1x Kicker 53KEY2004 KEY 4-Channel DSP Smart Amplifier, 4x50W (53KEY2004)
KEY200.4 – 200-Watt 4-Channel Amplifier with AI-Driven DSP
The KEY200.4 combines a compact 4-channel amplifier with automatic audio processing designed to improve clarity, tonality, and soundstage. Its internal processing uses an included microphone to automatically configure a 40-band equalizer, time alignment, speaker-size detection, and 24dB crossovers, while delivering 50 watts per channel at 4 ohms.
Overview
Amplification and Automatic DSP in One Compact Chassis
The KEY200.4 provides 200 watts of total power in a chassis measuring just 1-11/16 inches high, 2-3/4 inches wide, and 7-3/8 inches long. Its small footprint allows installation behind a radio, under a seat, or in a trunk.
In addition to amplification, the KEY200.4 uses an internal computer and included microphone to automatically analyze and correct the audio system. Processing includes automatic equalization, time alignment, speaker-size detection, and crossover configuration.
Power & Performance
50 Watts x 4 at 4 Ohms
- 200 watts total power (50 watts x 4 channels).
- 20Hz–20kHz frequency response, +0/-1dB.
- Signal-to-noise ratio greater than 90dB, A-weighted, referenced to rated power.
- High-level input sensitivity from 250mV to 10V.
- Bi-amp capability with defeatable operation.
Automatic Audio Processing
Microphone-Based System Correction
Press the selector and the included microphone allows the KEY200.4 to analyze the system and apply automatic processing. A 40-band equalizer adjusts tonality, while automatic time alignment and speaker-size detection help configure the system for improved soundstage and speaker performance.
Vehicle Integration
Designed for Factory and Aftermarket Systems
FIT2™ (Fail-Safe Integration Technology) provides compatibility with nearly every stock and aftermarket radio. The amplifier can turn on through either a remote 12-volt signal or DC offset and is compatible with newer vehicles using start-stop technology.
- FIT2™ integration technology included.
- Compatible with start/stop vehicle technology.
- Remote 12V or DC-offset turn-on.
- High-level input sensitivity from 250mV to 10V.
Dynamic Power Management
Automatic Peak Management
When the amplifier reaches its temperature threshold, dynamic power-management algorithms engage a limiter/compressor on musical peaks. The processing is applied for as little as milliseconds at a time while the amplifier cools, then disengages so the music returns to its full dynamic range.
- Automatic compressor functionality.
- Compressor can be defeated.
- Processing is applied to musical peaks when the temperature threshold is reached.

1x Kicker 51HS8 Hideaway Compact Powered Subwoofer Enclosure with 8-Inch Subwoofer HS8 (51HS8)
KICKER Hideaway Compact Powered Subwoofer
Overview
KICKER's legendary subwoofer technology continues to lead the way for clear-sounding, ground-pounding bass in a vehicle. It's incorporated into KICKER's latest bass machine, the brand's first compact powered subwoofer and an International Consumer Electronics Show (CES) Innovations award winner for design and engineering.
Compact Design with Powerful Performance
The KICKER Hideaway Compact Powered Subwoofer delivers surprising low-frequency output from a remarkably small enclosure, setting a new standard in plug-and-play bass performance and convenience in a vehicle. At just over three inches high and nearly 14 inches long, the Hideaway combines a 150-watt amplifier and an 8-inch subwoofer to add thumping bass to any vehicle, even from the tightest locations. It also provides a quick-connect power plug and Velcro-fastened nylon straps for secure installation and simple, fast removal.
Design and Engineering Excellence
KICKER Senior Vice President Charlie Schultz said, "Our president Steve Irby was intimately involved in the design process with the KICKER Research and Development team, and they nailed it with the Hideaway Powered Subwoofer."
"The output is amazing," said Irby during listening tests.
Advanced Features
The quick-connect Molex plug and harness entails power, signal, and remote turn-on. The Hideaway comes with a remote bass control for fine-tuning bass levels, an adjustable low-pass crossover, variable +6dB bass boost, phase-cancelling switch for maximum output, and two automatic turn-on options. It also features high- and low-level inputs for integration with nearly any factory or aftermarket head unit.
