what are you looking for, sql or spl?
kind of OT, how do you like that amp? i just got an 18xxx and i was thinking of getting one.
You might be able to resale them and make a buck but your XXX will still have more cone area and excursion as well as equal or greater SQ.

I love this amp, I modded it myself it was pretty easy. Thats all there is to say lol it will run off 4 gauge but the manual recommends 0. I was thinking of selling this setup locally for 800 dollars, than buying the w7's for 6, selling one of them and than make a ported box for the other and use it as an daily driver. The mtx 1501d is having a big effect on my elect system... I still have the stock alt. Anyone else? thx for the opinions so far btw
edit: and yes im looking for SQL

How will his 15" XXX have more cone area than two 10" w7's??

However, if you have a single sub that's displacing more air for a given level of excursion (versus a pair of 10s), that means more output with less distortion.
Math pie or 3.14 x's radius then squared
10W7 roughly 5 x 5= 25 x's 3.14= 78.5 x's 2 = 157 cubic inches for the 10W7's
vs
XXX 15 7.5 x 7.5 = 56.25 x's 3.14(pie) = 176.6 for the 15 inch XXX
then multiply that by the xmax and you have an idea of which will move more air.
