Surround Sound out of Stereo System

[Calibretto]

I have an RCA Stereo System with two speakers but it would be kind of cool to add two more and implement surround sound but how would I do that?

do you have any pic's?

nope, the speakers connect through the red and black stereo wire.

then, just connect more speakers w/ r&b wire

but the same sound will come out of all three speakers thus not implementing surround sound.
