Crunch GTX3000.1D

The Crunch GTX3000.1D from the GRAVITY GTX series is a high-performance digital monoblock amplifier designed for demanding subwoofer systems. Despite its very compact dimensions, the amplifier delivers an RMS power output of up to 1,500 watts at 1 ohm, making it suitable even for high-power bass setups.

The modern Class D circuitry delivers high output power in a compact design. With a height of just 48 mm and a width of 135 mm, the GTX3000.1D can be installed even in spaces where there is little room for traditional high-power amplifiers.

An adjustable low-pass filter, a subsonic filter, and a bass boost are available for precise tuning to the subwoofer being used. In addition to RCA inputs, the amplifier features high-level inputs with EPS® (Error Protection System) and an automatic power-on function. This allows for integration into vehicles equipped with factory-installed radios or OEM sound systems.

A wired bass-level remote control allows you to conveniently adjust the subwoofer level from the driver's seat. The power amplifier's design is complemented by the two-tone illuminated logo panel and the high-quality aluminum heat sink.
