sound deadening

does anyone knwo of anythign that can be used for soudn deadening that isnt dynamat or stuff that cost a arm and a leg. like any kind of foam or anyhting.

there is a recent thread where this should be discussed, rather than creating a second on nearly the exact same subject... imo, dynamat is the way to go, theres a reason why it's the stuff everyone mentions when talking about sound deadening.. but if you really cant afford it, be prepared for a product which may not be of the same quality.
