Hi Jamie, This would not work. The only way to accomplish this would be with a 3rd party device that converts stereo sound to mono, a Monogizer:

I do not believe the Monogizer will work since it will common ground the amplifier in the Connect:Amp. A best solution would be to use a single stereo speaker such as the Sonance VP65R SST [ ] which has a dual voice coil woofer and a pair of tweeters.

Hi Steve, Your solution of using a single stereo speaker will work, though using a Monogizer will work from a ZP120 as well. From the ZP120, you will run 4 cables (2+ 2-) to the Monogizer then 2 cables, positive/negative, to the single speaker.
I have not tried the MonoGizer, but I did buy the MonoMixer, also from AudioPlex, to convert stereo input to mono output. Unfortunately, the Monomixer requires an amp with common (grounded) minus (black) speaker terminals - this does NOT include the Sonos Connect:AMP. There is a solution, which requires two MonoMixers to defeat the absence of a common grounded (-) on digital amps. I have reached out to AudioPlex to determine if the MonoGizer has the same limitation.
