I suspect this isn't feasible, but I have a connect:amp with a pair of polk outdoor speakers being driven off of it. They sound great. I also just added a 12" 300w sub that I previously owned into the Sonos system via the sub output on the Connect:AMP.



Thing is, it seems like the connect is only able to be a single output device, and there's no way to group the sub output as it's own item (like as part of a home theater).



Ideally, I'd like the outdoor speakers to be their own "room" and the sub to be part of the "living room" which also has a pair of Play:1's and soon a Beam soundbar. I'm not seeing anything in the various controller apps indicating this is feasible.



Is my best bet to just buy a Connect and use that to drive the subwoofer (still cheaper than buying a sonos Sub when using my existent SUB)? If so, that's annoying.



Also, I read on another post that if you have a sub connected to the Connect:AMP it does not send anything
The sub output on the Connect Amp is just split off the two main channels, there is no separate music input going to it.



If you buy a Connect to run your stand-alone sub woofer you may discover it has no sub output, that is available only on the Connect Amp. The third red connector on the Connect is a coax digital output, not a Sub. See the zoomed photo here:

Folks report problems here, not sure wich topic you are thinking of. Working properly the Connect Amp will provide a line level output to your external non-Sonos sub woofer.



Why not just buy a Sonos Sub and pair it with your other Sonos speakers and avoid all the problems?
