E46 Speakers sealing off rear Shelf

has anyone here Sealed off all those gapping holes at the bottom of the rear shelf with Dynamat and it increased bass response in your component system install?

right now i have 6.5 image dynamics CTXcs components front and rear and im trying to figure if sealing off the rear shelf with dynamat would make a difference?

Someone here posted, I think Solidjake, that they used old t-shirts. I stuffed mine with old t-shirts. It sounds a little bit better... well the sound is more in the car than trunk.

I may be confused here but you are trying to get bass out of 6.5's? Also we have an audio forum here where these kinds of questions belong.

Long story short yes it could in theory improve your low-end response, but I still don't understand why you wouldn't buy a small sub and install that instead.

Sealing the deck will not increase bass response from your front or rear speakers. The only way it would increase bass response is if you had infinite baffle subwoofers like JL Stealthboxes bolted to the rear deck. Then, sealing the holes would help.
