^^^ in playing loud music, when loud bass notes hit, the car's battery cannot discharge at a rate fast enough to keep up with the current draw from the power amplifiers...however capacitors can quickly store charge and can discharge at a much faster rate, so your music system doesn't suffer from starvation and your lights etc don't dip as much (or not at all if your current supply is adequate)

not quite....because mankind as yet to create a speaker that plays all frequencies in the audio spectrum with precise clarity, we have no other choice but to have separate speakers for the different ranges; sub-woofers for those earth-shaking lows, woofers for our mid-bass and punchiness, mid-range drivers for well, midrange, and tweeters for brightness
a crossover separates, the audio signal into these ranges (some thresholds can be set by the user) and then the sound can be manipulated either directly to a driver or through an amplifier network, depending on the application and the type of crossover unit |
