The HELIX AMPLIFY 201 X-Over is a compact 1-channel digital amplifier designed for subwoofer applications in OEM upgrades and custom audio systems. Engineered to deliver controlled and efficient low-frequency power, it is ideal for adding dedicated bass performance to systems where space and integration flexibility are key.
Built with high-efficiency Class D technology, the AMPLIFY 201 X-Over provides stable output even at low impedance, ensuring reliable performance in demanding setups. It features integrated active crossovers, allowing precise adjustment of low-pass filtering directly on the amplifier. This simplifies system design and ensures optimal subwoofer performance without requiring external processing in simpler installations.
With the AMPLIFY series, HELIX redefines the idea of modern amplifier design – by reinterpreting classic concepts through the lens of today’s audio demands. Rather than designing one amplifier to do everything, the focus lies on specialized models, each tailored for a specific type of application. This clear philosophy ensures every variant delivers exactly what’s needed – and nothing you don’t.
The 2-Series marks the entry into the AMPLIFY platform – and forms its technical and tonal core. These compact Class D amplifiers combine powerful performance, a fully bridgeable multi-channel architecture, and excellent efficiency with seamless real-world integration. Brilliant and precise treble, a controlled mid-range as well as tight, powerful bass – the 2-Series brings out every nuance of natural, powerful sound, outperforming the expectations of its class in both sound quality and output. Whether as a DIRECT, X-OVER, or DSP variant (coming in summer 2025): from flexible 6-channel setups for fullrange applications to dedicated mono powerhouses for subwoofers – the 2-Series offers tailored solutions for every configuration.
AMPLIFY 201 – The specialists for subwoofer performance
Uncompromising bass power in a compact format: The AMPLIFY 201 monoblock amplifiers are specifically designed for subwoofer upgrades and deliver powerful output with excellent control – ideal for deep, dynamic bass with maximum precision. With up to 750 W RMS at 1 Ohm, adjustable subsonic and lowpass filters, and phase control in the X-OVER version – or an uncompromised signal path in the DIRECT model – along with their compact footprint, the AMPLIFY 201 amplifiers are the perfect choice for targeted subwoofer upgrades in modern sound systems.
Sound and power – above the standard
The AMPLIFY 2-Series is more than just a range of application-specific solutions – it's a clear commitment to a very specific mission: to outperform expectations in each of those applications – both in sound quality and power delivery. All amplifiers in the series offer brilliant sound performance, minimal distortion, and an outstanding signal-to-noise ratio – combined with fully bridgeable multi-channel outputs for maximum output and installation flexibility. The result: a lineup that doesn’t define itself by its class, but sets new benchmarks within it – making AMPLIFY the first choice for those seeking application-focused performance without compromise.
AMPLIFY X-OVER – Maximum flexibility for classic upgrades
X-OVER models are the ideal choice for traditional sound upgrades using factory or aftermarket radios. Switchable high-level and RCA inputs allow seamless integration into a wide range of system configurations. The high-level input is designed for input voltages up to 32 V, ensuring maximum compatibility with modern factory head units and premium sound systems. In addition, an integrated auto turn-on function enables the amplifier to also be activated via the music signal – without the need for a separate remote line. The integrated active crossover enables precise signal tuning, by offering high-quality 12 dB lowpass and subsonic filters, phase control, an Input mode switch and an included remote control option. In addition, the integrated ADEP.3 circuit prevents error messages in OEM systems, making X-OVER models a versatile and integration-friendly solution
Form follows performance
The design of the HELIX AMPLIFY 2-Series blends modern functionality with a refined, technical aesthetic. Its compact dimensions allow for flexible installation, even in tight spaces. A removable top cover conceals all connections and controls, offering additional protection as well as a clean and streamlined appearance that highlights the amplifier’s high-quality character. Matte surfaces, sharp contours, and a minimalist design language create a sleek, exclusive look that integrates seamlessly into any modern vehicle interior.
