Kicker Key200.4

• Automatic high-fidelity!
• Now you can get fantastic, high-fidelity sound without shelling out a lot of money for complicated gear or spending too much time tuning the system after installation. Kicker’s KEY200.4 compact car amplifier features automatic signal processing that tailors the sound for your specific vehicle’s interior space. This 4-channel compact power pack will send 50 watts RMS to each of your front and rear speakers — more than twice the power of a typical aftermarket receiver, three or four times the power of a typical factory radio.
• KEY Auto Setup tunes in minutes, not hours!
• After installation, you set up the included calibration mic, start the test noise (downloaded from Kicker), hit the activation button, and the KEY Auto.
• A/B the before- and after-processing sound, to amaze your friends and family.
• Advanced features!
• You can manually enable Auto Compression, for a more consistent and safer power output. A limiter kicks in and lights up when it detects clipping, letting you know that something’s too loud. A Bi-Amp mode lets you actively run tweeters and woofers without a passive crossover, by applying customized active crossover settings during the KEY Auto Setup process.
• Start-Stop problem solved!
• Some eco-friendly cars actually turn off their engines when stopped, and then start up again when the brakes are released. The voltage dip during starting could shut down an amplifier or allow it to pass a dangerous clipped signal to the speakers. The KEY200.4 prevents these issues by automatically engaging its limiter in these circumstances.
• Integrates well!
• This amp’s so tiny, it’ll fit almost anywhere in almost any vehicle. Kicker’s FIT2™ technology, using speaker-level inputs with DC offset sensing turn-on, ensures this amp will work in just about any system, even one with a factory radio. The Radio-Detect switch makes sure you never get a “No Speakers Detected” message on your receiver’s display when you install this amp.
