Kicker 47KEY2004 Compact Amp with Auto DSP
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. The Kicker KEY2004 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 — way more than twice the power of a typical aftermarket receiver, three or four times the power of typical factory radio.
The Kicker 47KEY2004 is so tiny, it’ll fit almost anywhere in almost any vehicle.
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 Setup software automatically sets the crossovers, 40-band EQ, and time-aligns the sound for the front seat driver. Then later, with the button, you can A/B the before- and after-processing sound, to amaze your friends and family.
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 Kicker KEY2004 prevents these issues by automatically engaging its limiter in these circumstances.
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.
