3 12's would be louder.. but that sub strongley recommends a sealed box remember that... but yes the 3 12" subs would be louder but then again it depedns on the amps you get.. if your underpowering the 3 12's and powering the 2 15's perfect.. the 2 15's so make sure your watts add up right

1200 watts is too much for both set ups the 3 12's should be 900w rms and the 2 15's should be 600w rms

surface area of 3 12s = 339.12
surface area of 2 15s = 353.25

so 2 15s will actually be louder under optimal conditions

two 15"s would be louder than 3 12"s, more surface area as stated above. and I would put them in a ported box rather than a sealed one. it would get a lot louder., but the box would have to be about 6cuft at least.
