Overview IMPORTANT SAFETY WARNING PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER, SPEAKER, OR SUBWOOFER IN A DISTORTED, CLIPPED OR OVER-POWERED MANNER CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT, POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS AND/OR VEHICLE. AMPLIFIERS REQUIRE UP TO 4 INCHES (10CM) OPEN VENTILATION. SUBWOOFERS SHOULD BE MOUNTED WITH AT LEAST 1 INCH (2.5CM) CLEARANCE BETWEEN THE FRONT OF THE SPEAKER AND ANY SURFACE.
Specifications Model: KEY200.4 RMS Power, AMP1 and AMP2 @ 14.4V, 4Ω stereo, ≤ 1% THD+N 50W x 4 Length [in, cm] 7-3/8, 18.7 Height [in, cm] 1-11/16, 4.
Installation Mounting Choose a structurally sound location to mount your KICKER amplifier. Make sure there are no items behind the area where the screws will be driven. Choose a location that allows at least 4” (10cm) of open ventilation for the amplifier. If possible, mount the amplifier in the climate-controlled passenger compartment. Drill four holes using a 7/64” (3mm) bit and use the supplied #8 screws to mount the amplifier.
Wiring Disconnect the vehicle’s battery to avoid an electrical short. Then connect the ground wire to the amplifier. Make the ground wire short, 24” (60cm) or less, and connect it to a paint-and-corrosion-free, solid, metal area of the vehicle’s chassis. Adding an additional ground wire of this same gauge (or larger) between the battery’s negative post and the vehicle chassis is recommended. Keep the audio signal cable away from factory wiring harnesses and other power wiring.
Cut the looped red power cable located in the KEY carton and install using the 20A fuse. The fuse should be within 18” (45cm) of the battery and in-line with the harness’ power cable, which is connected to your amplifier. If you ever need to remove the amplifier from the vehicle after it has been installed, the ground wire should be the last wire disconnected from the amplifier--just the opposite as when you installed it.
For multiple amplifier installations where distribution blocks are used, each amplifier should have its proper-rated fuse, or breaker, installed between the amplifier and the distribution block within eighteen inches of the block, or on the distribution block if it provides for fusing.

are speakers present. Do NOT use Radio Detect if you are using a Low-Level input signal; doing so will greatly reduce the input signal. Input Gain Control with Gain Matching: The input gain control is not a volume control. It matches the output of the source unit to the input level of the amplifier and features Gain Matching to prevent clipping the input. For a quick setup, turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25).
BI-AMP MODE: The majority of systems require this switch to be OFF. Turn ON only if your speakers are wired in “Bi-Amp” mode (refer to BI-AMP operation picture on page 9). The Bi-Amp mode is to be specifically used without passive crossovers. Possible usages are with component speakers (two woofers and two tweeters), or with door woofers and dash speakers.
LIMITER: The LIMITER may engage for multiple reasons, as indicated by the LIMITER LEDs. This is to protect your speakers and allow for continuous playback. The LIMITER will engage during: • Engine start: The KEY is a Start-Stop compatible amplifier; it will not turn off during engine start. When your vehicle’s engine is starting there is a voltage dip in the +12V line. In order to prevent a clipped output signal from reaching your speakers, the LIMITER engages during that moment.
KEY Auto Setup The KEY Activation Button is a multi-function button attached to the included microphone that will begin the Auto Setup process, toggle between Auto Setup optimized audio and the original audio once the Auto Setup process has been completed, or clear previous Auto Setup settings. The Auto Setup consists of several tune-up steps including individual speaker equalization, KICKER EQ, time delay and speaker sensitivity matching.
2. Close the car windows, turn off the engine, turn off the HVAC. Install the microphone to the top of the driver’s side headrest. Make sure the microphone faces up, pointing as straight as possible to the roof. run mic wire mic facing up headrest 3. In most cases, the Bi-Amp switch should be OFF. Check if you need to turn the Bi-Amp switch ON. Refer to page 9 for more information 4. Start the Pink Noise.
5. Begin the Auto Setup by quick-pressing the KEY Activation Button. Once initialized, you will hear repeating tones (beeps), which indicate that you must exit the vehicle and close the door. You will have 10 seconds until the process begins. Beeps and noises during the KEY Auto Setup process can be loud. For your safety, please do not remain inside the vehicle! KEY Activation Button 6. Once the Auto Setup has completed, you will hear happy music for a successful setup.
Auto Setup FAQ Q: How silent must the ambient noise be in order for the Auto Setup work properly? A: As silent as possible, both inside and outside the vehicle. The HVAC should be off and the windows rolled up, with as few obstructions in the vehicle as possible. Lower frequency noises interfere more than higher frequency noises. In case the ambient noise is too much, the Auto Setup program will quit with sad music and error code #6.
pass crossover will be applied to all speakers. This crossover is user-selectable via DIP switches with the following options: OFF, 60 Hz, 80 Hz or 120 Hz. In case of a Bi-Amp system with woofers and tweeters, the door speaker’s hi-pass is user selectable and the lo-pass is 3.2 kHz 24 dB/octave. The tweeter’s hi-pass is also 3.2 kHz 24db/octave. In case of a Bi-Amp system with door and dash woofers, the door woofer’s hi-pass is user selectable and the low-pass is 640 Hz 24 dB/octave.

Avoid physical barriers. Possible faulty speaker.
Troubleshooting If your amplifier does not appear to be working, check the obvious things first such as blown fuses, poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There are Power (PWR) & Protection (PRT) LEDs on the side panel of your KICKER KEY series amplifier. Depending on the state of the amplifier and the vehicle’s charging system, the LEDs will glow either green or red.

KICKER® KEY200.4™ 4-Channel Amplifier Quick-Start Guide | Inicio Rápido | Démarrage Rapide | Schnellstartanleitung Dear Music Enthusiast, Thank you and congratulations on your purchase of the Kicker KEY200.4 smart audio amplifier! The KEY-Series amplifier combines our time proven audio designs with state-of-the-art patented digital technology, to provide the best audio performance in a vehicle.
KEY Auto Setup: Disconnect any speakers or subwoofers not connected to the KEY amplifier, factory or aftermarket. Make sure active noise cancellation and active noise enhancement are disabled beforehand. You will need to load a source for pink noise from your head unit, whether CD, MP3, AUX, Bluetooth, USB etc. Uncompressed audio is recommended for best results, as this will ensure full amplitude across the frequency spectrum (20Hz–20kHz).
