Crunch GP-2000.2 2-Channel Car Amplifier

The Crunch GP-2000.2 is a two-channel Class A/B car audio amplifier for adding external power to a vehicle sound system. It is designed to run a pair of speakers in stereo or a compatible subwoofer setup in bridged mono. Its selectable crossover and level controls help tailor the amplifier to the speakers being used.

This amplifier suits listeners upgrading beyond head-unit power and installers building a straightforward speaker or subwoofer system. It accepts both low-level RCA and high-level speaker inputs, making it usable with many aftermarket or factory source units. A 2-ohm stereo minimum impedance and 4-ohm bridged minimum impedance provide practical wiring options.

The GP-2000.2 is rated for up to 1,000 watts per channel at 2 ohms, 500 watts per channel at 4 ohms, or 2,000 watts peak in 4-ohm bridged mono. These are manufacturer peak-power ratings rather than RMS ratings. Its Class A/B design and low-noise preamplifier circuit are intended for full-range or subwoofer amplification applications.

Its built-in Versa-Cross electronic crossover offers full-range, high-pass, and low-pass operating modes with a 12 dB-per-octave slope. Variable high-pass and low-pass controls span 40 to 400 Hz, helping separate bass from midrange and high-frequency duties. A selectable 0, 6, or 12 dB bass boost provides an additional low-frequency adjustment.

The amplifier uses a high-energy PWM power supply, SPEED-FET MOSFET components, and an aluminum heat sink with Quick Thermal Dispersion technology. Power and protection indicators provide basic operating-status feedback, while overload and speaker-short protection help identify fault conditions. It is a compact option for an amplified two-speaker system or a bridged subwoofer installation with appropriate impedance matching.

Key Features

• Two-Channel Class A/B Design: Powers stereo speakers or a bridged mono load.
• 2-Ohm Stereo Stability: Supports compatible 2-ohm loads on each channel.
• 4-Ohm Bridged Operation: Combines both channels for a mono subwoofer setup.
• Variable Versa-Cross Crossover: Select high-pass, low-pass, or full-range operation.
• High- and Low-Level Inputs: Works with speaker-level or RCA source signals.
• Selectable Bass Boost: Offers 0, 6, and 12 dB settings.

Design & Installation

The GP-2000.2 uses an aluminum heat sink, nickel-plated brass connection terminals, and screw-down connectors. Its internal design includes a PWM power supply, SPEED-FET MOSFET components, and thermal-dispersion engineering. LED power and protection indicators are located on the amplifier for system-status monitoring.

Mount the amplifier securely in a dry, ventilated location and do not mount it upside down. Use 4 AWG power and ground cable, connect the ground to clean bare vehicle metal near the amplifier, and fuse the positive battery cable within 18 inches of the battery. Use RCA inputs when available, or connect the high-level input harness to factory speaker outputs; match speaker impedance to the selected stereo or bridged wiring configuration.
