Power Acoustik MICRO1-4000D 4,000W Class D Compact Monoblock Car Amplifier

Power Acoustik MICRO1-4000D 4,000W Class D Compact Monoblock Car Amplifier
The Power Acoustik MICRO1-4000D is designed for enthusiasts who need serious bass power without the bulk. Part of the MICRO Series, this amplifier delivers 4,000 watts of Class D monoblock power in a compact chassis only 3.5" wide, making it ideal for space-conscious installs that demand performance.
With 1-ohm minimum impedance stability, the MICRO1-4000D delivers 1,000W RMS at 1Ω and 750W RMS at 2Ω, providing flexible wiring options for powering subwoofers. Its hybrid aluminum alloy heatsink efficiently manages heat, while the MOSFET power supply with audiophile-grade IRTM transistors ensures clean, consistent output.
Engineered on a military-grade SMT PCB, this amplifier maintains dynamic performance under demanding conditions. Built-in protection circuits defend against shorts, thermal overload, and excessive current draw. For fine-tuning, the MICRO1-4000D features variable high-pass, low-pass, and subsonic crossovers, plus a 12dB bass boost for deep low-frequency impact. A dash-mount gain control module is included for quick level adjustments from the driver’s seat.
Installation is simple with 200mV–6V RCA inputs and bridged outputs, rugged 4-gauge power/ground terminals, and 8-gauge speaker outputs. Measuring just 3.5" W x 2" H x 9.75" L, the MICRO1-4000D proves that compact size can still deliver commanding bass.
General Features:
- High Efficiency Class D Monoblock Amplifier
- Compact 3.50” Wide Chassis Design for Installation Versatility
- Hybrid Aluminum Alloy Heatsink for Optimum Dissipation
- 1-ohm Minimum Impedance Class D Monoblock Operation
- MOSFET Power Supply w/ Audiophile Grade IRTM Transistors
- Military Grade SMT PCB Maintains Dynamic Performance
