Hi, and thank you for your question! The Amp is designed to power existing speakers you already have. So your Denon speakers for example. It really depends on what set up you're looking to do with these speakers. If you're looking for surround sound. You could plug the Amp into your Tv using the ARC port and use x2 Ones as rears. Then use the other two ones in other rooms! If you're looking to use the them all in surround sound then, no. This article on our support site should help keeping in mind that Amp, Beam, or Arc can be used as front on our home theater systems.

Hi, and thank you very much for reaching out. The Boost plugs into your router and it needs a power outlet. If you're setting up Sonos for the first time we'll walk you through set up on the Sonos app. But it's mostly just a button press. If you already have Sonos, the setup is the same. However you may need to tell your speakers to work off of Boost. Sometimes this is as easy as unplugging your products and plugging back in.( https://support.sonos.com/s/article/3636?language=en_US) However sometimes it does require extra steps. If it requires support, please don't hesitate to reach out to us at sonos.com/support.

Hi, and thanks for reaching out. The Sonos Five is not designed to be used outdoors. If you're looking for a permanent outdoor solution, we recommend a pair of outdoor speaker powered by the Sonos Amp, or the Move for a portable solution.

Hello, and great question! Yes, you can do that. Doesn't matter which one is which surround. No need to have voice mics in both speakers if they're in the same room, so we designed the One and One SL to work together as rears, and as a stereo pair, too!
