surface that you are sticking to and it mouldes easier to the surfaces. I can sell you a 58.1 sqft. bulk kit for $280 plus freight ($399 retail). They also have door kits for $65 plus shipping ($89 retail).

does doing this reduce road noise a lot? ive been considering doing this for a while since it gets pretty noisy in cabin at freeway speeds.

 

yes, it does quiet it down quite a bit, you'll notice it immediately. BUT, it doesn't make the G silent. The car is just too damn noisy to start off with, the exhaust and tire noise is just too much for it to overcome. On the other hand, on my Lexus which was a quiet car to start off with ended up being very quiet.
