Anyone using Dynamat to reduce road noise? Options

[GotToyota]

I'm not sure about you guys, but my Celica has a load of roadnoise, especially in my doors. One part is that my Rockford speakers have too much bass, and the other is the vibrations that come from the door when I'm driving. Now, I know that Dynamat actually dampens noise and vibration, so I was thinking about buying the two door kit. Has anyone used this for this reason, and gotten good results?

For deadening the road noise, i used lining from home depot or lowes. I used the lining the use for deadening a home water heater or wall insulation. INstead of using the fiberglass one, i ended up using the cotton one and cutting them for fitment under the overhead setup and inside the doors where the speakers are. It helped lessen the road noise. It is a cheaper way of doing it and it sure helps with keeping the temp inside warm in the winter and keeping heat out with a/c on during the summer. Its been working for me. Going on 3 years strong.
