Description

The Hifonics A2000.1D ALPHA Series is a high-efficiency Super D-Class mono subwoofer car audio amplifier engineered to deliver up to 2000 watts of reliable power. It utilizes specialized Ultra-Fi MOSFET technology paired with a Twin Turbo Coil Pulse Width Modulated power supply to maintain stable voltage, reduce distortion, and maximize thermal cooling.

Precision sound tuning is achieved through integrated electronic Accu-Cross crossovers, an onboard subsonic filter, variable low-pass crossover, and 0 to 180-degree phase adjustment. Nickel-plated audio and power terminals provide secure, corrosion-resistant connections with high signal clarity and minimal external interference.

Built using robust Surface Mount Technology on a heavy-duty aluminum alloy heatsink, this amplifier withstands vehicle shock and vibration while effectively dissipating heat. It also includes DC Offset auto turn-on functionality via high-level inputs and comes complete with an HFR-31 wired bass remote for dash-mounted level adjustments.
