Gladen ATM 2/4 Module

The Gladen ATM 2 / 4 module is a compact mono amplifier designed to easily convert passive subwoofer enclosures into active subwoofers. Thanks to its round design, the amplifier module can be integrated directly into the subwoofer enclosure in place of a conventional 78-mm connection terminal. This eliminates the need for a separate external power amplifier.

With an output power of 200 watts RMS, the ATM module provides sufficient power for compact, high-performance subwoofer solutions. It is available in two versions: the ATM 2 for 2-ohm subwoofers and the ATM 4 for 4-ohm subwoofers.

The integrated Class D amplifier technology enables efficient operation in a compact design. An adjustable low-pass filter and adjustable input sensitivity are available for custom sound tuning. Thanks to the high-level and low-level inputs, the module can be used with both factory-installed radios and aftermarket devices.

The automatic power-on function makes it easy to integrate the subwoofer into existing car audio systems. Power and input signals are supplied via the Molex Mini-Fit JR connector. In addition, the subwoofer level can be conveniently controlled from the driver's seat using the optionally available Gladen RTC2 remote control.
