If you like to rev up your front and rear speakers, the Helix M FOUR will be exactly the right "tool" to do so. With generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load this amp will heat up your voice coils in no time despite its super-compact dimensions. On the other hand, the M FOUR stays totally cool thanks to the highly efficient Class D design topology. 3-channel or 2-channel configurations are possible as well, delivering up to 2 x 200 Watts RMS of clean and undistorted output power.

Needless to say that the M FOUR is equipped with a bunch of intelligent attributes like "start-stop capability" and our proprietary "ADEP" high-level input so that it easily deals with all installation challenges of modern cars. Finally, the extensive audio features will offer sound quality at its best.

Smart high-level input

The latest generation of OE car radios incorporates sophisticated possibilities for diagnosing connected speakers. If a common amplifier is hooked up failure messages and loss of specific features (e.g. fader function) often appear - but not with the M FOUR.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without unnecessarily loading the OE radio speaker outputs during high volumes.

Start-Stop capability

The switched power supply of the HELIX M FOUR assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
