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.

Wiring wizard

Use our wiring wizard for simple wiring of speakers and subwoofers or to find the optimal setup for your cabinet! The right connection is important for your amplifier! Low impedance operation can damage the amplifier!

✓ Series connection: The impedance increases in number

✓ Parallel connection: The impedance decreases in the number

The data sheet shows you which connection the respective amplifier is designed for!

Port calculator

Our port calculator shows you which tuning your housing 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.

The net volume design for your woofer size in music mode can look like this

Bass reflex:

✓ 6.5" (16.5cm) = 10 - 15 liters

✓ 8" (20cm) = 20 - 30 liters

✓ 10" (25cm) = 40 - 50 liters

✓ 12" (30cm) = 60 - 80 liters

✓ 15" (38cm) = 100 - 125 liters

✓ 18" (46cm) = 180 - 240 liters

✓ 21" (54cm) = 230 - 290 liters

Manufacturers who provide data sheets or operating instructions can be found at the end of the item description for download.

Unfortunately, it is difficult to give a general answer, as all woofers and speakers are constructed differently and have different coils, plus the amplifier, which must be designed for the connection impedance. You can simply use our wiring assistant, enter the number of speakers, resistance and wiring variant and have it calculated. If the amplifier can handle the connection impedance, nothing stands in the way of the wiring.

Amplifiers which have a release up to e.g. 1 Ohm can also be connected with 2,3,4 and higher impedance.

If you prefer to listen to charts, rock, pop or e.g. techno, the tuning should be a little higher and is usually in the range of 40Hz and higher. The range of RnB or Ami HipHop usually plays in the 30 to 40Hz range.

In short, clipping is an "unclean signal". You can usually recognize clipping in woofers when there is an electrical smell, the woofer stinks and becomes hot. With loudspeakers, it can also be noticeable through unclean reproduction. The fun is over when the coil has unwound from the carrier. Many amplifiers now have a clipping LED integrated in the output stage or in the bass control; if the LED lights up, you should definitely turn down the volume. If the amplifier does not have an LED, the only way to position the gain correctly is to use an oscilloscope or other aids. However, this requires a certain amount of basic knowledge in order to set the amplifier correctly.

We almost exclusively offer products and manufacturers that we use ourselves and install regularly, true to the motto "quality not quantity", so we can usually tell you what to expect. All products are sensibly designed and selected to cover a wide range, for reasonable sound optimization and, above all, to achieve the desired goal. If you have any questions about your setup or plans, please contact us!
