Power Acoustik RZ4‑1200D Razor Series – 4-Channel Compact Class D Amplifier, Built for Tight Spaces and Clean Sound
The Power Acoustik RZ4‑1200D delivers full-range signal performance in a footprint designed to fit tight installs without compromising output. As part of the Razor Series, this Class D 4-channel amplifier offers high-efficiency power delivery and intelligent signal sensing—making it an ideal solution for modern factory integrations and stealth builds.
Compact Chassis. Full-System Coverage.
Rated at 1200 watts peak and 600 watts total RMS, the RZ4‑1200D supports a range of system layouts:
- 100W x 4 @ 4Ω – for full-range speakers
- 150W x 4 @ 2Ω – for component systems or higher-load applications
- 300W x 2 bridged @ 4Ω – for small subwoofers or midbass drivers
Whether you're wiring door speakers or building a compact 4-way system, this amp brings the muscle with minimal draw and heat.
Built to Connect with Simplicity
Designed for seamless integration, the RZ4‑1200D features high-level speaker inputs with signal-sensing auto turn-on, eliminating the need for a separate remote wire when connected to OEM head units. Low-level RCA inputs (0.25V–6V) support clean signal paths from aftermarket sources.
Switchable crossover modes allow you to tailor your output with fixed high-pass/low-pass filters at 80Hz, while short-circuit, thermal, and overload protection circuits maintain system reliability under stress.
