I am having trouble with my subwoofer output. I am connected in the following way. I do not see amp settings in the Sonos app either. I also tried to connect the single RCA cable between amp and subwoofer with no success. I do get sound to the bookshelf speakers but no sub.
Turntable -to- connect AMP with RCA cables
Connect AMP -to- subwoofer input (wired)
Subwoofer -to- Output to small bookshelf speakers (wired)
Please help I am new to setup and may have it totally wrong.
Subwoofer is a Orb super eight
