Play loud, run cool! The more energy made available to your speakers, the better they will sound. And the Kenwood eXcelon KAC-X201T amp converts energy with big-time efficiency, so it draws less current from your car's electrical system than most amps. The PowerSlide door helps eliminate heat buildup by pulling in cool air through side vents and exhausting hot air through the top-mounted fan. Kenwood's new Bass Management System lets you select a bass frequency and adjust its level of enhancement to match your car's acoustic environment. And you can control both features from a compatible Kenwood eXcelon receiver.
