Helix M One (M – Series)

HELIX M ONE

Compact Monoblock Subwoofer Amplifier – Efficient Power for Deep Bass

The HELIX M ONE is a high-performance, compact monoblock amplifier engineered for subwoofer applications that demand precision and power. Delivering a solid 600 Watts RMS at 1 Ohm, this amp is a perfect match for 2 x 2 Ohm subwoofers wired in parallel. Designed using the latest Class D technology, the M ONE offers remarkable current capability and power efficiency in a compact footprint.

Whether you’re integrating it into a tight installation or building a competition-level sub setup, the M ONE ensures powerful, distortion-free bass with unmatched stability and reliability.

Ultra-Compact Design with Massive Output

The space-saving design of the M ONE makes it easy to install in virtually any vehicle, yet its performance is anything but small. Its Class D amplifier topology ensures high efficiency, low heat output, and maximum stability, even at 1 Ohm loads—delivering serious bass without compromising on space or reliability.

With a clean and modern design, illuminated HELIX logo, and premium build quality, it’s a perfect fit for custom installs and OEM system upgrades alike.

Optimized for Subwoofers – Clean, Deep, Controlled Bass

The HELIX M ONE was purpose-built to power low-frequency speakers with clarity and control. With 600 Watts RMS output @ 1 Ohm, it delivers the high-current output needed to drive large subwoofers to their full potential.

The amplifier’s integrated lowpass crossover, bass boost, subsonic filter, and phase control offer total control over your bass tuning, letting you refine your subwoofer response for every genre and vehicle cabin.

Smart High-Level Input with ADEP Circuit

Thanks to the Advanced Diagnostics Error Protection (ADEP) circuit, the M ONE integrates flawlessly with modern OEM head units, avoiding errors like fader issues or diagnostic faults that occur with basic amplifiers. It includes auto turn-on functionality, simplifying installation without additional remote wires or triggers.

This makes the M ONE ideal for OEM integration while preserving full vehicle functionality and audio performance.

Start-Stop Compatibility for Modern Vehicles

The HELIX M ONE is engineered with start-stop system support, operating reliably even when vehicle battery voltage dips to 6V during engine cranking. This ensures uninterrupted subwoofer performance, no matter the driving conditions.

Precision Tuning with Included Bass Remote

For on-the-fly bass adjustments, the M ONE includes a wired bass remote control, giving users easy access to subwoofer volume without needing to access the amplifier directly. Whether you’re switching from hip-hop to classical or fine-tuning your setup, the control is always at your fingertips.

High-Efficiency Build with Premium Components

Built using SMD (Surface Mounted Device) technology, the HELIX M ONE features a robust PCB layout, high-current output transistors, and thermally efficient construction. This not only maximizes reliability but also ensures consistent performance in demanding installations.

Special Features

Smart High-Level Input with ADEP

Modern car radios often monitor speaker outputs for diagnostic signals. The ADEP circuit prevents error messages and loss of features by ensuring clean, safe integration with factory head units, even at high volume levels.

Start-Stop Ready

Thanks to a regulated power supply, the M ONE maintains full functionality down to 6V, ensuring your subwoofer keeps pumping even when the engine is cranking or under voltage stress.
