A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

    All About Discontinued Sound Processors for Factory Radios


    Most original factory stereos use preset equalization curves that are based off original (OEM) factory speakers. Processors in this category reshape the output of such equalization curves and give you the best possible sound when you upgrade to aftermarket amplifiers and speakers.
