We’re in a time where small is “in.” Smaller, more economic vehicles are more and more desirable. But that doesn’t mean you have to sacrifice big power for your system. Razor amplifiers pack huge power into small chassis thanks to efficient Full-Range Class D topology and SMT circuitry. Complimented with every possible preamp adjustment, the Razor amplifiers leave nothing to be desired…

Are you using an original or factory radio? No problem. These amplifiers are equipped with Automatic Hi-Level Signal Sensing Turn-On. There's no need for a remote wire—this amp detects the audio signal and powers on automatically (Hi-Level Input only).

Compact Build, Aggressive Output

The RZ1‑3500D drives up to 2,100 watts RMS at 1 ohm, ideal for handling powerful subwoofers. Built with a MOSFET power supply and a military-grade SMT PCB, it offers stability, consistent output, and heat efficiency in a compact design only 1.625″ tall—perfect for tight spaces and stealth installs.

  • RMS Power:
    • 900W @ 4Ω
    • 1,400W @ 2Ω
    • 2,100W @ 1Ω
  • Peak Power: 3,500W Max
  • Chassis Dimensions: 12.25″ × 4.75″ × 1.625″

Audio Integration & Control

Whether you're installing in a factory stereo setup or a custom head unit, this amplifier is ready:

  • High-Level Speaker Inputs with auto turn-on
  • Low-Level RCA Inputs (0.25V–6V sensitivity)
  • Wired Remote Gain Control included

Built-In Protection & Tuning

Designed to protect your system while giving you control over every detail:

  • 3-Way Protection Circuitry: thermal, overload, and speaker short
  • Variable Low-Pass Crossover (35–250 Hz)
  • Subsonic Filter (10–50 Hz)
  • 12 dB Bass Boost with frequency tuning

Designed for Performance

The Class D monoblock topology ensures efficient, low-heat operation, even under sustained load. Whether you're competing, cruising, or just want clean, hard-hitting bass—this amp handles it.

The RZ1‑3500D is a standout in the Power Acoustik Razor Series, delivering power without bulk and control without complication.
