Eton MA1 Monoblock Class D Power Amplifier

ETON MA 1 – 1-Channel Monoblock Class-D Power Amplifier

The ETON MA 1 is a newly developed Advanced Class-D monoblock that punches way above its footprint. Measuring just 270 x 160 x 51mm, it slips into tight install spaces without sacrificing a single watt — delivering up to 1510W RMS at 1Ω from a housing that barely takes up any room. If you're building a serious subwoofer system and need clean, stable, high-output power with zero drama, this is it.

Built in a premium gunmetal die-cast aluminium housing with a removable cover, integrated adjustment tool, LED status lightbar, and stacking capability — the MA 1 is engineered to the same German standards ETON is known for across their entire lineup.

Pair with the ETON MW 12 (2x2Ω DVC) wired to 1Ω for maximum output — a natural match.

📋 Specifications

💡 Who Is the MA 1 Built For?

The MA 1 is designed for anyone running a dedicated subwoofer channel who refuses to compromise on quality. The 1Ω stability at 1510W RMS makes it perfect for driving a dual voice coil sub like the ETON MW 12 wired down to 1Ω for maximum output. The high-level inputs mean it plays nicely with factory head units — no aftermarket HU required. And with start-stop vehicle compatibility, it's fit for modern 4x4s, Navara, HiLux, Prado — whatever you're running.

At just 51mm tall, it tucks away under seats, in custom enclosures, or behind panels without eating into your boot space. Clean, compact, powerful — this is what a German-engineered monoblock looks like.
