ETON MA1 — 1-Channel Monoblock Class-D Power Amplifier
The MA1 is ETON's monoblock amplifier for anyone building a serious subwoofer system without giving up cabin space. It's a compact, German-engineered Class-D design in a die-cast aluminium housing, built to punch well above its 270 x 160 x 51mm footprint.
Key features:
- High-output 1-channel monoblock: 690W RMS at 4Ω, 1120W RMS at 2Ω, 1510W RMS at 1Ω
- Advanced Class-D topology with ultra-low distortion (0.003% THD+N @ 100W, 60Hz) and a 96.5dB signal-to-noise ratio
- Adjustable active filtering — subsonic filter at 30Hz, low-pass filter adjustable 25–250Hz with selectable 12dB/24dB per octave slope
- Auto Sense-On turn-on via signal or DC detection, suited to vehicles with start-stop systems
- Dual high-level and dual low-level (RCA) inputs, with adjustable input voltage and resistance for clean gain-matching to factory or aftermarket sources
- Damping factor >340 @ 4Ω for tight, controlled bass response
- Stackable design — mount multiple MA1 units together for multi-amp builds
- Hidden mounting via blind holes, or adjustable mounting feet for standard installs
- Removable power and signal plugs for cleaner wiring and easier servicing
- LED status lightbar and a rotatable ETON logo (180°) on the removable cover, so the badge always sits the right way up regardless of mounting orientation
- Integrated adjustment tool included for on-the-fly filter and gain tuning
Who it's for:
Installers and enthusiasts building a high-output single-subwoofer or stacked-amp system who want German build quality, flexible tuning options, and a compact footprint that doesn't force awkward compromises in the install.
Fitment & installation notes:

- Mounting feet are adjustable, and blind-hole mounting points are available for a concealed install

- High-level cable adapter and mounting hardware included, so no separate purchase is needed for a standard install
