I just finished installing 15 sheets from 3 trunk kits of Dynamat extreme. The difference is amazing. To the point where I had to turn down the gains on my sub because it was severely overpowering my un-amp'd front speakers. I was able to do the trunk all the way forward to behind the seats and then the door panels with the 15 sheets. If I ever take up the seats or carpet I'll have to get some more or if I want to do the ceiling. In all, I think for an absolute complete install the car needs 25 sheets sized 18x32. Thats for head-to-toe; firewall to rear tail, and ceiling. Road noise is very very good now especially since my tires are acting very noisy at their last 20% or less tread life.
