Alpine HDA-M80 Status Class D mono amplifier for subwoofers
The Alpine HDA-M80 brings Status Series sound quality to your car's bass system. This Class D mono amplifier featuring Sierra-H technology delivers 800 W RMS into a 2-ohm load and 500 W RMS into a 4-ohm load at 14.4 V. The frequency response extends from 8 Hz to 400 Hz.
When you want to tailor the bass to different music genres, the adjustable subsonic filter, subsonic filter, and Bass EQ provide the tools to fine-tune the subwoofer's performance. An separately sold level control allows you to adjust the subwoofer level from the listening position.
Status Series construction and Sierra-H technology
The Alpine Status Series utilizes technologies, components, and materials familiar from the F#1 Status Series in a more affordable package. Status System components can be purchased separately, and the series is designed for music playback of up to 192 kHz / 24 bits.
The HDA-M80's Sierra-H technology compares and corrects the signal twice during analog signal conversion. A copper chassis protects the audio signal from external interference. The amplifier features a black circuit board, a signal-to-noise ratio of over 107 dB, and less than 0.02% THD+N under stated test conditions.
Installation and thermal management
The power and ground terminals, speaker outputs, RCA inputs and outputs, level control connection, and fuses are all located on the same side. Compact screw terminals make it easy to connect cables. The controls are located on top of the amplifier under a protective cover, and a blue LED light completes the look.
Advanced thermal management and a protection circuit monitor the amplifier's operating temperature.
Compatible level control
Alpine RUX-KNOB2 makes it easy to adjust the subwoofer level. The level control is sold separately.
