MICRO4-1500D | 1500W Class D Compact 4-Channel Car Amplifier

Power Acoustik MICRO4‑1500D – 1,500W Class D Compact 4-Channel Car Amplifier

Don’t let its size fool you — the Power Acoustik MICRO4-1500D is engineered to deliver serious performance in a compact footprint. Part of the MICRO Series, this amplifier packs 1,500 watts of Class D full-range power into a chassis just 3.5" wide, giving installers flexibility without compromising output.

The MICRO4-1500D supports multiple setups: 4 x 80W RMS at 4Ω, 4 x 125W RMS at 2Ω, or 2 x 250W RMS bridged at 4Ω. Its hybrid aluminum alloy heatsink keeps heat under control, while a MOSFET power supply and audiophile-grade IRTM transistors ensure clean, consistent delivery at every level.

Built on a military-grade SMT PCB, this amplifier maintains dynamic performance under stress. Integrated protection circuits safeguard against shorts, overheating, and overload conditions. For precise tuning, the MICRO4-1500D features variable high-pass, low-pass, and subsonic crossovers, plus a 12dB bass boost for enhanced low-end response.

Installation is straightforward with 200mV–6V RCA inputs and bridged outputs, along with heavy-duty 4-gauge power/ground terminals and 8-gauge speaker outputs. At just 3.5" W x 2" H x 7.75" L, the MICRO4-1500D delivers powerful, efficient amplification where larger amps simply can’t fit.
