Hello, this may not be a true Home Theater question. My home had a NuTone intercom system what’s remaining are 3 round, in-ceiling speakers (one in each bedroom, with each speaker is a volume control on the wall. All the wiring all come together in one location (kitchen Pantry). Can I hook the speakers up to something like a Wi-Fi/Bluetooth amplifier so that I can play music in the room from my phone? If there is such a thing, any recommendations?
