Hi there, moved into a new build that has 4 ceiling speakers in an open area and 2 outdoor speakers. All I have is 6 wires in the closet. I read up on home audio but I am so confused on Ohms, watts and Imp. I have no info on these speakers and just wondering if I need an amp and speaker selector, or just a receiver, or receiver / speaker selector...any advise would help. I only want it for music. Thanks
