Polyfill a NoNo

if it's so cheap, just do it and let us know how it turns out.

I'm in agreement! Stuff it! Stuff it! Stuff it! Stuff it! Fry! Fry! Fry! Fry! Fry!

It doesn't dissipate heat... It absorbs vibrational energy (read: rear sound wave produced by the speaker). It actually transforms some of the vibrational energy INTO heat. Basically it does the exact opposite of what you said.
And there is a difference between the stuff you buy at wal mart and the stuff sold at parts express - the stuff sold by parts express is denser and better suited to its purpose.

I yanked the stock sub out, Then i went into every box and epoxyd every box seam I could find to make sure its airtight cause sometimes those prefab enclosures you can never trust, then i DID stuff the box with a 1 pd bag of polyfill and it made a noticible difference, im pretty impressed with it.

The stock sound system is fine for me, I drive a modded SRT4 so I dont want to weigh my car down with car audio stuff thats low on the priority list so i figured ide just maximize what i have

for tests on different types of fill, like polyfill or fiberglass or dacron, etc. refer to the Loudspeaker Design Cookbook.
