adding speakers

You can add a second Sonos Amp to power the in-ceiling speakers and either use them as surrounds with the first Amp or just group the two together in the Sonos app.

Thanks for the fast response!  I should have mentioned I was hoping to not spend $600 to add speakers that only cost $100.

An impedance matching speaker controller/switch would likely do the job.

Thanks for the idea.  I’ve never used a switch before.  Would I wire all 6 of the non-Sonos speakers to the switch and then connect the switch to the Amp or do I just connect the 2 additional speakers to the switch and leave the other 4 connected to the Amp?  I appreciate your help!

Amp to switch, switch to speakers.

That way the switch can manage the connections and impedance.

So the AMP has 2 sets of speaker terminals.  The Switch has 2 sets of terminals labelled “AMP” and speaker connects for 4 sets.  I have 3 sets of speakers.  I connect all three to the switch and then run speaker wire to one of the AMP speaker terminals?  I apologize.  I’m new at this.  The ARC was a gift.  I’m thankful, but I had a Sony receiver with speakers attached.  This is a whole different world.

Sonos Amp to switch amp connections. Pay attention to the + & - as well as right and left.

Each speaker should go to the output of the switch, again watching he + & - as well as right and left.

So four conductors from the Amp to switch.

Four conductors from the switch to each pair of speakers.

You will have one set of speaker terminals left open.

The switch should have at least a minimal manual with a couple wiring diagrams to help out.

How are you using the SONOS ARC? Is this intended to be a surround system?

Stanley, thank you so much.  Buzz, I am not attempting surround.  With my system, we are mostly listening to music or watching regular TV, Hulu, or Netflix.  So, just stereo.  I just have some speakers in the ceiling that aren’t doing anything and it seems like a shame.

Something like this perhaps…
