Sonos Amp wiring question

I am putting a couple of Klipsch AWR-650-SM speakers around my pool, and wiring them to a Sonos AMP (the new one). I notice the wiring coming out of the speaker is 4 conductor wire, and the Sonos AMP has 2 banana plugs. The wire distance to one speaker is about 120ft, and the other speaker is about 150ft. I plan to purchase direct burial speaker wire.

Here are my questions:
Is 12AWG wiring sufficient or should I go with 10AWG wire?
Do I need 4 conductor wire? Or can I do 2 conductor wire and wire the 2 positives from the speaker to the positive on the wire run? and then do the same for the negative wires.

120'-150' is a bit long for speaker wire runs that aren't using a 70V system.

You need four conductor cable because those speakers have dual voice coils, so you need to wire them according to the diagrams that come with the equipment. If you wire them by connecting the two pairs parallel, the Sonos will supposedly handle it (should be OK since the long cable run will add resistance) but if the speakers are far apart, the sound from the opposite channel will be hard to hear when you're close to one of them, so each speaker is connected to both channels so your location won't matter. This is called 'Distributed Audio' and stereo separation isn't important- getting all of the sound out there is the goal.

The speakers have Red, Black, White and Green, right? The conventional color scheme is:

Red= Right +
Black= Right -
White= Left +
Green= Left -

Yeah, I don't want/need/care about stereo. same sound out of both speakers. getting as much power to them to get the most sound is probably most important since they are outside. sounds like you are recommending the 4 conductor cable.

No, you NEED 4 conductor wire if your system is running in stereo mode and don't want the sound from the music to bounce from channel to channel (listen to old Beatles songs for good examples of this). The one way around that which would give you the most power and make sending both channels to each speaker is setting the AMP to Mono. Look in the menu for Advanced settings, Audio and check the box for Mono.
