We are adding an addition to our home and I would like to utilize the Arc soundbar, two in ceiling speakers, and sub for TV watching. I will also be purchasing an Amp to control this. 
 

1.) Does this setup make sense and can I run everything from that amp and the sound will sync with TV?

I am also adding two outdoor speakers to the patio. 
 

2.) Can I run the outdoor speakers to the same amp and use as a separate zone? Is whatever I am playing in the new room going to play on the patio? How would I go about making them separate zones? Two amps? A port?

I feel like I am getting conflicting information online (shocking I know). This feels like it should be more straight forward. Appreciate the help Sonos peeps!
