Kicker 47KEY5001 Compact Monoblock with Auto DSP
Now you can get fantastic, powerful bass without shelling out a lot of money for a huge amp or spending too much time tuning the system after installation. The Kicker KEY5001 compact subwoofer amplifier features automatic signal processing that tailors the sound to blend in perfectly with your specific stereo system. And this compact power pack can send up to 500 watts RMS to your sub.
After installation, you download both the Key sine sweep and a test tone from Kicker. You set the amp gain using the test tone and a KEY indicator light. The KEY Auto setup with the sine sweep analyzes your system’s response and applies the equalization and bass boost necessary to produce great bass. Then later, with the KEY button, you can A/B the sound before and after processing to amaze your friends and family.
500WRMS at 1Ω from something the size of an old Nokia
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 sub. The Kicker KEY5001 prevents these issues by automatically engaging a 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 vehicle, even one a factory amplified system. The Radio-Detect feature makes sure you never get a “No Speakers Detected” message on your receiver’s display when you install the Kicker KEY5001.
