I recently bought a new house and it has speakers in the ceiling all through the house. I can't find a outlet where the speakers wires would come through. I went into the attic and the speakers are still there but I can't get to them as they are in the corners where the ceiling drops and there's no boards to stand on by them. I'd like to find a way to hook them up or have some advice. I've never dealt to with a ceiling system. Do they normally have a central spot they all link up to?
