I have a friend who loves to sing and is adding a room to his house. The room is the size of a two car garage. He really likes to sing. He preforms with a few groups around here. He wants a clear, deep sound. He asked me to set something up before the drywall goes up. Should I just run speaker wires in the walls? Do you think surround sound is neccesary for listening to music? You are supposed to hear music from the front stage, like if they were right infront of you correct. Would two speakers be good enough or should I put enough wires for four front speakers?
