My family just purchased a new Samsung 55 inch tv and i was trying to connect the external speakers i have in the wall to the TV. There are a total of 12 speaker wires. 5 speakers and 1 sub woofer. Before we bought the new TV, All 12 wires were connected from the wall to a Pioneer 5 DVD disk/ CD changer that is about 10 years old. When using the Pioneer 5 DVD disk/ CD changer we would get surround sound when watching movies and playing music but never for watching regular tv. My question is how do I connect the surround sound speakers to the new tv? Can i some how use the Pioneer to connect with the Samung so it would use the surround sound when watching regular tv? Or do i need to get a receiver? Explain slowly because i am new to this. Thanks!
