I have moved into a new house that has 2 outdoor in-cieling speakers (6 ohm) and 2 external speakers (8 ohm) are already in place and wired back to a central point. I am not sure what the last guy used to power but I would like to use the Sonos AMP.
Can I wire a 6 and 8 ohm speakers in parallel? Same total impedance on left and right?
