STEG DST1000DII

The STEG DST1000DII is a powerful and compact 1-channel Class-D amplifier designed specifically for the demanding task of driving subwoofers. With an output power of 1,000 watts RMS at 2 ohms and 500 watts RMS at 4 ohms, this monoblock amplifier offers impressive power reserves while maintaining a space-saving design.

High-quality Class-D MOSFET technology, carefully selected components, and a stabilized power supply ensure efficient power amplification and precise bass reproduction. The robust aluminum housing facilitates reliable heat dissipation and underscores STEG's commitment to high quality.

Thanks to its built-in high-level input with automatic power-on function, the DST1000DII can also be integrated into vehicles equipped with factory-installed car stereos. The dual-differential input system with G.R.I.P.S. technology reduces interference with the audio signal.

An adjustable low-pass filter, a subsonic filter, and a bass boost are available for customizing the sound to match the connected subwoofer. The external bass remote control allows you to conveniently adjust the bass level from the driver's seat.
