do your ears pop when you close the doors ...
I completely agree. I'm gonna do the same thing but I think I may use other products. CAE products are just as good and lighter as well.

You should see the stuff I put in my 911.
15-30db drop in transmitted sound, but its expensive. B-Quiet Lcomp. That and four or six square feet of xtreme dynamat got it to the point where you can talk to the passenger in the car if you both talk loudly.
The S4 is the first car I've had that I didn't dynamat the doors and rear shelf at a minimum -- it really does help sound a lot.
There are two fundamental types of sound deadening for cars -- true deadening material like dynamat which shifts the frequencies down on the vibrations by adding mass to the surface they're quieting (best for rattles, etc), and sound absorbing material like the Lcomp. The former is important for car audio purposes because it stops rattles, the latter is handy for loud cars where you really want to block sound.
