Bring serious power to your subwoofer system with the Alpine S2-A120M S Series monoblock Class D amplifier. Designed specifically for low-frequency applications, the S2-A120M delivers up to 1,200 watts RMS while maintaining a compact design for flexible vehicle installation.

The S2-A120M produces 600 watts RMS at 4 ohms and 1,200 watts RMS at both 2 ohms and 1 ohm, giving you the flexibility to match a wide range of subwoofer configurations. Its Class D amplifier design provides efficient power delivery while keeping the chassis relatively compact.

Built-in adjustable controls make it easy to tailor the amplifier to your subwoofer system. The variable low-pass filter can be adjusted from 50Hz to 400Hz with a 24 dB/octave slope, while the variable bass EQ provides up to 12dB of additional boost at 50Hz.

The S2-A120M also features a selectable remote turn-on circuit with three modes, helping it integrate with both factory and aftermarket audio systems. Side-mounted controls and connections make setup and adjustment more accessible when the amplifier is installed under a seat or in another space-conscious location.

With 1,200 watts of RMS power at 1 or 2 ohms, the S2-A120M is an ideal choice for powering a high-output subwoofer system or multiple compatible subwoofers.
