Hifonics Zeus ZXi Series is an incredible mixture of sound quality, flexibility, and endless raw power. Every Zeus ZXi amplifier sports a large blue illuminated Hifonics logo and an array of blue LED light pumps streaming light down the heat sink to show, you only own the best! Today’s sound systems focused on sound quality usually have a Hifonics Zeus amplifier at its nerve center. You deserve the best possible soundstage in your vehicle. Let Zeus ZXi Series deliver it to you. The all-new Zeus ZXi amplifiers feature our latest Ultra-Fi™ MOSFET output devices. Ultra-Fi™ outputs boost the ZXi amplifier’s performance by lowering THD and Noise, and increasing transient response with faster slew rates. The ZXi differential inputs combat electrical noises right at front of the amp’s input RCA’s. As a result, this high-speed Ultra-Fi™ circuitry delivers the cleanest and widest bandwidth possible in a mobile amplifier system.
