If all 3 pairs were connected to the same Amp, then there is no way to control volume separately (unless you have hardwired in-wall volume controls).  A single Amp is a single source, with a single volume control. 

Always take a picture of your working setup before you mess with it, too late now but for others or next time keep it in mind.

You want to connect each pair of wires coming from each cable to the right and left channels of the Amp.

Hopefully the installer got it done correctly and you can hook all Red to the + and all black to the - terminals. If the low frequency response is weak switch one cable’s pair to the opposite terminals.

Please dumb it down for me if you can. On the porch speaker cable I have a green, red, white and black. Which colors go together?
 

And in the great room, I have two cables with a red and black wire in each one.

Hi @Oceanwoods, Stanley’s advice is spot on. I might break it down into smaller steps:

1. Connect only GR Left and GR Right, confirm those speakers work, disconnect
2. Connect only Porch, confirm those speakers work
3. Re-connect GR Left and GR Right, confirm all speakers work

1. Works. 
    

2.  What colors go together ?

   

    

All speakers work. Music comes out of each one. My question is what wires get twisted to what wires so that I can control the volume in each of the two rooms?  Before the app upgrade, the app showed me two rooms. A porch and a great room. I could play music on the porch and not have it play in the great room or play both at the same time but at different volume levels. I am trying to get back to that set up and obviously I don’t know what I’m doing. Thx for help. 

I’m beginning to think if AirPlay was used to allow me to control the two rooms separately

No, one Amp means one source, Airplay doesn’t magically separate the rooms on the Amp.

Ok. Still need a wiring diagram. 

You’ve already got it working - you said music comes out of each speaker.  
 

If you have only one amp, that is one volume control for all speakers connected to that amp.  You cannot have independent control of the speakers connected to one amp.  You need multiple amps for independent control.  
 

I’m curious — you said you disconnected everything for the recent uodate — what do you mean by that as the no update  requires you to disconnect any speakers? 

I called Sonos and waited to 80 or so minutes until troubleshooting tech picked up. He had me try a number of things which led to removing wires as they were connected and start over. Call later failed and didn’t have time to wait in que for another tech. But before all of this I had this installed my a local AV company and I could control the volume in each zone from my iPhone. I could have the volume up on the porch and low in the family room. I’m going to make an appointment with AV company at this point. Thank you. 

Gentlemen, I have an idea: the Sonos Amp was in Dual Mono mode, and said mode is not yet supported in the new app.

I think Dual Mono mode might separate the Left and Right sides of an Amp (or Port) to appear as two rooms in the app. I cannot test my theory as I’m on the new app.

The wiring would have been (red-to-red, black-to-black) ...

• Amp RIGHT = GR Right and GR Left, wired in parallel
• Amp LEFT = Porch

@Oceanwoods Please don’t re-wire anything, yet

@Stanley_4 @jgatie @Andrew-s Chime in if you have an insights

Aha, confirmed the second half of my theory. Dual Mono mode is not yet implemented in the new app.

All makes great sense now. Thank you all.
