What is a DUMAN Sub Out?

Upgrade to a louder audio system without changing your factory head unit with the DUMAN SUB OUT-Module. This device acts as an Hi Lo Converter, allowing you to easily connect a subwoofer to your existing head unit. The DUMAN SUB OUT-Module also adds an amplifier output, giving you even more control over the sound of your system. With this device, you can enjoy all the benefits of a subwoofer without the need for a costly head unit upgrade.

For optimal performance, we recommend installing the DUMAN Sub Out-Module directly behind your head unit. This will allow the device to act as an amplifier and make it easier for you to tap power from your speakers. If you choose to install the Sub Out-Module elsewhere, such as next to the amplifier, you will need to extend the wires to reach your factory speaker wires.

One of the standout features of the DUMAN Sub Out-Module is its clever technical design, which allows it to turn on the amplifier only when you are using your speakers. This helps to conserve energy and prevent unnecessary wear and tear on the amplifier. The module has a power output of up to 50mA, which activates the amplifier only when in use. When not in use, both the module and amplifier will remain turned off.


  • Remote output: The Sub-Out Module has a remote output of up to 50mA, which activates the amplifier when in use.
  • Built-in noise filter: The module is equipped with a built-in noise filter to eliminate any unwanted noise or interference.
  • Compatibility: The Sub-Out Module is designed to work with factory head units and can be easily installed without the need for any modifications.

The DUMAN Sub Out-Module is designed to conserve energy and prevent unnecessary wear and tear on the amplifier. It only turns on the amplifier when there is music playing, so you won’t have to worry about a flat battery. Additionally, the built-in noise filter eliminates ground loop buzzing noise, ensuring a high-quality audio experience.

New features in V1.0:

  • Automated REM-Output: The Sub Out-Module now automatically activates the amplifier when in use, making it even easier to use and conserve energy.
  • Noise filter: The built-in noise filter instantly removes any interference or buzzing noise, ensuring clear and uninterrupted sound quality.
