Maximize your system's performance
AudioControl designed the EQX for one purpose to make your car audio system sound better. This 2-channel equalizer features 13 bands of adjustment for sonic fine tuning, along with a 2-way crossover that allows you to add a powered sub to your setup. And speaker-level inputs allow you to connect the EQX to just about any car stereo, even to factory amps up to 400 watts.
Pinpoint bass equalization
Most car audio problems occur in the bass frequencies, so the EQX gives you six bands of equalization between 31.5 and 180 Hz, along with a rolloff filter that keeps bass below the range of human hearing out of your subwoofer system. You also get seven bands of equalization at octave intervals from 250 Hz all the way up to 16,000 Hz.
The 2-way crossover offers one set of inputs, along with three sets of outputs: full range, high-pass, and low-pass. The crossover point is set at 90 Hz, but you can changer the crossover point by buying another AudioControl module, or by modifying the module installed in your EQX.
Once connected, the EQX makes it easy turn up the input gain knobs until the indicator light flickers, adjust the output knobs until the light indicates a 2-volt output, and you're all set. Balanced inputs reject noise caused by your vehicle's electrical system.
