Power Acoustik RZR4‑1500D Razor Series 4-Channel Class D Full-Range Amplifier – Compact Chassis, Big Output
The Power Acoustik RZR4‑1500D brings serious multi-channel amplification into a space-saving, vehicle-friendly format. Part of the Razor Series, this Class D 4-channel amplifier offers a smart solution for sound builders who require consistent 1500W peak output without sacrificing install versatility.
Designed for compact cars, trucks, and SUVs, the RZR4‑1500D fits nearly anywhere—under seats, behind panels, or in tight trunk setups. Despite its small footprint, this full-range amp delivers crisp highs, punchy mids, and solid low-end output across all four channels.
Precision Meets Power: Configurable Output for Any Setup
Rated at 60 watts RMS per channel at 4 ohms, 100 watts x4 at 2 ohms, and capable of 200 watts x2 bridged at 4 ohms, this amp adapts to multiple configurations—door speakers, tweeter arrays, rear fill, or subwoofer bridging.
Built using SMT technology and a MOSFET power supply, it’s engineered for durability, thermal stability, and efficient operation. Signal processing includes variable high-pass and low-pass crossovers (defaulted to 80Hz), offering the control needed to properly tune frequency distribution per channel.
Integrated Smart Features: No Remote Turn-On Wire Required
Thanks to signal-sensing high-level input, the amp detects incoming sound from a factory stereo system and powers on automatically—no remote turn-on wire needed. That makes it a direct fit for OEM upgrades, especially when retaining factory head units.
The balanced RCA low-level inputs support up to 6V signal input, ensuring clean signal transmission from aftermarket receivers. All terminals are 8-gauge direct-connect—no adapters needed, minimizing resistance and signal loss.
