I have a wall TV in a bedroom to which is connected a Tuner Amplifier (Yamaha) via HDMI. The Tuner Amplifier powers two front and 4 ceiling speakers at the back of the room (2 Left and 2 Right pairs). I also have an Apple TV and a Blue Ray player attached to the amplifier to Channel music and Media through the amplifier. I also have Sonos Play Base in my den on another floor connected to a TV and the house router. Ethernet is available via the same router in the bedroom and currently provides the internet connection to the Apple TV via an ethernet switch. I'm planning on purchasing a Sonos Play Bar for the bedroom. How should I connect the Ceiling Wired speakers to create surround sound? I do not mind eliminating my Yamaha Amplifier if the system becomes user friendly.
