I have my Computer hooked up Mini->RCA into the Game/TV RCA Inputs of my Onkyo 605. I have my X-MTM Left and Right hooked into the Left and Right channels with 12 gauge speaker wire. These work fine. The Subwoofer is hooked into the Pre-Out Subwoofer port with a Philips Digital audio coaxial cable (
Amazon.com: Digital Coax Audio Cable: Electronics).
I have not tested this with my Playstation 3, my other source.
