How can I connect a speaker wire-out to composite-in?

To clarify, I do not need a receiver. I have a 5.1 system connected to a receiver currently. I have the 4 surround speakers connected, but I want to use the TVs built-in speakers for the fifth, center speaker. The problem is that I do not know how to connect the speaker wire coming out of the receiver into the TV. It only has composite-in ports. Also, I do not want to do composite to composite from the receiver, because then all sound and not just the center speaker sound comes out of the TV. Thanks

You would have to take the TV’s shell off, soldier wires to each of the speakers drill a hole in the casing and attach an external RCA jack in the casing, for each speaker, attach the wring for each speaker to the RCA jack; reassemble the TV and plug the center channel output from the receiver into the RCA jacks you have just installed using RCA cable.
