oh and speed racer, my 05 lux has sound deadening all through it, dash around tweeters, doors all through x 4 doors, rear parcel tray has 2 layers of dynamat (still rattles when absolutely pumping but bass cancels rattles out haha) and also my boot has dynamat in certain areas also. dynamat is def a worthy investment. i cant stress how much better your sterio and driving experience will be with it!. Even with the stereo off driving in silence is alot more quiet with the dynamat, less road noise etc. I can have my stereo on 28 out of 30 max, with all windows up, and people on the outside can only just hear the music through the doors, boot sounding like its about to jump off n run is another story haha. but yea dynamat= WIN!
