I currently have my trunk lid, and my passenger door sound deadened with Dynamat Extreme. It's not a bad price on sonixelectronics for a bulk pack. The difference between my two front doors is noticeable with Dynamat. The midbass is smooth and louder. On my trunk, it didn't totally eliminate rattle, but to the point where it just sounds like a little clicking is happening, nothing that would embarrass you. I think it's worth it.
