Hi everyone! I have a question, i currently have a Creative I-Trigue 2.1 setup hooked up to my laptop, and I want to buy 4 Bose Cube speakers. the speakers dont come with subwoofer or amplifier or anything, just the four cube speakers. Can I hook them up to the subwoofer of my current Creative system, thus replace my 2 current speakers with the 4 bose cube speakers? and how do I do that? Thanks for any suggestions!!!
