Hello all I am new to the forum and I am new to home audio. I could not know less about it. Figured I would post here to see if anyone could help before I call someone In case this is easy. I just bought a house and it has speakers throughout but I don’t know how to work them. so far I have 2 units in the walls that do not turn on when you hit any buttons. Then I have 2 wires coming out of the wall, as well as these 2 hookups. Can anyone point me in the right direction? Thanks! jack
