Bought a huge pack for my Z, any tips on installing this? Hoping to stop the rattling and also to lower the road noise.

 

How many sqft is the pack?
Are you doing speakers in the doors?
For a basic install you want to do doors, wheel wells, bottom of hatch area. Cover like 75%(no need to completely cover, just need to keep the panels from resonating), then lay a closed cell foam like ensolite over the top of the matting.
For a more in depth install you could take out the seats and do the floors. Also the area behind the kick panels.
You don't need to do tons of layers of dynamat to get good results. You want to make those metal panels go "thud" when you tap them instead of "tink". Usually, just covering a good percentage of the panel is enough. Covering with a foam will help block out more of the road noise.

 

Awesome, good deal, thanks! I am going to cover the entire bottom of the car (road noise), the doors, and the hatch. Is there any reason to put it inside or outside of your speaker box? Also bought some Dynasorb for behind my front speakers.

 

Is there a cheap place to order Dynomat (sp) from? I was thinking of laying some down to help with the exhaust noise inside the cockpit.

 

E-bay has plenty of dealers. "Dynamat" is a trade name like scotch tape. I used 75 square feet worth of fatmat on my Z. It does take a couple of weeks for the smell to go away.

 

Thanks!

 

I would very strongly recommend "Rammat". The guy who runs it, Rick, is a super cool guy. I've used the product in a few cars. Very easy to install, adheres well, does not smell and it's a really good price in comparison to dynamat. I think it's about $99 for 60 sqft. You can also order ensolite which is a type of foam that blocks noise. Definitely worth it, the stuff doesn't cost much either.

He's an enthusiast offering a great product instead of a guy just trying to make a buck. Back when I had my WRX he wanted me to come down and visit so he could check it out and help me install the mat.

You might not need to do too much on the floor...I pulled up the carpet yesterday and it seemed like there was a lot of matting and bedliner type stuff underneath. Definitely do a good job in the hatch area. Besides the carpet there's really no damping back there.
Matting around your sub will help minimize rattles from bass.

 

Here's a quote pulled from elitecaraudio.com by Rick

"Yes, but you do not need to cover everything, mostly just the larger flat areas, curved and small flat areas are less likely to resonate. I use pieces a bit smaller than the area, rub it down well and then tap on the other side, it is sounds alot deader, that is usually all you need for that section. Move on to the next area and do the same, if any loose parts, matting them may be the best fix, depends on the part and how attached, etc. The mat I used on my Matrix front doors equaled less than one third the total area of the door panel.

There are some great posts on that site if you do a search for rammatt, etc.

 

+1 on Rammat. That's what I used. Good stuff.
