Crunch GTX2250.1D

The Crunch GTX2250.1D from the GRAVITY GTX series is a high-performance digital mono amplifier designed specifically to drive powerful subwoofer systems. Despite its very compact dimensions, the amplifier delivers up to 1,125 watts RMS into 1 ohm, making it ideal for performance-oriented car audio installations with limited space.

Thanks to efficient Class D technology, the GTX2250.1D combines high output power with a space-saving design. An adjustable low-pass filter, a subsonic filter, and a bass boost are available for tuning the connected subwoofer. The included bass level remote control allows you to conveniently adjust the subwoofer level from the driver’s seat.

In addition to standard RCA inputs, the amplifier features high-level inputs with EPS® (Error Protection System). This makes it easier to integrate the GTX2250.1D into vehicles equipped with factory-installed radios or OEM sound systems. When using the high-level input, an automatic power-on function is also available.

Visually, Crunch features a high-quality aluminum heat sink and a two-tone illuminated logo panel on the top.
