Helix M OneX (M – Series)

HELIX M ONE X

Ultra-Compact Monoblock Subwoofer Amplifier – High Power, Smart Integration

The HELIX M ONE X is a next-generation compact monoblock amplifier built to deliver massive 1,180 Watts RMS at 1 Ohm, all from a highly efficient and space-saving Class D design. Engineered for subwoofer applications, it is ideal for powering 2 x 2 Ohm subwoofers in parallel, while maintaining rock-solid stability and reliability.

Whether you’re installing it in a tight OEM location or building a competition-grade bass system, the M ONE X combines power, precision, and advanced technology for unmatched subwoofer control.

Extreme Power in a Tiny Package

Despite its compact footprint, the M ONE X packs an impressive punch with 1,180 Watts RMS output @ 1 Ohm. Designed using high-efficiency Class D technology, it handles low-impedance loads effortlessly, making it the perfect match for demanding subwoofer setups in both stock and custom installations.

Its minimal size simplifies installation in even the tightest spaces, while its robust thermal design keeps it running cool under pressure.

Designed for Serious Subwoofers

The M ONE X was built to unleash the full potential of your subwoofers. With massive current capability, it can easily power 2 x 2 Ohm dual voice coil subs wired in parallel, delivering tight, clean, and controlled bass even at high volumes.

Its active crossover section includes lowpass, bass boost, subsonic filter, and phase control—giving you all the tools to fine-tune your low-frequency response for any system and music style.

TwinPower Link – Combine Two for Double the Power

Looking for even more output? The TwinPower Link feature allows you to bridge two M ONE X amplifiers, creating a single powerhouse amplifier with doubled output capacity. This makes it easy to scale your system for higher SPL needs or future upgrades without replacing gear.

Smart Integration with OEM Head Units – ADEP Circuit

Thanks to the Advanced Diagnostics Error Protection (ADEP) circuit, the M ONE X integrates seamlessly with today’s factory audio systems. It prevents diagnostic errors and fader issues that commonly occur with basic aftermarket amps.

Plus, the auto turn-on function allows the amplifier to activate without needing a remote wire—simplifying integration and preserving OEM functionality.

Built for Modern Vehicles – Start-Stop Ready

The HELIX M ONE X is designed to work flawlessly with start-stop systems, maintaining full functionality even if voltage drops to 6V during engine cranking. No interruptions, no dropouts—just consistent bass performance no matter the conditions.

Wired Bass Remote for On-the-Fly Adjustments

Fine-tune your bass levels from the driver’s seat with the included wired remote control, offering quick and convenient subwoofer volume adjustment without reaching the amplifier.

Compact, Cool, and Reliable

Built using advanced SMD (Surface Mounted Device) technology, the M ONE X offers high power density, low heat output, and maximum reliability. The clean, modern design is complemented by low heat dissipation, making it perfect for stealth installs and tight enclosures.

Special Features

Smart High-Level Input with ADEP

Factory head units with built-in diagnostics can trigger errors when paired with traditional amps. The ADEP circuit ensures clean integration, avoiding warning messages and preserving factory fader and balance controls, even at high volume levels.

Start-Stop Capability

Thanks to its advanced DC-regulated power supply, the M ONE X continues to operate flawlessly during voltage dips down to 6V, ensuring uninterrupted performance during engine cranks or low-voltage events.
