Audiotek AT-7000M 7000W Class D Monoblock Amplifier

The Audiotek AT-7000M is a single-channel car audio amplifier designed for subwoofer-focused systems. Its monoblock layout concentrates amplification on the low-frequency channel, making it suited to installations that need a dedicated bass amplifier. The amplifier is listed with a 7000-watt maximum power rating and 1-ohm stable operation.

This model is intended for listeners building or upgrading a vehicle sound system with an external subwoofer stage. It accepts both RCA and speaker-level input connections, allowing it to work with many aftermarket and factory-source integration approaches. A remote subwoofer control is included for convenient adjustment of bass level from the front of the vehicle.

The AT-7000M uses Class D amplification and a MOSFET pulse-width-modulated power supply. This combination is designed for efficient operation in a compact car-audio amplifier format. A continuously variable low-pass crossover and input-gain control provide adjustment for blending the amplifier with the rest of a system.

Bass tuning controls include a selectable bass-boost range from 0 to +18 dB. These controls can help tailor low-frequency output to the subwoofer enclosure, vehicle cabin, and listener preference. Settings should be adjusted carefully to avoid overdriving connected subwoofers or the amplifier.

For system protection, the AT-7000M is listed with thermal and speaker-short protection circuitry, along with LED power and protection indicators. Its heavy-duty aluminum-alloy heat sink supports heat dissipation during operation. The amplifier can serve as the bass section of a larger system that includes a separate receiver, signal source, speakers, and properly matched subwoofers.

Key Features

• Monoblock Class D Design: Provides a dedicated single-channel platform for subwoofer amplification.
• 7000W Maximum Power: Delivers high stated peak-output capability for bass-oriented systems.
• 1-Ohm Stable Operation: Supports subwoofer wiring configurations down to a 1-ohm load.
• Remote Bass Control: Lets the driver adjust subwoofer level from the listening position.
• Variable Low-Pass Crossover: Helps limit output to frequencies appropriate for subwoofer use.
• Protection Indicators: LED status lights show power and protection operation.

Design & Installation

The AT-7000M uses a heavy-duty aluminum-alloy heat sink and a MOSFET pulse-width-modulated power supply. Nickel-plated RCA and speaker-level inputs are listed for dependable signal connections. LED power and protection indicators provide visible operating-status feedback.

Install the amplifier in a secure location with ventilation around the heat sink, and use wiring and fusing appropriate for the completed system. Connect it to a compatible source using either RCA or speaker-level inputs, then set the low-pass crossover, input gain, and bass boost conservatively during initial setup. Confirm that the final connected speaker load does not fall below the amplifier's listed 1-ohm stable rating.
