Hello everyone. Glad I found you guys. So I just bought a house and the house is pre wired for surround sound in the family room. Where the cable tv input is there was a plastic cover that I uncovered. In there was a wrapped wires.... 3 blue bundles(with 4 wires in each of them) and 2 coaxial cables. I believe my house is a 5.1 . There appears to be 3 pre wired holes on the top front and two in the rear of the family room. How does this correspond to the wires that are shown here.
