Can I wire 3 speakers to a Wiim Amp? More questions

[Dragonballz]

Hi

Can I wire 3 speakers to the Wiim Amp? I am prewired for 2 ceiling speakers in Room A and 1 ceiling speaker in Room B. I prefer Room A to have a separate Left and Right channel but it is not neccesary. Everything can be mono if needed.

Would I be able to “shut off” room B’s speaker by fading the audio to one channel?

I am not an audiophile but I can appreciate good sound quality. I will just be using these speakers for music, maybe even just low volume background music.

I listen to mostly American rap and pop. Any recs for ceiling speakers?

Thanks
