2 amps and more work?

Not necessarily, but that is a loaded question. It depends on what speakers
you get and what goals you have for the system.

I like setting up the stereo and everything but if
it's gonna start costing me then I dunno.

Well, that answers question one :-) What it ends up costing is entirely up
to you.

Was wondering also what would the
best kind of box and set up would be for 15's... thankz

Depends on the speaker. Some are designed for sealed (easiest to build),
others for ported (more difficult), and if you have scads of room there is
always bandpass (even more difficult). Then you can get interesting with it
.... isobaric, aperiodic and such (but these require a fair amount of theory
knowledge to design properly)
