Whats the minimum amount of deadening one should do?

Well...my car is a 350z...and I am contemplating putting some sound deadning in the trunk, and in the doors...what would be the least I can do, while still getting good returns...I'm not about to pour liquid everwhere and put multiple layers in everywhere...I just want less road noise and want to find a happy medium...

Thanks!

Doors and trunk is a good start. Than you can slowly add from there if its not enough. A little can go along way if applied properly with diminishing returns the more you add.

Also may look into a closed cell foam to help with the deadening.

Well I was thinking of just putting the closed cell foam just behind my speakers...second skin looks like what I want, but kind of pricey...might consider raammat

second skin is the shiz

i would listen for my problem spots first. wheel wells and doors are usually the worst.

my floor in my car was pretty bad

well basically my enitre car was loud so i did the entire car =)

but deading the doors was magical. I did 4 layer...yes 4 on the rear wheel wells and it helped out quite a bit

the car is an 06 tc
