dynamat ?

how many sq ft of dynamat is need to do a double cab taco?
yes i used the seach button

 

I am not sure on the square footage, but I used two extreme door kits, an extreme trunk kit, and an extreme bulk pack. I did two layers on the doors, one on the inner and then another on the outer portion. Made a huge difference in the sound of my radio and really cut down the road noise, even with studded tires at 75 mph.
Also, Dynamat says that it costs around $1,300 for a full covering of a Tacoma, but I got it all from Amazon for about $350.

1 box of this will do all doors and the back wall. Don't bother with the floor.
Don't double this stuff up anywhere. It's not a sound proofing material. All it does is stop metal from vibrating and making noise. Add a small piece to a metal baking bowl and hit it with a spoon and you'll see what I mean.

Get the encolite to stop noise and the MLV if you wanna go further.

 

Here is a good shopping list of material http://www.tacomaworld.com/forum/audio-video/63934-sound-deadener-show-down-tacoma-kit.html

Don makes some really good stuff and good price for it, Rick at Ramaudio does too and give a Tacoma World discount.
