HELIX M ONE X – 24V Edition
Small, efficient and uncompromisingly stable – the M ONE X – 24V Edition is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE X – 24V Edition a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel. And for even more output power, two M ONE X – 24V Edition amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.
In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.

Features
Small footprint Class D amplifier with up to 1,180 Watts RMS output power @ 1 Ohm for easiest combination with all 2 x 2 Ohms subwoofers connected in parallel
Start-Stop capability down to 12V supply voltage
Smart highlevel input with ADEP circuit and Auto Turn-On function
Integrated, active crossover with lowpass, bass boost, subsonic and phase control
TwinPower Link for connecting two amplifiers in bridged mode
Bass remote control for volume adjustment
Low heat dissipation thanks to extraordinary efficiency
Special features
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 appear – but not with the M ONE X – 24V Edition.
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.

Start-Stop capability
The switched power supply of the HELIX M ONE X – 24V Edition assures operation even if the battery’s voltage drops down to 12 Volts during engine crank.
