Using Sonos Port with Bose SoundTouch 130?

Hi

The only non-Sonos speakers I have is a Bose SoundTouch 130 sound bar & Sub in my basement. I’m wondering if the Sonos Port will allow me to add the Bose system to my Sonos app. The Bose has a co-ax port, is it as simple as buying a port, running a line from the digital out into that port on my Bose then setting it up? 

Or am I way off and oversimplifying this whole thing? 

I’d like to avoid buying an ARC and Sub for the basement simply because we don’t use it that often. 

Thanks.
