Description
Overview
The Crunch GP-2500.1 GROUND POUNDER mono amplifier is engineered to deliver high-output performance for subwoofer applications. Producing up to 2500 watts of maximum power, this Class A/B amplifier combines efficient SPEED-FET MOSFET technology with a robust PWM power supply to deliver strong, consistent bass with minimal distortion. Designed for flexible installation, it supports both RCA and high-level inputs and includes a wired bass remote for convenient control.
Feature Highlights
- Mono amplifier operation optimized for subwoofer systems
- Variable 12dB per octave electronic crossover for precise tuning
- Adjustable bass boost (0 / +6 / +12dB) with built-in bass control
- Subsonic filter (10Hz–40Hz) for low-frequency protection
- Phase control adjustable from 0–180 degrees
- Low-noise preamplifier circuit minimizes signal distortion
- LED protection diagnostics for overload and short circuit monitoring
Construction & Engineering
Built around Crunch’s SPEED-FET MOSFET output technology, the GP-2500.1 maximizes efficiency while maintaining sound quality. The high-energy Pulse Width Modulated power supply ensures consistent output with minimal strain on the vehicle’s electrical system. QTD (Quick Thermal Dispersion) aluminum heat sink design improves cooling performance, helping the amplifier maintain stable operation during extended listening sessions.
Durable nickel-plated brass terminals and screw-down connectors provide secure, corrosion-resistant connections for both power and speaker wiring.
Integration & Installation
The amplifier supports both RCA inputs and high-level inputs, allowing seamless integration with aftermarket and factory audio systems. A variable input sensitivity range (0.2V–9V) provides compatibility with a wide range of source units. The included wired bass remote enables convenient adjustment of bass levels from anywhere in the vehicle.
