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.

Nice looking suit!
Size: Small, Color: Black, Size: Small, Color: Black
This suit fits my son perfectly & looks great! He is 5'9" & 145 lbs and I ordered a size Small. I was worried it would be big, but it looks & fits great! He'll be wearing it for his sister's wedding in the fall. We got a burnt orange vest, tie & pocket square to go with it. I can't speak to how wrinkle resistant it is since he hasn't worn it yet. My only complaint is that the breast pocket appears to be a fake pocket, so we cannot put a pocket square in it.

A good First Communion suit
Size: 6, Color: White, Size: 6, Color: White
This suit looks and feels really nice even though it’s not 100% linen. My son is an average size 7 year old, but I got a size 6 so that the fit would be nice and snug and not loose and baggy. It was the right choice. Comes with a bow tie which is nice, a tie (which is very cheap and poorly made) and a pocket square.

Very stylish💜💜
Size: 6, Color: Light Blue, Size: 6, Color: Light Blue
This little suit for boys is very stylish. I bought it for my grandson for a wedding occasion and it looked very nice. The fabric is not too thick so for the summer wedding it was great. I pick the blue color and it looked fantastic!
