Crunch GP-2500.1 Low Noise Preamplifier Adult Vehicle Audio Amplifier, Black/Red, 6.1 lbs

The Crunch GP-2500.1 GROUND POUNDER mono amplifier is built to deliver high-output performance for dedicated subwoofer systems. Designed around a Class A/B topology, this amplifier combines strong power delivery with low distortion characteristics, making it well-suited for users looking to maximize bass output while maintaining sound clarity. With a maximum output of 2500 watts, it provides substantial headroom for driving subwoofers in a wide range of vehicle applications.

Equipped with SPEED-FET MOSFET output devices, the GP-2500.1 improves power efficiency while helping maintain consistent audio performance. Its high-energy Pulse Width Modulated (PWM) power supply ensures reliable power delivery with minimal strain on the vehicle’s electrical system. Thermal performance is managed by Crunch’s QTD (Quick Thermal Dispersion) aluminum heat sink, which helps keep operating temperatures stable during extended use.

For system tuning, the amplifier includes a variable 12dB per octave electronic crossover, adjustable subsonic filter (10Hz–40Hz), and phase control from 0 to 180 degrees. A built-in bass control with included wired remote allows convenient adjustment of low-frequency output from the driver’s seat, while switchable bass boost (0 / +6 / +12dB) provides additional tuning flexibility.
