Car audio EQ tuning frequency division amplifier with six-channel output, including four amplifier channels and two subwoofer channels, featuring seven-band EQ adjustment from 63Hz to 12kHz for precise audio tuning with DC 12V power input in black
EQ5 Black Car Audio Equaliser with Six-Channel Output and Seven-Band Frequency Control

Take command of your vehicle's sound system with this dedicated car audio equaliser, engineered to provide precise signal processing between your source unit and power amplifier. The unit accepts audio through two input modes and delivers a six-channel output configuration, including four amplifier channels and two dedicated subwoofer channels. This allows for balanced distribution across a complete speaker setup while maintaining individual control over bass elements. The centrepiece of the unit is its seven-band equaliser, operating across a frequency range from 63Hz to 12kHz, enabling detailed adjustments to the audio signal before amplification for a tailored listening experience that matches both your equipment and personal preference.
Features and Construction

This signal processor is built around core functionalities essential for advanced car audio tuning. Its compact form factor, measuring 18.5cm in width, 12cm in depth, and 2.8cm in height, is designed for practical integration into various vehicle installations. The unit weighs 522g, contributing to a solid yet manageable build suitable for mounting in dashboards, consoles, or boot compartments where space is often limited.
Material and Build
The unit is constructed from standard electronic components and circuitry housed within a chassis designed for the automotive environment. All internal processing and amplification circuits are engineered specifically for operation on a DC 12V power supply, ensuring direct compatibility with a vehicle's electrical system without requiring additional voltage converters. The front panel features the necessary controls and connections, laid out for straightforward access during installation and subsequent adjustments.
Size and Practical Fit
The compact dimensions of 18.5cm × 12cm × 2.8cm allow for flexible placement within a vehicle's interior. This size is particularly suited for integration behind dashboards, within centre consoles, or under seats, where space is often constrained. The 522g weight indicates a build that incorporates necessary electronic components without being overly bulky, making it manageable to secure in position using standard mounting methods during the installation process.
Uses and Placement

This equaliser serves as a critical control point in a car audio system, bridging the gap between source units and power amplifiers. Its primary function is to process the audio signal, allowing for customisation of the sound profile before it is sent to the speakers. This is particularly valuable in vehicles where cabin acoustics can vary significantly, and factory sound systems often lack detailed adjustment capabilities.
Event or Professional Use
For enthusiasts or installers building a custom car audio system, this unit provides the tuning flexibility often required for competition setups or high-end installations. The ability to individually control the two subwoofer channels from the panel allows for precise bass management, which is crucial for achieving balanced sound in different vehicle types. The seven-band equaliser, covering 63Hz to 12kHz, offers the granular control needed to compensate for specific acoustic challenges or to shape the sound signature for particular music genres during demonstrations or shows.
Everyday Home Use
For the everyday listener seeking improved sound quality, this equaliser offers a straightforward upgrade path. It allows users to correct for the inherent acoustic limitations of a car interior, such as excessive bass resonance or lack of high-end clarity. By connecting between a head unit and amplifier, it enables adjustments that can make factory speakers sound more detailed or help aftermarket components perform to their potential, all through accessible front-panel controls for volume and frequency adjustments.
Benefits and Buying Value

The value of this signal processor lies in its specific functional design and the control it grants over a car audio system. It is not a generic amplifier but a dedicated tuning device that addresses common shortcomings in vehicle audio setups. Its design focuses on providing measurable adjustment parameters within a compact unit that integrates cleanly into existing installations.
Reuse and Low Maintenance
As a solid-state electronic device with no moving parts, the equaliser requires minimal maintenance once installed. Its operation is based on electronic signal processing, meaning it does not suffer from wear associated with mechanical components. The unit's compatibility with the standard 12V DC automotive power supply ensures it can function reliably as long as the vehicle's electrical system is operating correctly, providing lasting utility across the lifespan of the audio installation.
Why Choose This Product
This equaliser is suited for users who have identified a need for more control over their car's audio output than their source unit or amplifier provides alone. Its six-channel output structure, including dedicated subwoofer channels, supports complex system layouts. The seven-band EQ offers a practical level of adjustment for most listening scenarios without being overly complex. For those building a system piece by piece, it represents a logical addition after installing a power amplifier, serving as the control centre for fine-tuning the final sound to match both the equipment and the listening environment.
