About: Kicker 47KEY2004 4-Channel Car Amplifier with Automatic Tuning 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. 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 — way more more than twice the power of a typical aftermarket receiver, three or four times the power of a typical factory radio.

Little Amp. Big Difference.
Measuring less than eight inches long and only two inches high, KEY amps fit nearly anywhere. Mount them behind your radio, under the seat, or in your trunk with ease.
Ready for Your Ride
KEY amplifiers are fully compatible with nearly every stock and aftermarket radio on the road today, including newer vehicles equipped with start-stop systems.
