STEG DST850DII

The STEG DST850DII is a compact and powerful 1-channel Class-D mono amplifier designed specifically for the powerful and precise drive of subwoofers. With up to 600 watts RMS at 2 ohms, it offers high power reserves in a particularly space-saving design.

The high-quality MOSFET technology, the regulated power supply, and carefully selected components ensure efficient power delivery and controlled bass reproduction. Thanks to the built-in high-level input with automatic power-on function, the amplifier can also be easily integrated into vehicles with factory-installed audio systems.

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