Since the amplifier has a built in crossover to remove the high frequencies the woofer cannot play from the signal, you get exactly what you need in the A100's - crisp, clean bass and nothing more. When connected to your system, the end result is seamless integration, both electrically and audibly, yielding sound quality your factory autosound system simply can't touch.
