would 2 ED Kx 10" subs in a sealed box be louder at 225w each.. or a single vented RE SE 10" at 450w...
and if i get the RE SE i may consider getting a jbl 600.1 instead unless there is another amp that would put 600w into the RE SE for under $185 + shipping
edit: how would hte SQ compare between the two as well as the SPL
