Kicker

4-Channel Amplifier with Automatic DSP and Built-In EQ/Processor, 50-Watts RMS @ 4-Ohms x 4ch Kicker KEY series amplifiers use a powerful internal computer to deliver dramatic improvements in realism and soundstage. A massive 40-band equalizer improves tonality, and a 24dB crossover re-defines the capabilities of each speaker. The KEY200.4 delivers 200 watts RMS of power to your speakers. Measuring less than eight inches long and only two inches high, the KEY200.4 fits nearly anywhere. Mount it behind your radio, under the seat, or in your trunk with ease.  If the temperature reaches the threshold, the Kicker KEY200.4's dynamic power-management algorithms kick into gear! Instead of hearing the amplifier's volume “pumping” or blowing a fuse – KEY technology engages a nearly inaudible limiter/compressor, applied only to the peaks of the music for as little as milliseconds at a time. The amplifier quickly cools, which deactivates the compressor. Music returns to its full dynamic range without a moment’s interruption!
