Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!
Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.
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 every 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 201 - The specialists for subwoofer performance
Uncompromising bass power in the smallest of spaces: The AMPLIFY 201 monoblocks have been specially developed for use as subwoofer amplifiers and deliver superior performance with a high level of control - ideal for powerful bass reproduction with maximum precision. With up to 750 W RMS at 1 ohm, adjustable subsonic and low-pass filters and adjustable phase position in the X-OVER version, or an uncompromisingly pure signal path in the DIRECT version, as well as their compact design, the AMPLIFY 201 are the ideal choice for targeted subwoofer upgrades in modern sound systems.
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 DIRECT - Developed for use with external DSPs
Thanks to their DirectDSP inputs, the DIRECT models have been specially developed for use in signal processor-based audio systems that require clean, efficient and transparent amplification. In particular, the focus on technical elementary control elements and high-quality components results in error-free commissioning. By dispensing with conventional input filters, the signal remains undistorted and therefore as clear as possible. The high-quality gain stage with clipping LED enables precise level adjustment, while the reduced input circuit effectively minimizes interference and distortion. A practical stereo/mono switch for each stereo input also allows bridged operation with just one RCA signal - without the need for external Y adapters.
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.
