I have a couple of surround speakers that I would like to connect to my lcd tv. These speakers were from my old sony crt dolby prologic tv and they are wired positive and negative and have a small 2 pin adapter to connect to that sony tv which is incompatible with my new tv. My current tv has rca/phono output (L & R) and wondering if I can wire these speakers to RCA plugs?? Im thinking that the plugs will have to incorporate + and - terminals so I can just screw the wires in. Anyone done this before? Or does anyone know if the plugs Im looking for are available?
