Hi I have a Sonos Beam and 2 play ones as surrounds. I also have a connect amp and would like to use it with a third party powered sub. Would this work as a 5.1 setup and would the sub volume work with the beam as its a powered sub and it has its own volume. I have a red and white rca line input, would I need a 1-Male from the connect app a to 2-Male RCA Audio Cable.
Thank you.
