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 51HS10 Hideaway Compact Powered Subwoofer, 10-Inch (51HS10)
Kicker 51HS10 Hideaway Compact Powered Subwoofer, 10-Inch
The Hideaway HS10 is a compact powered 10-inch subwoofer that delivers surprising low frequency impact in a tough, all-aluminum frame.
FIT PLUS - KICKER innovates once again, with FIT+™ (Fail-safe Integration Technology PLUS). Accepting input signals ranging from a mere 0.25 volt to as high as 40 volts (400 watts at 4Ω) and fully compatible with newer vehicles using start/stop systems, the HS10 works with almost any vehicle on the road today without the added expense of a line output converter.
ROCKIN’ REMOTE - The included remote control allows you to change the amount of bass without changing the radio volume, for the perfect mixture of bass in your music at any volume.
FULLY LOADED - The Hideaway comes with an adjustable low-pass crossover, variable +6dB bass boost, phase switch, and two auto turn-on options: DC-offset or signal sensing.
FANTASTIC FIT - A mere two millimeters taller than its little brother the HS8, the HS10 delivers more power and a bigger impact in an all-aluminum frame.
EASY INSTALL - The quick-connect Molex® plug and harness includes power, signal and remote turn-on. It also features high- and low-level inputs for integration with nearly any factory or aftermarket head unit, plus two automatic turn-on options for incredibly easy activation.
