to find the cone area of 3 12" square subs
x=(12*12) 3
x=(144) 3
x=432 sq"
to find the area of 2 15" square subs
y=(15*15) 2
y=(225) 2
y= 450 sq"
x<y assumeing both subs have the same x max but the difference will only be noticalbe on a mic and not by your ears
there are other things to talk into account the box and what the final resistance of the 3 subs will be.
also 2 subs is almost always cheaper than 3

oh and P.S. the 12s will also work better in a Jimmy because with 4 15s you can't design a box that will be as good in a jimmy as a box that you could build for 3 12s. Jimmys (and most SUVs) like boxes with the woofers pointing up and the ports sticking out the outside of the box and pointing backwards. T/S parameters mean nothign, box programs will tell you that the bigger the box the better which is also not true at all. In reality those 12s will be loudest in around 1.75 cubic feet each with 2 4" aeroports per woofer...its a very commonly used box in SPL and is very loud. Bigger boxes are NOT better. In fact you get quite a bit louder by making the box smaller. I assume that your Jimmy is like many GM vehicles which have 40" between the wheel wells. This works well with 3 12s as you can line them all up in a straight line. This is better than what you can do with a 15 because with 4 15s your only options are to have them two across and two rows or to do a wall...if you are gonna do a wall then 15s would be just fine but if you plan to do a standard box the 15s closest to the front will not give much to the design because of the extremely poor acoustics that a woofer in that location in that vehicle will give. you really want the woofers about a two feet from the back or so (not the 4-5 feet that the second two 15s would be which would kill their output acoustically speaking)...further than that will give you serious SPL losses in such a box. You really need to talk to someone who knows what they are doing and not most of the people on here (with the exception of Arok who I beleive does know a whole lot)
