Hey all, just bought a house and it's is pre wired for surround sound. There are 6 speakers locations, 3 in the front and 3 in the back of the living room. I'm a noob to all things like surround sound. What kind of system do the wires suggest I should get? 6.1? 5.1? I don't want to leave any wires exposed or just cover them up. I want to use what's provided since it seems pretty convenient. Any suggestions on system would be great. Price point would be entry to middle tier, not looking for high end at the moment.
