Audiotek AT-5000S 2-Channel Car Amplifier

The Audiotek AT-5000S is a 2-channel car audio amplifier designed to add external amplification to speakers or compatible subwoofer setups. It is intended for systems that need more output capability than a head unit’s built-in amplifier can provide. The amplifier is rated for up to 5000 watts of stated maximum power and supports 2-ohm-stable operation. Its full-range design allows it to be considered for speaker-focused or bass-focused installations.

This Class A-B amplifier is bridgeable, providing installation flexibility for users building a two-channel stereo system or a bridged single-channel configuration. It is also listed as tri-mode capable, which can support mixed speaker and subwoofer arrangements when the system is designed correctly. Matching speaker impedance and power handling remains important for a safe installation. The AT-5000S is suited to aftermarket car audio systems using an external amplifier rack or dedicated mounting location.

The AT-5000S uses a MOSFET pulse-width-modulated power supply to manage power conversion within the amplifier. A continuously variable input gain control helps match the amplifier to the output level of the connected source unit. It also includes a continuously variable low-pass crossover control and bass boost adjustment listed from 0 to +18 dB. These controls give the installer tools to tailor the amplifier’s role in the overall system.

For signal connection, the amplifier provides nickel-plated RCA inputs and speaker-level inputs. This gives installers options when connecting an aftermarket receiver or a factory-style source that requires speaker-level signal integration. A remote turn-on/turn-off circuit supports switched operation with the vehicle audio system. Remote subwoofer control is also included for convenient adjustment of bass level from the cabin.

The chassis uses a heavy-duty aluminum alloy heat sink to help dissipate heat during operation. Thermal and speaker-short protection circuitry are included to help protect the amplifier and connected system when a fault condition occurs. LED power and protection indicators provide at-a-glance operating status. For a complete installation, the amplifier requires properly sized power, ground, remote-turn-on, signal, speaker, and fuse-protected battery wiring.

Key Features

• 2-Channel Design: Supports stereo speaker systems or a bridged amplifier configuration.
• 2-Ohm Stability: Designed to operate with 2-ohm speaker loads per channel.
• Class A-B Operation: Provides a conventional full-range amplifier platform for aftermarket systems.
• MOSFET PWM Power Supply: Manages internal power conversion for amplifier operation.
• Remote Bass Control: Lets the user adjust bass output from the listening position.
• Protection Indicators: LED status lights show power and protection conditions.

Design & Installation

The AT-5000S has an aluminum alloy heat-sink chassis with end-panel power and speaker terminals. Its design includes dedicated connections for battery power, ground, remote turn-on, stereo speaker outputs, RCA-level input, and speaker-level input. The external heat sink and integrated protection circuitry are intended to support dependable use in an automotive environment.

Mount the amplifier on a secure, well-ventilated surface away from moisture and direct heat sources. Use a properly fused power cable at the battery, a short solid ground connection to bare vehicle metal, and wiring sized appropriately for the installation. Configure gain, crossover, bass boost, speaker impedance, and bridging only after confirming compatibility with the connected speakers or subwoofers.
