Bluetooth Speaker

I am setting up a surround system and am quickly learning that the surround and surround back speakers CANNOT be connected by cable.  My understanding of Bluetooth speakers is that they are good for sound options but there is little or no mention of using Bluetooth speakers in movies or TV.  Ideas on how to “connect” speakers to a home entertainment system without speaker wire would be much appreciated
I doubt if I can help but bluetooth requires a transmitter and a receiver. You have to tell us where they are located.  
If it is a system follow the instructions to pair and connect. They are all different.
If it's not a system, try a wing and a prayer.
