Installation Guide
Safety Precautions
- Always disconnect the vehicle's negative battery terminal before performing any electrical work to prevent short circuits and damage.
- Ensure all connections are secure and properly insulated to avoid electrical hazards.
- Consult a professional car audio installer if you are unsure about any installation steps.
Mounting the XMICROLOC4
Choose a secure, dry location within the vehicle, such as under the dashboard, behind the stereo, or in the trunk. Ensure the location is away from direct heat sources and allows for adequate ventilation. The compact design of the XMICROLOC4 facilitates installation in tight spaces.
Wiring Connections
- Speaker Level Inputs: Connect the speaker wires from your factory stereo's speaker outputs to the corresponding input terminals on the XMICROLOC4's wiring harness. Ensure correct polarity (positive to positive, negative to negative) for each channel (Front Left, Front Right, Rear Left, Rear Right). Refer to your vehicle's wiring diagram for speaker wire identification.
- RCA Outputs: Connect RCA cables from the XMICROLOC4's RCA output jacks to the input jacks of your aftermarket amplifier. Match the front outputs of the XMICROLOC4 to the front inputs of the amplifier, and the rear outputs to the rear inputs.
- Remote Turn-On: Connect the blue 12-volt remote output wire from the XMICROLOC4's harness to the remote turn-on input terminal of your amplifier. This connection will automatically activate your amplifier when the factory stereo is turned on.
- Ground Connection: Connect the black ground wire from the XMICROLOC4's harness to a clean, unpainted metal surface on the vehicle chassis. A solid ground connection is crucial for optimal performance and to prevent noise.
Operating Instructions
Gain Adjustment
The NVX XMICROLOC4 features individual adjustable outputs for each channel, allowing for precise control over the audio signal level. After completing the installation and reconnecting the vehicle's battery:
- Turn on your factory stereo and aftermarket amplifier.
- Set the volume on your factory stereo to approximately 75% of its maximum level.
- Using a small flat-head screwdriver, slowly adjust the gain controls on the top of the XMICROLOC4 (labeled 'L' and 'R' for each channel pair). Start with the lowest gain setting and gradually increase it until the desired output level is achieved without any audible distortion.
- The 6:1 step-down ratio helps manage signal levels effectively, ensuring a clean signal to your amplifier. Adjust the amplifier's gain settings as needed after setting the XMICROLOC4's gains.
