Power Acoustik RZ4-2000DSPB 4-Channel 2000-Watt DSP Amplifier

Delivering consistent 2,000 watts of Class D power across four channels, the Power Acoustik RZ4-2000DSPB is engineered for serious car audio configurations. Built for enthusiasts who require clarity and control, this amplifier combines full-range amplification with a built-in Digital Signal Processor (DSP) that offers detailed customization without the need for external processing gear.

The compact chassis (4.75” W x 11” L x 1.625” H) fits easily into tight installations without compromising output. Internally, military-grade SMT PCBs and IR™ audiophile-grade transistors ensure thermal stability and signal integrity across all driving conditions. A die-cast aluminum heatsink ensures effective heat dissipation, thereby preserving lifespan and performance.

The RZ4-2000DSPB supports precise tuning via SigmaStudio™ software, accessible through Bluetooth or USB. Compatible with Android, iOS, and Windows, this software enables full DSP control—from time alignment and crossover settings to a per-channel 10-band EQ with adjustable Q factors. You can adjust high-pass, low-pass, and band-pass filters with slopes ranging from 6 to 48 dB per octave and apply a time delay in 0.05 ms increments up to 20 ms.

For OEM integrations, the built-in high-level inputs with signal-sensing turn-on eliminate the need for a remote wire, making installation seamless even with factory head units. RCA low-level inputs (200mV–6V) and pass-through outputs allow flexibility when connecting subwoofer amps or expanding system design.

Performance is backed by stable operation down to 2 ohms in stereo or 4 ohms bridged, with comprehensive protection circuitry against thermal, short, and overload conditions. A bass boost circuit with a 12 dB gain and full crossover controls adds punch without distortion.

Whether you're configuring a front-stage upgrade or a full multi-channel system, the RZ4-2000DSPB provides scalable power, deep DSP control, and a platform that integrates cleanly with both modern and legacy vehicle audio systems.
