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.

Great value and super cute!
Color: Gold, Size: 30-40-50mm, Color: Gold, Size: 30-40-50mm
These earrings are a yellow gold which I like, and they’ve held up really well the past few days in the shower and with daily wear. These feel high quality and as long as you arent rough with the clasps, these should last you a long time. These are affordable for the quality. I don’t think these will tarnish, and they haven’t lost any shine. The ones in the picture are the smallest size, but I love the others too. They are comfortable to wear and very light weight, whereas others I’ve tried have been heavy or not sturdy enough for daily wear. I would definitely recommend buying these!

Lovely earrings
Color: Silver, Size: 20-30-40mm
These earrings are thicker than what I wanted but they are so lovely and packaged so nicely that I am not going to return them. I will gift them to someone instead.

Very comfortable and light weight
Color: Gold, Size: 30-40-50mm
For what I would spend for one pair, I got three. Not knowing what size I wanted, I chose the three pack and I am glad that I did. I generally only wear stud earrings because of the weight and I don't like things dangling and touching me. So far, I have only used the smallest pair and like them. They are big for me but for most people probably wouldn't feel all that large. I am not certain that I will use the medium or large pairs but maybe some day I will feel dangerous. If you aren't sure what size you will feel comfortable with, I would suggest this package and try them all to see what your style might be. They are a good value and are light weight.
