Designed with purpose. Engineered to amplify what matters
With the AMPLIFY series, HELIX redefines the idea of modern amplifier design – by reinterpreting classic concepts through the lens of today’s audio demands. At the heart of AMPLIFY lies a clear mission: maximum sound performance. Across all variants, the series delivers brilliant sound quality, extremely low distortion, and an outstanding signal-to-noise ratio – paired with fully bridgeable multi-channel outputs for maximum flexibility in real-world installations. Thanks to a modular and scalable architecture, AMPLIFY is designed to grow – from value-driven everyday heroes to advanced professional tools. This is where clarity, control and acoustic precision meet. True to the principle: Performance by Design.
AMPLIFY 2-Series: Ambition meets efficiency
The 2-Series marks the entry into the AMPLIFY platform – and forms its technical and tonal CORE. These high-performance Class D amplifiers combine superior output power with refined sound characteristics, exceeding all the stats you would usually expect in their class. Brilliant and precise treble, a controlled mid-range as well as tight, powerful bass – the 2-Series brings all facets of pure natural and powerful sound to every vehicle. Available as DIRECT, X-OVER or DSP versions, the 2-Series reflects what AMPLIFY is all about: genuine sound quality, made accessible – right from the start.

A tailored solution for every application
Rather than designing one amplifier to do everything, we created three specialized models, each tailored for a specific type of application. This ensures the best possible performance – no compromises. Whether you’re integrating into an OEM system, pairing with an external DSP, or looking for a complete all-in-one solution: AMPLIFY gives you exactly what you need – and nothing you don’t.
DIRECT – Made for external DSPs
The DIRECT models, featuring their DirectDSP inputs, are purpose-built for use in DSP-based audio systems that demand clean, efficient and transparent amplification. By eliminating conventional input filtering, they ensure uncompromised signal integrity and maximum clarity throughout the signal path. A high-quality gain stage and clipping LED enable precise level adjustment, while the minimalist input architecture keeps noise and distortion to an absolute minimum.
X-OVER – Maximum flexibility for conventional upgrades
X-OVER models are the ideal choice for conventional sound upgrades using factory or aftermarket radios. Switchable high level and RCA inputs allow seamless integration into a variety of system configurations. The integrated active crossover enables precise signal tuning, by offering high-quality 12 dB high- and lowpass filters, phase control (mono blocks only), an Input mode switch and a included remote control option (mono blocks only). In additon, the integrated ADEP.3 circuit prevents error messages in OEM systems, making X-OVER models a versatile and integration-friendly solution.

DSP – Compact power, full control
These all-in-one amplifiers combine strong output with an integrated DSP, offering full control via the DSP PC-Tool. Ideal for compact, processor-based systems, they allow detailed tuning without the need for external components – perfect for OEM upgrades or tight installations
