with each speaker there's a +ve and GND so if you got a souldering iron and some headphone jacks you could probably solder the wires and plug them (the speakers) in. There might be an easier method or tool but that's the only way I know.
not the best pic but it should do: http://static.flickr.com/3147/2406438104_5a687610dd.jpg
Thank you,
But i would need 6 of the 1st cable,
And on my motherboard are only 4 outputs ( i think )!
Will it work! that i will take all the speakers to an electrician to connect the speakers wire with this cables!
You don't want to plug your speakers directly into the sound card of your PC. It does not have the power to drive the speakers. Plug your stereo in the PC instead - the stereo has a built in amplifier.
