Your 500W sound system doesn't draw that continuously. My wild guess is that it averages 120W, which is like running an extra pair of high-beams. Double that number (due to inefficiency in converting mechanical energy into electrical) and divide by 746 (electrical equivalent of 1hp), and you get 0.32hp extra load on the engine.
