Crunch GPX2200.1D

The Crunch GPX2200.1D is a powerful digital monoblock amplifier designed to drive subwoofers in a car audio system. With an RMS power output of up to 1,100 watts at 1 ohm, the amplifier provides ample power reserves for powerful bass systems and, thanks to its 1-ohm stability, can be flexibly combined with various subwoofer configurations.

The Class D circuitry enables efficient power delivery in a compact design. An adjustable low-pass filter, a subsonic filter, and a bass boost are available for tuning the subwoofer. In addition, the phase can be continuously adjusted between 0 and 180°.

In addition to RCA inputs, the GPX2200.1D also features high-level inputs. This allows the power amplifier to be used not only with aftermarket radios but also in many systems equipped with factory-installed radios. The automatic power-on function simplifies integration into OEM systems.

Master/slave operation is also available for larger bass setups. The slave input and master output allow compatible amplifiers to be connected to each other. The system also includes a bass level remote control for conveniently adjusting the subwoofer level from the driver's seat.
