KEY Auto Setup tunes In Minutes, Not Hours

After installation, you set up the included calibration mic, start the test noise , 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.

 

 

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 KEY180.4 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 almost 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.
