Do the Q's if you have enough room for a proper sized box.

LOL.... huh?!?!?!?

Those amps do 2500 rms, each 18" Q would be seeing roughly 1000-1300 rms

The Q's will be louder!!!

5000RMS is not to much for 4 Fi Q's

four 18's spl or not will get down and the sq subs will sound better.

Do you have air space to run four 18? if you go to small you will get real peaky

4 18 Q's. you realize you'll need about 24 cubic feet to run these though.

IF you want loud, why not grab some subs that have actually done something in the spl world.

The Btl's have made a mark in spl.. And 4 Q's would be absurd with great SQ. I don't see a reason to knock either choice, admittingly I would go a different route. But that doesn't mean that either setup wouldn't be loud enough for most. I would Definately look into the Sonance. Will be louder than the Q's, sound as good or better, and save quite a bit of space.
