I have a customer that has a small theater room with existing in-ceiling speakers. He wants to convert to Sonos for ease of use. Can I use a Beam at the TV and then wire an AMP to the front left and right and a second AMP to the surrounds? I can see that you can use two amps in a four-channel surround setup but I cannot find any confirmation on adding a Beam or ARC for a center channel.

Thank you for any help you can give.
