Sorry, what is a “Sonos1 Amp”? Is it a CONNECT:AMP running S1? Or a Sonos Amp?

What output from your Sonos device are you attempting to use?

Does your BOSE have an analog input, or is it some other kind of input? Any chance of posting a link to the manual for this device? Which input are you plugging the Sonos device in to?

Sorry, that is correct, it is a CONNECT:AMP, the white one that I added to my Sonos 1 system. 

Yes, BOSE has AUX Input here is a link to the manual.

I have a 5 disc base that is what I am connecting to.  Everything works on the Bose side. 

thanks for your help 

The Sonos Connect:amp does not have any suitable outputs to connect to anything other than speakers / subwoofer.

Very helpful, thank you!

Normally, you’d take a line level audio out and plug it in to the Aux In on the BOSE, but you don’t have one. So you’re going to be challenged.

The Sonos does have an analog line in, they’re labeled “Audio In” on the CONNECT:AMP. Some people would suggest that you take a speaker output, and use that, but the chances of blowing out the electronics in the BOSE are too high, for my tastes. You’d be better off getting a Sonos CONNECT, which does have an analog output, and connect that to the AUX In on your BOSE. 

Thanks, I will look into this 

@Airgetlam -- my mistake on the start, I have the CONNECT - no AMP on it. 

I wish I could attach a photo to show you as it does have the analog out (white and red)  

Ah, suddenly things become much better and easier :)

Connect the Analog output from the Sonos CONNECT to the Aux Input on the BOSE, and then you should just be able to “play” that output on your BOSE speakers. 

Thanks, I will double check my setup

If you have a Sonos Connect you can use the TOS Link to connect to your BOSE device. I have my Connect attached to my BOSE Soundbar 900 this way and it works great. Just have the impression that the Bass box is not working this way.
