I have a MSI integrated sound card, but could change it, with a Cyber Acoustic 5.1 silver pro 180 watt system with a 80 wat 10 inch subwoofer. I was wondering if i could hook up one more subwoofer to this. I was hoping i could take a 10 inch car subwoofer and mount it in the other corner of the room. I can get ahold of any wires or cards i need...please give me a step by step on how to convert the wiring connections so that it will work, and if possible maybe a good lower priced subwoofer and amp combo, thanks
