So to top of my new Alienware laptop i decided to buy logitech 5.1 surround sound speakers. The package came with 5 speakers and a subwoofer, it all looks very nice but i can only plug the cables into my headphone jack. There are three cables, 1 for the front speakers, 1 for the back ones, and 1 for the center speaker, with one port i have to choose one and not use all of them, so i only have two speakers! Does anyone know what kind of adapter i need to make one port into three? Can i buy them at best buy or radioshack? Thanks very much.
