Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!
Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

Manufacturer Information
HELIX M FOUR
If you like to turn up your front and rear speakers, the M FOUR is just the right tool for the job. With a generous 100 watts RMS per channel at 4 and 2 ohms, this amplifier will heat up your voice coils in no time at all despite its super-compact dimensions. At the same time, the M FOUR remains absolutely cool thanks to the highly efficient Class D design topology. 3- or 2-channel configurations are also possible and deliver up to 2 x 200 watts RMS of clean and undistorted output power.
Of course, the M FOUR is equipped with numerous intelligent functions such as start-stop function and our proprietary "ADEP" high level input, so that it easily masters all installation requirements of modern vehicles. The extensive audio functions ensure sound quality at its best.
Features
✓ Particularly compact Class D amplifier with high output power of 100 watts RMS at 4 and 2 ohms
✓ Start-stop capability down to 6V supply voltage
✓ Intelligent high-level input with ADEP circuit (Advanced Diagnostics Error Protection) and automatic switch-on
✓ Integrated, active crossover with high pass, low pass and band pass
✓ "Input Mode" switch for flexible distribution of the input signals
✓ SMD technology (Surface Mounted Device) combines minimum space requirement with maximum reliability
✓ Exclusive, very compact design with illuminated HELIX logo and low heat generation thanks to very high efficiency
Special features:
✓ Intelligent high-level input
The latest generation of standard car radios has sophisticated options for diagnosing the connected speakers. When connecting a conventional amplifier, error messages and the loss of certain functions (e.g. the fader function) often occur - not with the M FOUR.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without placing unnecessary strain on the speaker outputs of the standard radio at high volume.
✓ Start-stop capability
The power supply unit in the HELIX M FOUR amplifier ensures the internal power supply even in the event of short-term dips down to 6 volts. This ensures that the HELIX M FOUR remains fully functional even when the engine is started.
