If you want to get their front and rear speakers up to speed, then the M FOUR is just the right “tool” for it. With a whopping 100 watts continuous power per channel at 4 ohms as well as at 2 ohms, it heats the voice coils despite their super-compact dimensions. The amp itself stays cool thanks to its highly efficient Class D technology. But even in 3-channel or 2-channel configurations, with up to 2 x 200 watts RMS, it really gets down to business.
Thanks to the start-stop capability and the intelligent ADEP high-level input, the M FOUR can handle all the challenges that today’s vehicles pose when it comes to integrating an amplifier. And the perfect sound is also quickly found thanks to the integrated crossover and the extensive adjustment options.
Intelligent high-level input
Modern, factory-installed car radios are becoming increasingly intelligent in terms of diagnosing the connected speakers. If an amplifier is connected to the radio instead, it usually results in error messages up to the elimination of individual functions (such as faders). The new Advanced Diagnostics Error Protection (ADEP) circuitry eliminates all of these problems without unduly stressing the radio’s speaker outputs at high levels.
The power supply unit in the HELIX M FOUR amplifier ensures the internal power supply even with short-term drops down to 6 volts. This ensures that the HELIX M FOUR remains fully functional even when the engine is started.
