This was my project last summer. its all fiberglass except the bottom which is fiberboard (i now know i should have used MDF, but the fiberboard seems to be doing a good job). the components are a 330w blaupunkt velocity series amp, a rocksford fosgate 1 farad cap, and a 350 rms polk momo 10'' sub. it fits nicely in the back, music is being pushed to it by a pioneer 7900BET (think thats what it is). hits hard enough that i keep the head unit sub gain on -15 out of +20. i like it alot, i think it adds a nice touch to the trunk. im starting to track this spring so it may be time for it to go.
