Using External Speakers

Okay, the speakers on the Macbook aren't quite good for watching movies on with your family. I hooked up my mac to the TV, but it only sends video, and my macbook speakers can't project that much. We have both a huge speaker system, and XtremeMac's Tango iPod speakers. Is there any way that I can connect it to either one of these, or the TV? Any help would be awesome!
