With the new AMPLIFY series, HELIX redefines modern amplifier design!

Instead of designing one amplifier to do everything, the Amplify series offers multiple models tailored for specific applications. This clear philosophy ensures that each model provides exactly what you need, and nothing more.

The Amplify series comes in three different versions: DIRECT, X-OVER, and DSP (DSP model will be available in summer 2025).

X-OVER models are the ideal choice for traditional installations in cars using either factory or aftermarket head units. These amplifiers feature, among other things, speaker-level inputs and extensive crossovers.

The signal in DIRECT models does not have to pass through crossover circuits, which allows for better sound quality and more precise adjustments. These amplifiers are intended for systems with a separate DSP device. As their name suggests, DIRECT series amplifiers have no crossovers at all; all adjustments are made with a separate DSP device.

The 2-Series is the most affordable line in the AMPLIFY series, still offering extensive features and incredible sound quality in a compact size.

The extensive crossovers of X-OVER model amplifiers can be switched off if needed, and adjustments can be made from the head unit or a separate DSP device. The signal can be fed to the device via RCA or speaker-level, and the device will wake up automatically if necessary (auto remote On / Off).

The Amplify 2-Series brings out every nuance of sound, exceeding the expectations of its price range in both sound quality and power.
