Dynomat is readily available at any Best Buy, Circuit City, or other audio shop for a fairly low cost per square foot.

Brown bead is the best way to save money.
Me thinks its just about as good.
I did my doors on the 79 and made a HUGE difference. Will do the rest of the cad when its gets to that time.
