I have a powered subwoofer, will combining left and right channels with a cross conflict with it?

Probably not a good fit unless you are replacing the amp in that sub.

Can it handle a 12 inch sub 200watts?

It can drive the speaker, but how well will depend on the efficiency of the speaker and not just the size and watts it can handle.

Will this amp work on n bluetooth subs?

Probably not, bluetooth subs usually have their own built-in amp.

How does it connect to sub out on 5.1 receiver?

Treat it like a powered subwoofer and use the powered subwoofer out.
