I have mine hooked up to a home theatre system, (basic receiver, speakers and a powered sub), all you need is the adaptor for a standard headphone jack to rca cable to work.
Spent about $200 total from local pawn shop for the Yamaha receiver and 200watt powered sub. Speakers I use are some bose that I got free from a friend. Nothing special, good bass. Great for games or movies since my computer is hooked up to my 40" flat screen.
