Good EQ makes it sound amazing
Kicker's KQ30 30-band equalizer will help make your music sound awesome in your car. Let's face it, your vehicle's interior is not the best place for listening. The limited and uneven space, echo-producing windows, and loud road noise combine to create "hot spots" that hurt your ears and dead zones where notes disappear. The only way you're going to achieve high fidelity in your car is to use equalization to correct for all the frequency peaks and valleys that are normally present. And 30 bands of control mean you can get it sounding right whatever the conditions are like inside your vehicle.
Fine tuning for the best sound possible
Input gain controls match the KQ30's input to your receiver's output while output gain controls match the KQ30's output to your crossover or amplifier. Both adjustments feature clip lights that indicate the maximum signal level, so you can be sure all your music will always play clean and distortion-free. You can cut or boost each 1/3-octave-wide band up to 12 dB, so you can make some very powerful adjustments in order to tame even the wildest-sounding system.
