hey, I have a question about resistances (ohms and the such)

I have a Behringer EP1500 poweramp which puts out 2x700watts into 2Ohms, and 1400 into 4 Ohms.

I want to connect this to my BA410 (4Ohms) and BA115 (8Ohms) but dont know how best to do it because of all the different resistnaces.

Could anyone help?
