Match M 2.1 Amp Micro Amplifier Mono Subwoofer Mode or 2 Channel Stereo 350w RMS

The Match M 2.1AMP is a micro amplifier from the Match M series, switchable between 2-ohm stable mono mode (1 x 350W RMS) for subwoofers and 2-channel stereo mode (2 x 170W RMS at 4 ohms) for speakers. It measures just 35 x 85 x 110 mm, making it suited to stealth installs where space is tight.

Key specifications

• Mono mode: 1 x 350W RMS at 2 ohms, 1 x 210W RMS at 4 ohms (up to 430W RMS max at 2 ohms)
• Stereo mode: 2 x 170W RMS at 4 ohms
• Technology: Class HD
• Inputs: 2 x RCA, remote in (line input-to-RCA adaptor included)
• Frequency response: 10Hz–40kHz
• Signal-to-noise: 108 dB (A-weighted), THD < 0.02%
• Operating voltage: 10.5–17V, start-stop capable down to 6V
• Fuse: 1 x 30A LP-Mini
• Dimensions: 35 x 85 x 110 mm

Excellent sound quality combined with maximum efficiency

The M 2.1AMP is a compact amplifier for 1-channel or 2-channel use where installation space is limited. It runs as a 2-ohm stable mono subwoofer amplifier or as a stereo amp for passive component systems or power-hungry woofers. Despite its small footprint, it delivers up to 700W output power using Audiotec Fischer's proprietary Class HD technology, which maximises efficiency and keeps heat dissipation low.

Power on demand

Switchable mono/stereo operation makes the M 2.1AMP a versatile tool. In mono mode it drives powerful subwoofers down to 2 ohms; in stereo mode it suits front or rear speaker systems. Its High-Res audio bandwidth ensures an extended frequency response beyond 40 kHz in both modes.

Maximum flexibility in a minimum of space

Space for sound upgrades in modern vehicles is increasingly limited. At just 35 x 85 x 110 mm, the M 2.1AMP can be mounted in tight spots that rule out conventional amplifiers, opening up stealth installation options.

• Ultra-efficient Class HD amplifier with exceptional power-to-size ratio
• Mono mode: 1 x 350W RMS at 2 ohms — suits subwoofers with 2-ohm single voice coil (SVC2) or 4-ohm dual voice coil (DVC4)
• Stereo mode: 2 x 170W RMS at 4 ohms — suits front/rear speaker systems or under-seat subwoofers with 4-ohm single voice coil (SVC4)
• Small dimensions for hidden installation concepts
• Signal-to-noise ratio of 108 dB (A-weighted), THD < 0.02%
• 2-channel RCA/Cinch input
• "Ground Input" switch to avoid ground loops
• Perfect combination with Match UP 8DSP MK2 and other Match UPGRADE DSP amplifiers

Class HD technology

The M 2.1AMP combines Class H technology with a Class D amplifier topology. Internal supply voltage varies with the amplitude of the input signal, significantly reducing idle losses and keeping overall efficiency close to maximum at all times.

Start-Stop capability

The switched-mode power supply maintains a stable internal supply voltage even if battery voltage drops to 6V during engine crank, ensuring the amplifier operates reliably in start-stop equipped vehicles.
