Trying to use z-5500 with TV

[NuclearFallout]

I got a question. I bought the z-5500 speakers a few months ago and they sound great for my ps2 and DVD player. I have the DVD player hooked into the optical in on the breakout box. My TV is an old Sharp that only has Audio IN and Video IN RCA jacks as well as the standard coax jack in the back. Is there any way to output sound from my regular TV signal to the z-5500s?

Thanks

If you have a VCR or receiver with audio outputs you can use those.
