Audiobank AB2000.2 2-Channel Class A/B Car Amplifier

The Audiobank AB2000.2 is a two-channel Class A/B car audio amplifier for adding dedicated external amplification to a compatible 12-volt vehicle sound system. It can power a pair of speakers in stereo or support a bridged installation when wired according to the amplifier's terminal markings. Its 2-ohm stereo capability gives installers flexibility when matching compatible speakers.

This amplifier is suited to aftermarket audio systems that need more adjustment capability than a receiver's built-in amplifier provides. Variable high-pass and low-pass crossovers help direct suitable frequencies to full-range speakers or subwoofers. A flat crossover setting is also provided when filtering is handled elsewhere in the system.

Audiobank rates the AB2000.2 at 3,500 watts maximum, with maximum ratings of 1,750 watts per channel at 2 ohms and 875 watts per channel at 4 ohms, both at 1% THD. These are maximum-power ratings rather than RMS ratings. Match speakers and wiring based on verified continuous-power and impedance requirements.

The onboard gain, crossover, and bass-boost controls allow the amplifier to be tailored to the connected speakers and source unit. A remote bass-level control knob is included for convenient adjustment from the cabin. The frequency response is specified from 10 Hz to 30 kHz, supporting both bass-focused and full-range system roles.

Line-level and speaker-level inputs support installation with head units that have RCA preamp outputs or speaker-wire outputs. Power and protection LEDs provide operating-status indication, while overload, thermal, and short-circuit protection are specified for system protection. Soft-start and muting circuitry are also listed to manage power-up and power-down behavior.

Key Features

• Two-Channel Class A/B Design: Powers left and right speakers independently in stereo operation.
• 2-Ohm Stereo Stability: Supports compatible speaker loads down to 2 ohms per channel.
• Variable Crossovers: HPF and LPF controls help match output to speakers or subwoofers.
• Remote Bass Knob: Included control allows convenient bass-level adjustment from the cabin.
• Line And Speaker Inputs: Accommodates RCA preamp signals or speaker-level source outputs.
• Protection And Status LEDs: Provides power/protection indication and specified fault protection.

Design & Installation

The AB2000.2 uses chrome-plated RCA, power, and speaker terminals for its primary connections. Its chassis measures 10.5 inches wide, 2.19 inches high, and 15.04 inches deep. The amplifier also includes power and protection indicators, along with soft-start and muting circuitry.

Mount the amplifier securely in a dry, ventilated location and connect it only to a 12-volt negative-ground vehicle electrical system. Use correctly sized power, ground, remote-turn-on, signal, and speaker wiring, with an inline fuse installed close to the battery. In stereo operation, maintain a speaker load of 2 ohms or higher per channel; verify terminal markings and compatible load requirements before bridging channels.
