When you say 8's, do you mean the mounting depth, or box space? Theres starting to be some tens out there that can be used in VERY small bokes, course, if your mounint hole is only for 8's....Anyways, this is where I got my sub, its a 12" and while a bit expensive, has generally been regarded as one of the best subs on the market
Might look into the 10....

Bleh, forgot to add, at Adire, its the Brahma sub....
