I kbought my boys a Sony 5 piece Surround system for use on their TV. Tv has VCR and DVD within. All that came in the box is 5 speakers ..4 that look the same and 1 larger flatish looking one. How do I get these speakers to work on the TV so that they have surround sound when watching TV and Plyaing PS2? Help, I have no idea what I am doing, I just wanted them to have better sound! Thanks, Mom.
