How many 10' rolls of dynomat would it take to double layer my car?

Question

I got a big car, Lincoln Mark VII

Answer 1

check out other sound deadening products online....you will find a lot of good ones out there that are a lot cheaper and work just as well if not better than dynamat.

Answer 2

You need to read more about dynomat. Its designed to stop the metal of your car from "paint canning" the boink noise it makes when your subs hit. The correct way to use it is to put small amounts in the centers of every panel not to cover the entire car. Dynomat makes a different product for sound proofing or sound deading the entire car it is to keep outside noises out and more inside noise in, but is spray on not dynomat.
