A:Answer Hi, thank you for your question. The Sonos Amp can accommodate four speakers connected wired in parallel, as long as the speakers are 8 ohm. If you can ensure that these speakers are 8 ohm, and you can wire them in parallel, you should be fine. If the speakers are 4 ohm or 6 ohm, you would need to purchase a second Sonos Amp to accommodate all four speakers.
