The new HELIX D amplifiers open new horizons in terms of price performance ratio. It is the first time that HELIX offers a lot of amplifier performance for such a low budget without neglecting the proved HELIX quality. Both power packs convince at first sight through high-quality processing in many details. The fine brushed aluminum heatsink and the stylish HELIX-logo make these models very attractive.

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 D 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.
