Audiobank P5000.1D Monoblock Car Amplifier 5000 Watts Max

The Audiobank P5000.1D is a monoblock car amplifier package designed to add dedicated low-frequency amplification to a vehicle audio system. It combines the amplifier with a 4-gauge installation kit, helping provide the core wiring components needed for an amplifier-and-subwoofer upgrade. Its single-channel configuration is intended for subwoofer applications rather than full-range speaker amplification.

This package suits installers and vehicle owners building a bass-focused system in a car, truck, motorcycle, RV, or ATV. Line-level and speaker-level inputs support connection to a variety of source units, including systems that do not provide RCA preamp outputs. A variable input gain control helps match amplifier input sensitivity to the connected audio source.

The P5000.1D is specified with a 17 Hz to 180 Hz frequency response, allowing it to concentrate on low-frequency playback. Its continuously variable 40-180 Hz low-pass crossover lets the subwoofer range be blended with the vehicle's main speakers. Variable bass boost from 0 to +12 dB provides an additional adjustment for low-frequency response.

A heavy-duty aluminum-alloy heatsink is used to manage operating heat, while thermal and speaker-short protection circuitry helps safeguard the amplifier and connected system. LED power and protection indicators provide at-a-glance operating-status feedback. The package also includes a remote subwoofer level control for convenient adjustment from the listening position.

For system planning, the amplifier is listed as 2/4-ohm stable and as having a 5,000-watt maximum output rating, with 5,000W x 1 stated at 1 ohm as a maximum-power figure. The included 4-gauge kit supplies power, ground, signal, turn-on, and speaker wiring components. Proper final-load wiring, secure grounding, fuse placement, and adequate ventilation remain important for a reliable installation.

Key Features

• Monoblock Configuration: Provides one amplified channel for a dedicated subwoofer system.
• Variable Low-Pass Crossover: Adjusts from 40 to 180 Hz to help blend bass with main speakers.
• Remote Subwoofer Level Control: Lets the bass level be adjusted without reaching the amplifier.
• Line And Speaker-Level Inputs: Supports connection to aftermarket or factory-style source systems.
• Protection Circuitry: Thermal and speaker-short protection helps monitor demanding operating conditions.

Design & Installation

The P5000.1D uses Class A/B operation and a heavy-duty aluminum-alloy heatsink. Its control set includes variable gain, low-pass crossover, bass boost, and connections for line-level, speaker-level, and remote subwoofer-control use. Power and protection LEDs provide visible status indication.

Mount the amplifier on a secure surface with airflow around the heatsink, away from moisture and excessive heat. Use the included 17-foot 4-gauge power cable and 3-foot 4-gauge ground cable with a clean, bare-metal chassis ground; install the included AGU fuse holder near the battery. Confirm the subwoofer system's final impedance before wiring, and use the low-pass, gain, and bass-boost controls conservatively during setup.
