subwoofer selection.

Ok I have a pioneer gmx962 amp ie 150x2 or 380x1 rms running at 4 ohms. The problem is which subs I should get. Should I get 2x10inch pioneer(175 rms) or 1x12 inch pioneer(200 rms)? There is also a store out here selling jl audio subz quit cheap. There was a mean looking 15 inch WO being sold for 70 bucks and a 12 inch of the same model going for 60 buckzWhich of the above should I get to pump clean deep bass?:help::help:

get the 15" W0.

sounds like a plan to me .... one 15" sub should be fine
