The mustang trunk can't be smaller than the little trunk in my camaro. I'm not talking about the hatch part, but rather the trunk (hole) in the back of the camaro. I fitted in TWO 15" Fusion subs with custom boxes. one box for each sub. If i could fit two 15" subs i'm sure you should be able to find a way to fit them too. It does sacrifice a bit of bass though if earth shattering bass is what you're looking for. Plus, i'm not sure but i think loud bass will be very hard to achieve in a convertible coz all the bass is not enclosed and escaped through the soft-top (sorry, don't know how to put it any better than that). If you want a balanced system without needing to tnue the bass all the time to get it perfect i'd go with the 10's. I just like havin 15's coz sometimes i want balance and other times i just feel like car shattering bass. Guess it depends on how much bass you like.
