so ive plugged the right, left, bass, and center in but the front right has 3 jacks coming out of it, i only have 2 jack ports on my imac!!! what do i do???? ( green, orange-ish, black are the 3 colours of the jacks )
I believe your iMac only has one audio out port, the other is a audio in port (microphone). See this thread for more info on what you've got and what you need to make it work:

I don't have any first hand experience with this, but I've read about it. Okay, this is a very basic explanation to use a 5.1 speaker system with a Mac you have to use Digital Optical Out (called TOSLink by Sony). This requires a Digital Optical cable, they're different from analog audio cables. The Digital Optical cable connects from the Mac to a 5.1 device, like a home theater receiver, etc. and then your speakers are connected to that device. The 5.1 device takes the digital signal and breaks it down into the individual channels and converts it to analog to go to the different speakers. The last message in that thread has a link to an external sound card can also be used for this purpose. As I understand it without a Digital Optical cable and a 5.1 device your speakers are not usable as 5.1 speakers (see edit below) with your iMac.
Edit:
Okay I just looked at Logitech's web site and you can download the manual here:
2-channel sound card: Connect the green plug from the audio input cable to the line out jack on your sound card. Do not use the black or orange plugs. With a 2-channel sound card you will not hear sound from the rear speakers.
