I recently installed Dynamat in the rear trunk area of my Base 6MT and it really eliminated any noise emanating from behind the seats. Very satisfied. I have a lot of Dynamat left over. Road noise I get now seem to be coming from under the seat area - or perhaps the doors. So, I am thinking of pulling the seats - lifting the carpet and installing the Dynamat. I am not planning on pulling the center console, but instead doing one side at a time. I cant see a lot of value in sound insulating the area under the console.
For those that have pulled up the carpeting:
Do you reapply a spray adhesive when reinstalling the carpet?
I am assuming you leave whatever factory sound deadening in place.
If I have any Dynamat left over - I will pull the door panels - any advice would be appreciated.
Thanks in advance, and a Happy New Year to the group.
I haven't pulled the carpet but I don't believe it has any adhesive, only clips. I used both the boom mat and spray in the back but not nearly as quiet as I'd like it to be.
I am pretty close behind you on this. I am pulling the seats out in two or three weeks to have them reupholstered in leather(got the seat leather in Christmas eve) at a shop. I have the Dynamat Dynapad and the dynamat Xtreme sitting in my garage as we speak. I have done the back of the car and the area directly behind the seats with very good results. Not looking for it to be quiet like a luxury car or anything, just so I could better enjoy the radio and longer drives in the car. Let me now how it goes for you if you do it. I have not done the doors, other than the speaker area, but I read it does make a difference there.

Will definitely update things as I go with this. Likely I will do this next week.
Take a few pics and post them and let me know how it goes. I am hoping to get up under the carpet after the seats come out without having to go to crazy removing things. My foot rest area gets pretty hot as well and a bit more insulation there would do no harm!
Jim might want to try to wrap the exhaust in that area, or put a shield over it, I'll be doing that when I put the supercharger on so I can get rid of some of that heat.
Since you're in AZ, I'll chip in that after the floor pan, doing the roof in several cars I've owned has yielded an improvement in heat reduction as well as noise.

I have owned my 2007 since I bought it brand new. After 13 years, I feel lots more road noise coming from the rear. I was thinking about Dynamat but not sure if it's worth it.
I am a latecomer to the Z. But the roadnoise was definitely reduced with the Dynamat. If it never bothered you before - could it be your tires have started to be the source of the noise?
So, I went ahead and did the passenger side with Dynomat. As requested I am including some pics. I did not pull the console, and instead just pulled the carpet back to access the passenger side floor. Some lessons learned- break the seat bolts loose (14mm) with a wrench or breaker bar - my electric impact tool could not break them loose. I removed the seat back bolts first and then the front. Getting the wires under the seat disconnected and unhooked to get the seat out was a little bit of a pain. Unhook the battery - even if you dont have side airbags. I skimped a little on the Dynomat since I need to do the drivers side next. I hope this is helpful.
When I was doing the Dynamat install, I pulled the panel behind the drivers seat, where a subwoofer would be installed (I assume). Is there an aftermarket door or access panel made for this? There is a lot of unused storage back there.
That's interesting. Once you pop off the plastic cover behind my driver seat you just have a big rectangle opening. My car is a 2005 enthusiast model. I actually have my speaker amp mounted back there. It is just a big open area. I ended up putting the same stuff down in that box that you have and also the foam sound deadener which helped a lot. I find it interesting how the model years and styles of cars have small variations in the design of things.
I stripped my entire interior and put dynamat everywhere when I did my audio project. I came to the conclusion that tires play a bigger role than dynamat. Switching to hankook ventus v12 evo
made a more noticeable difference than all the days spent on dynamat. I am not saying it is useless but I suggest you look into tires when you are all done
beezee - thanks for the reply. Currently I have Michelin Pilot Sport tires, when they need replacing a quiet tire will be my priority. The Dynamat made a substantial difference, Thanks for the recommendation on the Hankook ventus v12 evo - have you installed them, or is that what you are going to?
Also running the Michelin Pilot Sports on 19" wheels. I also have a set of Federal tires on some 18" OEM Ray wheels. Don't recall a big sound difference between the two and that may say something as the Federal's are said to be "noisy" . Really though, while I hear the tire noise, not something that bothers me much. What really bothered me was the VERY loud exhaust that the car came with. Once I replaced that and put in the dynomat I could actually start to hear the tires. LOL

I have had them for some years now. I don't drive much though.
They made a significant difference and plan on buying them again when time comes for replacement
