"You have to get at least 2 subs in there. Honestly, 2 sounds a lot better. I say two 10's also. If you are only going to do one sub, I would say one 12, but make the box volume small (near the minimum) so it will be a bit more precise. The box makes a huge difference."

a) yes, two subs will be louder than one, by approximatly 3dbs (assuming the same power being delivered). this also assumes that the acoustical phase alignment is perfect, which is impossible. 2 is not not really better than one if you have to sacrifice enclosure volume to accomidate them.

b) 10"s are no better than 12"s, and vice-versa. the difference between the two sizes relies on the fact that a 10" with a small box that is "X" large will sound great, while a the same "X" volume w/ a 12" sub will not sound too great. richard clark put it perfectly when he said there are three factors to consider when choosing a sub: small enclosure requirments, SPL, and efficiency. you can choose between any two of the three, but not all three at once. its very asmovian.

c) intoduce yourself to something called "q". comlience plays a huge role in the way a sound system "works". suggesting a small enclosure as a general guide is just wrong. as ive said before, the "tightness" or "precision" of acoustic response relies on matching the mechanical properties of the driver to the physical properties of the enclosure. it also relies on the phase alignment of the driver(s) to the environment in which it is playing. do some reasearch into what enclose sounds best for the particulare sub, and trust me when i say the best acoustical coupling of the sub to the cars environment occurs when the sub is backfiring approximatly 6-10 inches away from the back of the trunk.


ive tested out numurous subs/enclosures (as well as studying acoustics in general) in the eclipses environment and this all comes from my personal experience.
