dumb question of what would be best

[Mathman 0]

I hate to ask this, but I have hit a crossroad. I am looking for some real good output and have around 2k watts of power to play with. I have about 3 to 4 cubic feet of room to play with in the trunk of my car. What would probably work best, 1 15" BL or 2 10" BL's. I thought the 2 10's due to sheer cone area, but any other input would be cool. I am fearful I will not have enough room for a BTL, so that is why that is not in the running.

I'm not entirely sure that one BL will take 2kw. It might, but I haven't read up on it.
