I've had 4 built-in speakers in my room for 6 years and I've finally decided to take the initiative to figure out how to hook them up so I can hook up my music to it! The pictures (hopefully they show up!) show the wires in my wall and the ends of the wires, and that they have writing on them which I've taken to mean "right rear, left rear, right front, left front". BUT, I'm a total noob and I have no idea even where to start with this... Help??
