Welcome to Techspot !
I have the same set of speakers .They sound pretty good. You didn't put much detail in your spec sheet in your profile so I'll pretend you have a sound card .At the back of the sub woofer there is a red socket that says 'spkr out'.Use the fatter wire with the red ends.Plug it there and into the satilite speaker with the control knobs on it.Plug the cream colored wire from satilite to satilite
In the green socket '1' under input ,plug the smaller green wire with green ends , there and to the sound crd 'speakr output socket" ( this should also be green)
There are one large knob( volume ,turn this conter clwise to reduce volume you can readjust later) and three small buttons on the top of one satilite speaker The top button pushes on/off ,push the other to adjust bass /treble
Plug in the power and test your sound levels
Enjoy
