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.

Best cabin filter I've ever used...
After my girlfriend dumped a container of Italian beef juice onto the passenger side floor mat and having it soak into the floor mat and the carpeting, it left my new car stinking of Beef gravy. I bought this to hopefully extract the annoying and horrible smell from my car. The filter is perfectly made and fit with exacting precision and minimal effort. If is well built and of superb quality, materials. The bright white cartridge style top side is pleated for maximum air to filter contact. The other side has these wonderful beads of activated charcoal/carbon that are for absorbing odors. As soon as I installed it and turned on my ventilation/ AC/Heat, I could smell the clean filter and also a sense of cleaner air. Hoping this will do the job in time!!

Good Fit & Fresh Air, But Slightly Reduced Airflow
I recently installed this cabin air filter in my 2024 4Runner, and it fits perfectly. It does a great job of filtering out the dusty Las Vegas air, leaving the cabin smelling fresh. However, I did notice a slight reduction in Airflow, on the highest blower setting, it feels like the output is about 25% lower than usual. It’s still early to tell how it will perform long term, but so far, it's doing its job well. If you prioritize air quality over maximum airflow, this is a solid choice at a good price too!

Filter fits well into cabin filter compartment of 2011 Toyota Avalon Limited.
Fits easily into my cabin filter slot of my 2011 Toyota Avalon Limited. It has performed well after a month of use. The design of this filter appears to be superior to the filters that are utilized at the Toyota dealer. The filter was easy to install via the back of the glove compartment.
