Power Acoustik RZ4-2000D 2000W Class D 4 Channel Amplifier , Black , 13.60in. x 6.30in. x 3.50in.

The Power Acoustik RZ4-2000D is a super-compact, high-efficiency 4-channel Class D amplifier from the Razor Nano series, delivering a legitimate 1000 watts RMS (2000 watts max) in a chassis small enough to mount almost anywhere — under seats, behind panels, or in motorcycle fairings. Perfect for powering a full front + rear speaker system or bridging two channels to drive a pair of moderate subwoofers. Features 2-ohm stereo / 4-ohm bridged stability, MOSFET power supply, military-grade SMT PCB, and a hybrid aluminum heatsink that keeps it cool even under heavy loads. Variable high/low-pass crossovers, 0–12 dB bass boost, and high-level inputs make it extremely versatile for both factory and aftermarket radio integrations.
