Just wondering if anybody has removed the spare tire and added Dyna mat or poly-fill to improve the sub quality? I'm happy with the sound quality for a factory sound system, but my gut feeling is if I fill the spare tire void with poly-fill (basically synthetic pillow stuffing) and put the spare tire board/cover back on it will hit a little deeper. Figured someone has done this already and don't want to waste my time if it didn't make much difference.

 

I have though about dynamatting the whole trunk someday as well.

 

I did it, but unfortunately don't have a before and after story for you. Didn't have a sub before the dynamat was installed, and what I'm running now isn't exactly "serious". Just a BassLink.

I will say that from inside the cabin I don't hear any exhaust noise when accelerating. All engine.

My hope is that the deadening kept the base in and exhaust noise out. I also covered all 4 door skins.
