A 2-channel Class HD micro amplifier from Match, the M 2.1AMP delivers 1 x 350W RMS at 2Ω in mono mode or 2 x 170W RMS at 4Ω in stereo mode (up to 430W RMS maximum at 2Ω), with 2 RCA inputs (1-6V), mono/stereo mode switch, ground input switch, frequency response to 40kHz, 108dB SNR, Class HD technology for maximum efficiency, Start-Stop capability, and an ultra-compact 35 x 85 x 110mm housing suited to stealth installation concepts.
The Match M 2.1AMP is the compact power amplifier companion to the Match M 5.4DSP, sharing the same 35 x 85 x 110mm micro dimensions for stealth installation concepts in modern vehicles where space is severely limited. The M 2.1AMP is a multifunctional tool that switches between mono and stereo operating modes, making it ideal for subwoofer amplification, front or rear speaker amplification, and DVC subwoofer applications from a single unit.
In mono mode the M 2.1AMP operates as a 2Ω stable mono amplifier delivering 1 x 210W RMS at 4Ω and 1 x 350W RMS at 2Ω (up to 430W RMS maximum), suited for single voice coil subwoofers at 2Ω or dual voice coil subwoofers with both coils wired in parallel. In stereo mode it delivers 2 x 170W RMS at 4Ω for driving powerful front or rear speaker channel pairs including passive component systems and power-hungry midbass drivers.
The Class HD topology combines the dynamic supply rail modulation of Class H technology with the switching efficiency of Class D, continuously varying the internal supply voltage to minimise idle losses and maintain efficiency close to maximum at all times. The resulting heat dissipation is minimal, enabling the compact micro form factor without thermal management limitations. The High-Res audio bandwidth of 10Hz to 40kHz ensures that all audio content, including high-resolution sources, is reproduced without bandwidth limiting at the amplifier stage.
The 2 RCA inputs accept 1-6V from DSP processors, aftermarket head units, and the RCA outputs of Match UPGRADE DSP amplifiers such as the M 5.4DSP. The ground input switch prevents ground loop noise in multi-amplifier installations. The Line Input-to-RCA adaptor is included for flexible connection. Start-Stop capable power supply maintains stable operation during voltage drops to 6V. Operating voltage is 10.5-17V. Fused at 1 x 30A LP-Mini (APS).
Mono Mode - 1 x 350W RMS at 2Ω for Subwoofer Applications: In mono mode the M 2.1AMP delivers 1 x 210W RMS at 4Ω and 1 x 350W RMS at 2Ω (up to 430W RMS maximum), providing substantial power for driving single voice coil subwoofers at 2Ω and DVC subwoofers with coils wired in parallel.
Stereo Mode - 2 x 170W RMS at 4Ω for Speaker Applications: In stereo mode the M 2.1AMP delivers 2 x 170W RMS at 4Ω for driving powerful front or rear speaker channel pairs, passive component speaker systems, and high-efficiency midbass drivers.
Class HD Technology - Maximum Efficiency with Minimal Heat Dissipation: Class HD varies the internal supply voltage in real time depending on the amplifier's input signal amplitude, reducing idle losses and maintaining overall efficiency close to maximum at all times. The resulting low heat dissipation enables the compact micro form factor without requiring large heatsinks or active cooling.
Ultra-Compact 35 x 85 x 110mm - Micro Form Factor for Stealth Installations: The M 2.1AMP shares the same 35 x 85 x 110mm dimensions as the Match M 5.4DSP, enabling installation in locations impossible for conventional amplifiers including under seat rails, inside door panels, behind dashboards, and in OEM cavity spaces typical of modern vehicles.
High-Res Audio Bandwidth - 10Hz to 40kHz: The extended frequency response of 10Hz to 40kHz with 108dB SNR and THD below 0.02% provides High-Resolution audio bandwidth, ensuring lossless signal reproduction across the full range of high-resolution audio content without bandwidth limiting at the amplifier stage.
Ground Input Switch - Ground Loop Prevention: The ground input switch provides a solution for ground loop noise in multi-amplifier installations, preventing hum and interference in complex system configurations where multiple amplifiers share the signal source.
Perfectly Combinable with Match UPGRADE DSP Amplifiers: The M 2.1AMP is specifically designed to pair with Match UPGRADE DSP amplifiers including the M 5.4DSP, connecting to the RCA line outputs of the DSP amplifier for additional channel power in multi-amplifier system architectures.
2 RCA Inputs (1-6V): Accepts line-level RCA signals from DSP processor outputs, aftermarket head units, and Match DSP amplifier RCA outputs for maximum system flexibility.
Start-Stop Capable - 10.5-17V Operating Range: Start-Stop capable power supply maintains stable internal supply voltage during voltage drops to 6V for up to 5 seconds during engine cranking.

The M 2.1AMP is compatible with 10.5-17V vehicle electrical systems. RCA inputs accept 1-6V from DSP processor outputs, aftermarket head units, and Match UPGRADE DSP amplifier RCA outputs. The M 2.1AMP has no high-level inputs and no RCA preout. Designed for use with Match M 5.4DSP and other Match UPGRADE DSP amplifiers as an expansion amplifier for additional output channels. Confirm subwoofer impedance matches the 2Ω (mono) or 4Ω (stereo) rated output configurations before purchase.
What is the difference between mono and stereo mode on the M 2.1AMP?
In mono mode the M 2.1AMP operates as a 2Ω stable mono amplifier delivering 1 x 350W RMS at 2Ω (up to 430W RMS maximum), with both RCA inputs summed to a single mono channel. This is ideal for driving single voice coil subwoofers at 2Ω or DVC subwoofers with both coils wired in parallel. In stereo mode it delivers 2 x 170W RMS at 4Ω for front or rear speaker channel pair applications.
Is the M 2.1AMP compatible with the Match M 5.4DSP?
Yes. The M 2.1AMP is specifically designed to pair with the Match M 5.4DSP, connecting to the DSP amplifier's RCA line outputs to provide additional output power for subwoofer or high-power speaker applications in multi-amplifier system configurations. Both units share the same compact micro dimensions for uniform stealth installation concepts.
Does the M 2.1AMP have any onboard crossover filters?
No. The M 2.1AMP has no highpass, lowpass, or subsonic filter controls. All crossover and signal processing must be handled by the upstream DSP amplifier or processor.
What is Class HD technology?
Class HD combines the dynamic supply rail modulation of Class H technology with the switching efficiency of Class D output stage design. By continuously varying the internal supply voltage in response to the input signal amplitude, idle losses are dramatically reduced and overall efficiency is maintained close to maximum at all times, resulting in minimal heat dissipation from the compact micro housing.
Is the M 2.1AMP suitable for driving passive component speakers?
Yes. In stereo mode the M 2.1AMP delivers 2 x 170W RMS at 4Ω with a 10Hz-40kHz frequency response and 108dB SNR, making it well suited for driving passive component front or rear speaker systems where high power output and High-Res audio bandwidth are required.
