The Hifonics A2000.1D is a Class-D monoblock car amplifier from the Alpha Series, built to drive a subwoofer. It is 1-ohm stable and rated at 500 watts at 4 ohms, 1000 watts at 2 ohms and 2000 watts at 1 ohm, with a compact chassis and an included bass remote. Ultra-Fi MOSFETs and electronic crossovers keep distortion low and efficiency high. It suits drivers who want strong subwoofer output from a small amp and plan to wire a dual-voice-coil sub down to 1 ohm. Against pricier monoblocks it trades premium parts and certified power figures for raw rated output and a small footprint.

Owners generally report the A2000.1D delivers solid subwoofer output for its size and like the included bass remote. Some question whether it truly makes its rated power and note it runs warm when pushed hard at low impedance.
The Hifonics A2000.1D is a monoblock Class-D car amplifier from the Alpha Series, built to power subwoofers. It uses a pulse width modulated MOSFET power supply and Ultra-Fi MOSFETs for efficient cooling and minimal distortion. It is stable down to 1 ohm.
Power output is 500 watts at 4 ohms, 1000 watts at 2 ohms and 2000 watts at 1 ohm, on one channel. Accu-Cross crossovers let you control the signal sent to the speakers. Preamp RCA outputs let you daisy chain multiple amps.
A wired remote for bass level control is included. LED indicators show power (green) and protect (red) status. Three-way protection covers thermal, overload and speaker short faults. A heavy-duty aluminum alloy heat sink helps with cooling.
