Four Channel Car Amplifier with Automatic Acoustic Correction

KICKER released the KEY180.4 Smart Car Amplifier with 180 watts of power, Auto-EQ and compatibility with start/stop vehicles. The extremely compact 4×45-watt DSP car amplifier combo automatically improves the sound quality of any vehicle with the push of a button.

Using a powerful internal computer and calibration microphone, the KEY180.4 offers up dramatic improvements in realism and soundstage without the need for an external processor or RTA (real-time analyzer). Users mount the amp behind the radio or under a seat (with its compact size of two inches wide by eight inches long), then press the selector switch on the in-line microphone (placed on the headrest near where the listener’s ears would be).

What would take hours for a professional to achieve happens in a matter of seconds, all automatically with the press of a single button. The button press sets the KEY’s test tones and proprietary algorithms in motion. The system detects speaker sizing, applies a 24dB crossover and 40 channels of equalization, applies time alignment and customizes the gain levels of each channel independently. The true potential of the vehicle’s sound system is revealed in a matter of seconds, delivering dramatic improvements in realism and soundstage without the need for expensive external processors or personal tuning time.

KEY technology uses FIT2™ (Fail-Safe Integration Technology) and start/stop compatibility to work with nearly any vehicle on the road today. Once installed, the amp can be activated via remote 12v signal or DC offset. Additionally, the amplifier’s miniscule footprint allows for easy installation in a myriad of locations, from behind the radio, to under a seat, or even behind the glove box.

KEY technology also employs a unique method of controlling heat and virtually eliminating the need for a protection mode. Faced with thermal overloads, traditional amplifiers force the listener to experience volume “pumping,” even a possible shutdown, or the fuse simply blows. KICKER engineers created a dynamic system that engages a inaudible limiter/compressor applied only to the peaks of the music for as little as milliseconds at a time. The temporary drop in power results in the amplifier cooling and a cancellation of the compressor. Music then returns to its full dynamic range without a moment’s inconvenience or interruption.
