There are four sets of wires coming out of one wall - how can I tell which wires are for the rear speakers?

Question

I am trying to connect my rear speakers to a Rocketfish wireless rear speaker system. The room was wired for surround sound, but I have my front speakers connected directly to my receiver. So, I just need to figure out which wires are for the rear speakers, so I can connect those wires to the Rocketfish receiver.

Answer 1

Get a 1.5 v battery
Connect the speaker wires to the + and - and you will hear a tone! The tone should point you on which speaker is connected to what wire. Make sure you connect the speakers to the battery for just long enough to hear that bip!! Disconnect after that.
