I just put dynamat in all 4 doors and on the rear panel behind my seat and it made a huge difference in road noise and tire whine. I did not go as far as removing all the seats and carpet, too big of a job for me, but this stuff really works. The other reason I installed it was due to the new system I put in my truck. I thought it might help improve the sound quality, and it did. I recommend this without hesitation.

 

How much did you used to complete the job??

 

It ain't that bad to remove seats and carpet.

I did the doors like you and the floor and back wall make a difference.

Especially the back wall because it is pretty flexy .
If you have woofers(sounds like it) this panel is going to deflect and reduce your thump potential.

 

I bought a 100 sq ft roll planning to do my wifes explorer when I upgrade her sound system. I probably used a little less than 1/2 the roll on my SD CC. I have 2 12's behind the seat and they hit soooo good I really couldn't tell if I lost any or not.
