Has anyone here run dynamat extreme in their truck? I'm talking the entire cabin. I'm curious as to how much it'll kill noise, both the road kind and stereo vibration. Also what did it cost you to have it put in? Thanks for any input!
I have it on all four doors of my Durango. Not the entire cabin of a Dak like you're referring to, but there was a reduction in road noise from where I always noticed it the most. Additionally, it makes the speakers sound better somehow. I don't get any rattle at all now.
I got it when I first got my D and was putting in new speakers. Did the installation myself and it *seems* like it was somewhere around $175... can't remember the amount.
