Question about in house ceiling speakers

I am closing on this house tomorrow and am curious about the current setup.  Appears it's a sony STRDH710

I was able to turn it on and it only played in one room (the room with the TV ironically).  Since our TV will be in another room and that I have sonos, I simply just want to play music on all speakers in the house.  I don't care about any connections to a TV. 


Is it possible to just buy a bluetooth to White/Red cable adapter and then White/red splitter to all other speaker connections or is there a receiver that is Bluetooth eligible that can play to 10-14 speakers in the house?  




A receiver is wrong for this application you need a mutil channel amplifier or a load matching speaker selector
