lulz were had ITT.
OP, if I were you I'd look at some 8" midbasses, if you can fit them. You'll need less excursion to get good output, thus reducing distortion from the speaker itself. I'f you're dead set on going with 6.5's, then the Exodus Audio Anarchy is has probably the most stroke out of any 6.5" speaker out there.
