DESC: KICKER amplifiers have always ruled the winner's circle at car audio competitions because they combine remarkably advanced design with the highest-grade electronic components for the ultimate combination of sound quality and brute power. Beneath the exciting new ZX series exterior lies internals that have been designed from the ground up to deliver tight, clean power. An unregulated Class A/B power supply allows the amplifier to really pour on the power in 2-ohm operation. All this power is at your command with variable crossovers, high- and low-level inputs, and variable bass boost. Fast-acting protection circuitry guards against short-circuits, over-voltage, overheating, or wiring mishaps. Gold-plated RCA input and output connectors insure maximum conductivity and resistance to corrosion. High 22kOhm input impedance lets you link multiple amplifiers in a single signal chain without having to use signal-robbing splitters.
