A:Answer Unfortunately, I would not use these speakers with your Sonos Amp. The amp outputs at 8 ohms, and these speakers are rated at 6 ohms resistance. That low resistance will cause a higher power draw than the amp is rated for and it will either over heat or shut down due to thermal overload. In general, you want to get a speaker with either the same (ideal) or slightly higher ohm rating to save your amp. Hope that helps.
