I'm trying to understand more about audio, but I'm confused about one point. I've heard almost all music is recorded in stereo sound, which is meant to be listened to on two speakers (or a pair of headphones). So what happens when you play stereo music through more than two speakers, such as in a car (which some have 10 speakers), or if you listen to music on a surround sound home theatre system. Is the stereo signal simply split up evenly into the speakers? So if you have 6 speakers, 3 will have one side and 3 will have the other. Or do stereos and amplifiers do more advanced things in playing stereo music through multiple speakers. I do realize movies are different and have sound encoded specifically for surround sound on multiple speakers. I'm only talking about pure music.
