2. Power Connections:
   • Connect the +12V terminal to a constant +12V power source from the vehicle's battery (with an inline fuse).
   • Connect the GND terminal to a clean, solid chassis ground point.
   • Connect the REM (Remote) terminal to the remote turn-on output of your head unit.
3. Audio Inputs:
   • For head units with RCA outputs, connect the head unit's RCA outputs to the MAIN IN or AUX IN (rear) of the equalizer.
   • For portable devices, use the front 3.5mm AUX input.
   • For factory head units without RCA outputs, use the HI INPUT connections.
4. Audio Outputs:
   • Connect the FRONT OUT RCA outputs to your front speaker amplifier inputs.
   • Connect the REAR OUT RCA outputs to your rear speaker amplifier inputs.
   • Connect the SUB OUT RCA outputs to your subwoofer amplifier input.
5. Initial Settings: Before powering on, set all equalizer bands to the center (flat) position. Set volume and subwoofer levels to minimum.

Operating Instructions

Once installed, follow these steps to operate your EP1800X equalizer:

1. Power On: Turn on your vehicle's ignition and head unit. The equalizer should power on automatically via the remote turn-on wire.
2. Source Selection: If using multiple inputs, ensure your head unit is set to the correct input source.
3. Volume Adjustment: Gradually increase the master volume on your head unit and then adjust the SUB LEVEL VOLUME and main volume on the equalizer to your desired listening level.
4. Equalization: Use the 7-band graphic equalizer knobs (40Hz, 125Hz, 315Hz, 750Hz, 2.2kHz, 6kHz, 16kHz) to fine-tune the audio frequencies.
   • Turn a knob clockwise to boost that frequency.
   • Turn a knob counter-clockwise to cut that frequency.
   • Experiment with different settings to achieve your preferred sound profile.
5. Fader Control: Adjust the FADER knob to balance the sound between your front and rear speakers.
6. Subwoofer Crossover: The subwoofer crossover is fixed at 30Hz to 300Hz. Adjust the SUB LEVEL VOLUME to control the bass intensity.
