3 audio outputs or inputs? on my PC woofer

[hiyall]

what are these audio ports for? they are yellow green and blue. the yellow is currently in use for my left speaker and my right speaker is in via VGA cable and there is a blue and green port left over unused. i figure it would be something to do like surround sound but when i plug my left speaker into those other blue and green ports, no sound. how would i go about using these ports?

take a pic and post it

or what types of connectors are you using?
most pcs use headphone jacks or toslink/rca for autio out
green/blue/orange/black for analog surround 2.0-2.1-5.1-7.1
pink is mic
gray is stereo input

orange rca or toslink ia digital audio (spdif)

yellow rca is a composite video jack

my junky computer only has one audio output unfortunatly. i shouldve built my own. but i see now what the ports are. i kind of just guess what they are cause i have it mounted under my desk so i can feel everything so its like im in the action but the ports are actually red and white that says aux input. so how would i use those? like for hooking up other stuff like game consoles? http://www.amazon.com/dp/B002FU5QM0/ref=psdc_172471_t3_B002HWRZ2K

ok, the db9 is not a vga, that a custom jack for the right speaker, it has volume/power/aux/headphone controls on it
the left is yellow just for amplified sound

the red/white are its stereo input

on the right speaker is its aux in put and headphone jack

to connect it to a pc, use a headphone to rca cable

to the green audio out on the pc to red/white on the speaker set

That speaker set already comes with 1x RCA(red/white) Male to 3.5mm Stereo Male Cable. You don't need to buy anything extra, unless u need an extension cable perhaps.
