Compare Kicker ZX850.2 Car Amp to Kicker ZX450.2 Car Amp

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. Custom-tooled remote and speaker screw terminals are also gold-plated, while oversized power and ground terminals allow for large gauge wire connections. Dialing up just the right amount of bass is at your fingertips with the remote KickBass variable bass boost. KICKER even ships every amp with its own birth certificate – KICKER's guarantee to you that it meets their high standards for power and performance. Less
