Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance.

Small, efficient and uncompromisingly stable - the M ONE X 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 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 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.

  • 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 6V supply voltage
  • Smart highlevel input with ADEP circuit and Auto Turn-On function
  • Integrated, active crossover with lowpass, bass boost, subsonicand 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.
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 assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.

Not the best
Size: 7, Color: Black, Size: 7, Color: Black
They are cute but they have a bit of an odd fit that isn’t great for people with narrow feet. They look too dressy to wear with super casual outfits in my opinion. I think the Ugg golden star sandals are much comfier. If you’re wearing these sandals for a really short time they’d be okay. After wearing them around my house for a little while I decided to return them since they started to hurt my feet.

Not for narrow feet, very lightweight.
Size: 7.5, Color: Black
My feet are slightly narrow; these were not adjustable enough to make secure. Otherwise they are cute. The material feels kind of light, these were my first attempt at UGGs so I'm not sure if that's typical or an actual quality issue. Either way, they don't seem very durable but I can't imagine these are meant for roughing it.
