Yup. Left out to one, right out to the other. A mono-block amp is just one, presumably bigger, amp in a box. One input; one amp; one output.

also what does it take to design a stereo amp to also be used as a monoblock amp? I know you have to use a jumper and connect the speaker wires up differently but that's about it.
A stereo amp can often be put into "bridging" mode, which is what I think you're talking about. I'm not fluent in this, but I just looked it up in the audio engineers handbook, and bridging mode is not a balanced differential drive scheme---on terminal remains at ground potential. SOmeone here may be able to give you a simplified, clear answer, but I'd bet if you google "bridging power amplifier topology" you'll find some explainations.

What I can tell you is that the B&O class-D power amp module is capable of balanced differential inputs and outputs with proper strapping configureation, and that will use it someday.
