I just got a phat stereo system that i want to use for my computer speakers. On the back of the stereo, we have two inputs (red and white) that are just like the ones that you plug your xbox cable into. I have a sound blaster Live digital 5.1 sound card. are there any cables that can use the stereo as speakers for my computer? my dollar tree speakers just don't cut it for my new computer. any help is appreciated.thanks in advance
