2-channel amplifier with integrated active crossover and 1 Ohm stability
The new G amplifiers are more than just impressive power packs. They unite innovative technology, extensive functionality and best sound with a very attractive price-performance ratio.
Beside their features such as fully active crossover with highpass, lowpass, bandpass and bass boost, input mode switch for flexible input signal routing and smart highlevel input with ADEP circuit, the G series also provides Start-Stop capability which is exceptional in this price range. And that’s not all – a remote control for adjusting the subwoofer level is included in delivery.
With such an extensive equipment the configuration of individual powerful but good sounding car audio systems is easy to realize. Furthermore the G amplifiers have the typical compact and straight HELIX design with illuminated logo.

Smart highlevel input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appears – but not with the G FOUR.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
The switched power supply of the HELIX G FOUR assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
