My Speakers are driving me crazy!!

Well, I haven't tried anything with my speakers yet, but just thinking about it is driving me crazy... I have 8-channel intergrated sound in my mother board. I have built-in speakers in my moniter and I have a Logitech mini sound system with one seperate sub-woofer. This is what I want to do:
I want to connect all my speakers together! :D

Can I do it without having to buy something new? All I want is sound coming out of all the speakers, I dont care if it's divided into different channels...
HELP ME!! PLEASE!!!!

You plug your logitech system in and then get a splitter and use it on your front channel and plug the front speakers for your logitech into one port and your monitor speakers into another and plug that into the computer. Problem solved.

Though, I wouldn't recommend using the monitor speakers if you have better ones, typically they aren't that great and will probably detract from your audio experience.

I see, so i DO have to buy something, well then I'll just hold off on connecting my moniter speakers then.... :p
