I’ve had one SONOS Amp running two 8 ohm speakers for years with no issue.

I just purchased a second Amp so I could run another pair of 8 ohm speakers to a different area of my back yard. I connected everything today, and the new amp will play for about 10 seconds then I will hear a loud pop. The amp then flashed white and either orange or red (hard for me to tell the difference).

I tried connecting my old Amp to the new speakers and it works fine. I connected the new Amp to the existing speakers and had the same pop.

I’ve tried different variations between the different sets of speakers and the new Amp keeps popping.

What else can I check? Is this new Amp bad?

Thanks -Ron

It sounds faulty to me …based on everything you’ve mentioned and the fact your other Amp is working okay with the same setup. It maybe best to reproduce the issue and then immediately submit a Sonos system diagnostic report from within the Sonos App, note it’s reference and then contact/chat with Sonos Support Staff via this LINK and see what the Staff can perhaps suggest to resolve the matter.


YEP. Got on with Support Chat, and they found a hardware fault. Replacement will be shipped.
