Wondering if anyone can help get me pointed in the right direction. We recently moved into a home and there are built-in speakers in several places. The previous owners had a receiver connected and left this behind: . https://imgur.com/a/UwqGD4gI would like to attach a Bluetooth receiver and use the built-in speakers. How do I figure out what I need to connect in this mess and which wires go where? |

| You can take a battery, AA or 9 volt and connect it to two wires at a time, you'll be able to tell, static, when you're on the speaker wires. However, you won't be able to tell the phase of the speakers. Which wire is positive / negative, you'll probably have to take the speakers out and look to see what wire is connected to what terminal. |
