Crunch GPX1600.1D

The Crunch GPX1600.1D is a compact digital monoblock amplifier designed to powerfully drive subwoofers in a vehicle. With an RMS output power of up to 800 watts into 1 ohm, this amplifier is suitable for both single high-performance subwoofers and appropriately configured multi-subwoofer systems.

Thanks to its 1-ohm stability, the GPX1600.1D can be flexibly adapted to different voice coil configurations. An adjustable low-pass filter and a subsonic filter are available for tuning the bass range. In addition, bass boost and phase can be adjusted directly on the power amplifier.

In addition to standard RCA inputs, the amplifier features a high-level input. This allows the GPX1600.1D to be installed even in vehicles whose factory radio does not have RCA preamp outputs. When using the high-level input, an automatic power-on function is also available.

A wired bass-level remote control allows you to conveniently adjust the subwoofer level from the driver's seat.
