This again does not look any different then a normal stereo amplifier setup(Amp takes the input signal and makes it big enough to drive the speakers the speakers then selves are powered off this amplified signal) except that your amp is contained within one speaker. The signal coming from that plug is amplified(powered if you will, it is much stronger then the one that entered the system from the computer) and is at a higher voltage audio signal that the speaker will playback without need for any other power source.
