Hey all, my question is how do I connect my mobo's sound output to my stereo's input? The mobo has (4) 3.5mm outputs(left, right, sub, side speaker), the stereo has (6) rca inputs(front left, front right, rear left, rear right, sub, center). Although the stereo is old, it puts out good sound. Besides that, using it means I don't have to buy a seriously expensive computer speaker system.
