More about the product
The Kicker 47KEY2004 is a compact 4-channel amplifier designed to deliver clean, powerful sound while simplifying the tuning process. This model is part of Kicker’s KEY series, which focuses on smart technology and space-saving design. Despite its small size, the 47KEY2004 produces 200 watts RMS, making it ideal for upgrading factory audio systems without taking up much room.
One of its standout features is the built-in Auto EQ, which automatically tunes the system for optimal sound quality. This technology corrects factory speaker limitations and improves clarity across all frequencies. The process is quick and requires minimal effort, making it perfect for those who want professional-level tuning without complex manual adjustments.
The amplifier includes a start/stop system-compatible design, ensuring reliable performance in modern vehicles. It offers two turn-on options: via a remote 12-volt signal or DC offset detection. This makes integration with factory or aftermarket systems straightforward and eliminates unnecessary complexity. Low-level RCA inputs are also available for aftermarket setups, while high-level inputs allow easy connection to factory head units.
The 47KEY2004 is engineered for flexibility in installation. Its compact chassis fits easily behind dashboards or under seats, making it suitable for vehicles with limited space. The design focuses on convenience and efficiency, ensuring that even tight installations can benefit from improved audio performance.
While the amplifier excels at improving clarity and balance, it is not intended for extreme power setups or driving large subwoofers. It is best suited for enhancing factory speakers or powering quality aftermarket speakers for a clean, detailed sound. This makes it an excellent choice for those who want better audio without adding bulky equipment or complex wiring.
