The JBL GTi Balanced Current Servo amplifier delivers pure, clean power with the soul of JBL pro gear. The A6000GTi features a high-efficiency switching power supply that draws far less current from your vehicle's electrical system. JBL's new Balanced Current Servo circuitry was designed in conjunction with Crown (the professional amplifier folks) and can push an astounding 6000 watts RMS into anything from a 4-ohm to a 1-ohm load. Unlike typical monoblock bass amplifiers, the GTi Balanced Current Servo amplifier actually has two channels that are bridged together in either a series or parallel configuration for maximum flexibility and power output. Features include variable low-pass crossover with selectable slope, and variable Dynamic Bass Optimization (DBO) subsonic filter. Drive your subwoofers with pure Balanced Current Servo power and you?ll know why JBL is the official brand of live music. Minimize
