I have recently received a Bose 3-2-1 system from a relative who has moved out of the country. Problem is I don't know how to set it up! I've easily enough connected the box to the speakers and subwoofer but don't know how to connect it to the TV. There is no scart socket on the back of the box, just lots of the red, white and yellow inputs/outputs. What do I need here? Thanks, and excuse my newbieness.
