Sound deadening material

[ShastaBlasta14]

I need some way of deadening road noise and a little ghetto rattle from my subs in the trunk. I dont want to buy that dynamat stuff, its way too expensive for something that just looks like a roll of foam to me. So, does anyone know of a cheap do-it-yourself type material I can line my trunk with, and put under my interior carpet that will deaden road noise, etc.?

Dynamat is more tar than foam an it does do wonders. ive used it on a few panels around my speakers, and it helped take away road noise too
im sure theres a chepaer way tho
