Powering nine home speakers

Hi. I have a large open living room and want to increase the wattage I have running my speakers. I currently have an Onkyo 7-channel amp and took the front left and right outs and have them going to an OSD Audio ATM7 7-zone speaker selector. However the Onkyo amp is not powerful enough to drive all 9 speakers strong enough. It sounds very weak. 

The only device I want to connect is a sonos connect that I have. Currently I connect the optical out of that to the Onkyo amp. Should I introduce a second amp? How exactly would I connect them? Would I run the sonos connect into one amp and take the preamp outs to the other amp? Can you have a standard front left and right out AND a preamp out at the same time?

i only want/need stereo sound not surround. 

Thanks!

Great idea! How’d I miss that? ;)

What is the point of the switch in this case? I’ll always want all 9 playing at the same time so is a switch necessary?

I thought you have a HT setup using the onkyo in a dedicated theater room and want to switch the music to your living room?

No they’re two dedicated amps. Would I be better putting 5 speakers on one amp and four on the other to more evenly equalize the power?

Best to have each speaker with its dedicated amplification so you can adjust each channel level for evenly distribution.
