just wanted to provide an update on the project. i've now sealed off the trunk noise by fabricating a sound barrier made of 3/4" mdf material with reflectix glued to it. on the side that faces the inside of the trunk, i've put some sound deadening material as well. for the presents shelf, i also fabricated a sound barrier using 1/4" mdf with reflectix. i noticed last night that the speaker cover on the presents shelf still rattles, so i figured i should put some sound deadening material there. just have to be careful that it is not so thick that the shelf cover doesn't fit any more.

i've also decided to take off the interior side panels where the back seat was. when i tap on them, there are rattles and a bit of a "tinny" sound. it could use some increased density there as well.

the sound inside the cockpit seems to be much more pure. by that i mean, less of the trunk, rattle and road noise, and more engine rumble. since it's winter, i can't really say anything about heat, but i presume that the reflectix will reduce that when summer roles around.
