M-Audio BX5a Reference Monitors to PS3 help

So I just bought some monitors cause they were cheap and I needed them for my music setup, but I wanna try them with my PS3. They have XLR or TRS inputs. I'm wondering if there is an adapter for maybe RCA to TRS or fiber optic or maybe fiber optic into my Samsung reciever and use the Component/RCA on that? I clearly am a bit confused on either how to do this or which route to take.

Go TRS to RCA.

Do you have a Radio Shack near you? They can set you up with what you need.
