History

Zapco was officially incorporated in 1974 with a mission to design and manufacture audio products of unsurpassed quality. In the 1980s, the company pioneered the use of optical isolators in car audio amplifiers, enabling integrated chassis designs that reduced noise. By 2004, Zapco amplifiers equipped approximately 35% of award-winning vehicles at IASCA world finals, establishing the brand as dominant in competition car audio. That same year, Zapco developed the first full-function car audio DSP (the DSP-6) and introduced a line of amplifiers with integrated DSP functionality. Since 2011, the company has continued experimenting with amplifier technologies to advance car audio performance closer to live sound reproduction.
