Crunch GTX1200.2D

The Crunch GTX1200.2D from the GRAVITY GTX series combines high output power with exceptionally compact dimensions. Thanks to efficient Class D technology, this 2-channel amplifier delivers up to 2 x 300 watts RMS into 2 ohms. In bridged mode, 600 watts RMS are available at 4 ohms, making the amplifier suitable for both high-power speaker systems and driving a subwoofer.

With a width of just 135 mm and a height of 48 mm, the GTX1200.2D can be easily installed even in tight spaces. In addition to RCA inputs, the amplifier features high-level inputs with EPS and an automatic power-on function. This allows for integration into vehicles with factory-installed radios that lack standard RCA outputs.

Adjustable high-pass and low-pass filters are available to accommodate different speaker and subwoofer configurations. Both filters can also be combined to form a bandpass filter. An adjustable bass boost and the included bass level remote control allow for additional adjustment of the low-frequency range directly from the driver's seat.

The compact aluminum housing aids in heat dissipation and is visually enhanced by the two-tone illuminated logo panel on the top.
