Audiobank P2004 4-Channel 2000W Bridgeable Amplifier

The Audiobank P2004 is a four-channel car audio amplifier for adding external power to compatible vehicle speaker systems. It is designed for installations where a head unit’s built-in amplification is not sufficient for the desired speaker output. Its four channels allow it to be used with a conventional front-and-rear speaker layout or in bridged configurations.

This Class AB amplifier is suited to shoppers building or upgrading a basic multi-speaker car audio system. It supports 2-ohm stereo operation and can also be bridged into two channels at a 4-ohm load. That flexibility helps accommodate different system layouts without requiring a separate amplifier for every channel pair.

The P2004 is rated at 175 watts RMS per channel at 4 ohms, with stated maximum ratings of 250 watts per channel at 4 ohms and 500 watts per channel at 2 ohms. For bridged operation, its stated maximum rating is 1,000 watts per pair at 4 ohms. Match connected speakers and wiring to the amplifier’s impedance requirements before installation.

Built-in crossover controls provide separate high-pass and low-pass adjustment ranges for tailoring the signal sent to connected speakers. A variable bass boost is also provided for systems that need additional low-frequency adjustment. The amplifier’s 20 Hz to 22 kHz frequency-response specification supports use across a broad audible range.

A MOSFET pulse-width-modulated power supply, remote turn-on/turn-off circuit, and protection circuitry support its role as a dedicated vehicle amplifier. Power and protection LEDs provide at-a-glance operating status. The compact surface-mount form factor is intended for secure installation in an appropriately ventilated location.

Key Features

• Four-Channel Design: Powers up to four speaker channels from one amplifier.
• 2-Ohm Stability: Supports compatible 2-ohm stereo speaker loads.
• Bridgeable Outputs: Configures as two bridged channels at 4 ohms.
• Variable Crossovers: Helps direct appropriate frequency ranges to connected speakers.
• MOSFET PWM Supply: Uses a pulse-width-modulated MOSFET power supply.
• Protection Indicators: LED status lights show power and protection conditions.

Design & Installation

The P2004 uses a heavy-duty aluminum-alloy heatsink and a compact 8 x 2 x 12 inch chassis. Its Class AB design includes soft turn-on behavior, nickel-plated RCA connections, and LED power/protection indication. Thermal and speaker-short protection circuitry is specified to help protect the amplifier and connected system during fault conditions.

Mount the amplifier on a stable surface with clearance for ventilation, and use it only in a 12-volt DC vehicle electrical system. Connect compatible RCA signal leads, speaker wiring, power, ground, and remote-turn-on wiring according to the installation instructions for the vehicle and amplifier. Use four-channel stereo wiring for compatible speakers, or bridge channel pairs only with 4-ohm loads.
