is it just me or has every post this guy made been to promote his shop?
anyways.
for under a grand I would look into something like the Kicker L7's. Then power the L7's off of a hifonics bx2005. If this is also going to be used for daily listening then I seriously doubt you are going to get all that loud though, MAYBE mid 140's with a VERY good box. With an SPL box, this set-up could very easily get you 150.

my comp is being gay and wont opne up anything now so I would use a Hifonics bx2005 (I believe is the model number for the amp, its 2000x1 at 1 ohm) for the L7's
