Connecting existing amp to Sonos Port. Not working.

My house had existing Sonos in ceiling passive speakers. All connected to a Sonos Connect in the den. 
 

I replaced the Connect with a Sonos port and used an existing amp/receiver. Sonos speaker left/right connected to the amp, line in to the amp from the Port. When I play Pandora thru the Sonos 2 app I get no sound at all. 
 

I’m stumped. I was careful to mark left/right speaker cables hot & ground before connecting them to the amp. I did use crimp connectors to extend the length for connecting to the amp. 
 

Seemed pretty straight forward but I’ve got nothing. 
 

Thanks for your input/advice.

This got me thinking.  Since the speakers are passive, I should be able to hook up the amp without the Sonos Port. If it’s still not working then it’s the wiring.  Make sense?

 

Could be dueling volume controls.  Either set the volume on the Port to “Fixed” and use the volume on the receiver, or set the volume on the Port to “Variable” and crank the receiver up.

Hi.  Which input on the Amp does the Port connect to?  Is that input selected as the audio source on the amp?

It’s a small amp with only FM, Bluetooth, and Line In modes. Line in is the only input option (RCA connectors). 


Thanks.

You can check the speaker wiring using a flashlight cell. At the instant of connection there will be a “thump” if the wiring is complete and the speakers are working.

‘’Thank you, thank you thank you!

 

Fixed works!  Variable does not but I don’t care. 
 

Thanks for everyone’s responses.
