Crunch GPX3300.1D

The Crunch GPX3300.1D is a powerful digital mono amplifier designed to drive subwoofers in the car audio sector. With an RMS power output of up to 1,650 watts at 1 ohm, this monoblock amplifier offers ample power reserves for powerful bass systems and is designed for speaker impedances ranging from 1 to 8 ohms.

An adjustable low-pass filter and a subsonic filter are available for precise tuning to the subwoofer being used. In addition, bass boost and phase can be adjusted directly on the amplifier. Thanks to the master/slave function, the GPX3300.1D can also be paired with another amplifier.

In addition to standard RCA inputs, the amplifier features high-level inputs. This allows for integration even in vehicles with factory-installed radios that lack RCA outputs. When using the high-level input, an automatic power-on function is also available. The included bass-level remote control allows you to conveniently adjust the subwoofer level from the driver’s seat.
