I don't see how you can because you can't just set the ohm load since it's dependent on the ohm load of the subs, and you don't have enough speakers to wires them in series/parallel.
What is the ohm load for each sub? 4ohms right?
Sounds like your amp can't handle anything under 2ohms. Is 4ohm the amp minimum load?
If the other channel isn't going to be used you could just add a terminal cup, or drill a hole in the back of the box for the other sub and seal it with liquid nails or something similar.
