Hello, I recently bought a house which has a single speaker wire located in the ceiling of five different rooms. Each wire comes to one location for a source hook up. My question is, How can I hook up a single stereo receiver to the speakers to play background music? The rooms only have one wire for one speaker. I don't mind if it will only be mono or that the same music is in all the rooms but what equipment would I need to accomplish this. I would appreciate details on this. Thanks!
