stereo wire to RCA jack

Now I want to hook up my Abit FP-IN9 nvidia 650i motherboard to my stereo speakers. My stereo speaker wires have two seperate wires each, and i want to somehow convert, or adapt it to an RCA jack. And i was wondering if anyone had any idea of how to do this.


Now my stereo wires pretty much look like those, except it's only two seperate wires per speaker.


Thanks in advance.

 

Scratch that, not RCA, a TRS connecter
