How do i hook up my jbl creature speakers to my samsung 32" lcd tv? it only has 1 output cord.?

Speakers need power unless they have it built in -they would have a power cord if they did this. Most tvs don't power external speakers. You'll need a receiver for that. They cost anywhere from $200 on up. Basically you'll plug the tv sound into the receiver and then it plays audio out of the speaker.
