HELIX AMPLIFY 204 X-OVER

HELIX AMPLIFY

HELIX AMPLIFY - Powerful. Clear. Consistent.
With AMPLIFY, HELIX redefines the standard for modern amplifier design: through the contemporary interpretation of classic concepts. Instead of "one-fits-all" solutions, AMPLIFY focuses on specialized models that are precisely tailored to different areas of application. This stringent philosophy guarantees: Each model delivers maximum performance for its intended use - while concentrating on the essentials.

The 2-series marks the entry into the AMPLIFY platform - and at the same time forms its technical and sonic core. These compact Class D amplifiers combine power, a fully bridgeable multi-channel architecture and outstanding efficiency with practical integration capability. Brilliant and precise highs, controlled mids and tight, powerful bass - the 2-series brings all facets of natural and powerful sound to any vehicle with sound quality and performance values far above the expectations of its class. Whether as a DIRECT, X-OVER or DSP variant (from summer 2025): From flexible 6-channel configurations for full-range applications to the powerful 1-channel subwoofer powerhouse, everything is on offer.

AMPLIFY 204 - The versatile solution for full-range applications
The AMPLIFY 204 amplifiers combine four fully bridgeable outputs with excellent sound and impressive performance - ideal for powerful front or multi-channel setups. Whether classic 4-channel operation, 3-channel configuration with subwoofer or bridged 2-channel solutions: The 204 flexibly adapts to the requirements of a wide variety of vehicles and system designs. With an output of 4 x 100 watts RMS at 4 Ω, 4 x 190 watts RMS at 2 Ω or 2 x 380 watts RMS bridged at 4 Ω, it offers more than enough power for ambitious setups. In the X-OVER version with active crossover or as a DIRECT model for purist operation with external DSPs - the focus is always on high-quality sound performance.

Sound and performance - above the standard
The AMPLIFY 2 series not only stands for perfectly tailored solutions for different applications, but also for the clear goal of far exceeding the expectations of its class in terms of sound and performance in each of these applications. All amplifiers in the series offer brilliant sound quality, low distortion and outstanding signal-to-noise ratios - paired with fully bridgeable multi-channel outputs for maximum performance and installation flexibility. The result: a series that does not define itself by its class, but sets new standards in it - making it the first choice for anyone looking for application-oriented performance without compromise.

AMPLIFY X-OVER - Maximum flexibility for classic upgrades
The AMPLIFY X-OVER models are the ideal choice for conventional sound upgrades with factory radios or retrofit head units. The focus is on the integrated, active crossover with high-quality, adjustable high and low-pass filters and input mode switch - it enables precise signal tuning and facilitates the implementation of a wide variety of system configurations. Whether for an active front system with separate control of tweeters and woofers, the operation of passive front and rear systems or the combined use of a front system with subwoofer via bridged channels: The X-OVER models offer maximum flexibility in system design. Switchable high-level and RCA inputs with up to 16 V input sensitivity enable integration into almost any factory or retrofit environment. The integrated ADEP.3 circuitry ensures error-free communication with OEM radios, while an automatic switch-on function minimizes installation effort. As an additional feature, the DirectDSP function allows the input signal to bypass the crossover unaffected and pass directly to the power amplifier - ideal for anyone who wants to upgrade their system with an external DSP at a later date.

Form follows function
The design of the HELIX AMPLIFY 2 series combines modern functionality with a clear, technical look. The compact dimensions allow flexible installation, even in confined spaces. A removable cover conceals connections and operating elements, providing additional protection and creating a tidy, high-quality overall impression. Matt surfaces, precise lines and a minimalist design language ensure a stylish, exclusive look that blends seamlessly into any modern vehicle interior.
