Remote Wire For Amp To Fuse Box

Connecting a remote wire for an amplifier to a fuse box is a common practice among car audio enthusiasts. This setup allows the amplifier to turn on and off in sync with the vehicle's ignition, ensuring that it only draws power when needed. The remote wire is typically a thin wire that sends a signal from the head unit (or another power source) to the amplifier, signaling it to power up or down. This guide will provide detailed steps on how to properly connect a remote wire for an amplifier to your vehicle's fuse box.

The remote wire connection is essential for ensuring that your amplifier operates correctly. If not connected properly, the amplifier may either not turn on or stay on continuously, which can drain your battery. Understanding how to tap into the correct fuse is crucial for a successful installation.

Understanding Remote Wires

The remote wire is typically colored blue or blue with a white stripe. Its primary function is to provide a signal to the amplifier, indicating when it should be powered on. When the head unit turns on, it sends a voltage through this wire, activating the amplifier. Conversely, when the head unit is off, the voltage drops, turning off the amplifier.

Using a fuse box for this connection is common, especially when working with factory head units that do not have a dedicated remote turn-on output. You can tap into any fuse that receives power only when the ignition is on. This ensures that your amplifier will not draw power when the vehicle is off, preventing battery drain.

Selecting the Right Fuse

When choosing a fuse from which to draw your remote wire connection, ensure it meets specific criteria:

• Switched Power: The fuse must only receive power when the ignition is on.
• Low Current Draw: The remote wire typically requires minimal current; thus, a small fuse (1-10 amps) is usually sufficient.
• Accessibility: The chosen fuse should be easily accessible for installation.

Common choices for fuses include those associated with accessories like power windows or radios. For example, using the radio fuse can be effective since it powers up with the ignition.

Tools and Materials Needed

Before starting your installation, gather all necessary tools and materials:

• Wire Strippers: To strip insulation from wires.
• Butt Connectors or T-Tap Connectors: For connecting wires securely.
• Electrical Tape or Heat Shrink Tubing: To insulate connections.
• Add-A-Fuse Kit: Allows you to add a circuit without cutting existing wires.
• Multimeter: To test voltage and ensure proper connections.

Step-by-Step Installation Guide

Step 1: Locate Your Fuse Box

Identify where your vehicle's fuse box is located. This can typically be found under the dashboard near the driver's side or in the engine compartment. Consult your vehicle's manual if you are unsure.

Step 2: Identify Suitable Fuses

Using your multimeter, test various fuses in your fuse box to find one that only receives power when the ignition is on. Look for fuses related to accessories like:

• Radio
• Power windows
• Cigarette lighter

Step 3: Prepare Your Remote Wire

Cut a length of wire suitable for running from your fuse box to your amplifier location. Strip both ends of this wire to prepare it for connection.

Step 4: Use an Add-A-Fuse Kit

Insert an Add-A-Fuse into the chosen slot in the fuse box:

• Remove the original fuse from its slot.
• Insert it into one side of the Add-A-Fuse.
• Connect your stripped remote wire into the other side of the Add-A-Fuse.

This setup allows you to maintain the original circuit while adding your remote wire.

Step 5: Connect to Your Amplifier

Run the other end of your remote wire back to your amplifier. Strip this end as well and connect it to the remote turn-on terminal on your amplifier using either butt connectors or soldering for a secure connection.

Step 6: Secure All Connections

Once all connections are made, use electrical tape or heat shrink tubing to insulate them thoroughly. This step is crucial for preventing shorts and ensuring long-term reliability.

Step 7: Test Your Installation

Before finalizing everything, turn on your vehicle and check if your amplifier powers up when you start your head unit. If everything works correctly, you can proceed with securing all wires and closing up any panels you may have removed during installation.

Troubleshooting Common Issues

If you encounter problems during installation or operation:

• Amplifier Does Not Turn On: Check all connections and ensure that you tapped into a switched power source.

• Amplifier Stays On Constantly: This may indicate that you tapped into a constant power source rather than a switched one.

• No Sound Output: Ensure all connections are secure and check if any fuses have blown in both your vehicle's electrical system and at the amplifier itself.

Safety Considerations

Always prioritize safety during installation:

• Disconnect the negative terminal of your battery before starting work to prevent accidental shorts.

• Use appropriate gauge wiring for both power and ground connections to avoid overheating and potential fire hazards.

FAQs About Remote Wire For Amp To Fuse Box

• What gauge wire should I use for my remote wire?
  A standard 18-gauge wire is typically sufficient for remote turn-on applications.
• Can I use any fuse slot for my remote wire?
  No, ensure you select a slot that only receives power when the ignition is on.
• What happens if my amp stays on constantly?
  This usually means you've connected it to a constant power source instead of a switched one.
• Do I need an inline fuse for my remote wire?
  It's not required but can provide extra protection against shorts.
• How do I know if my remote wire connection is working?
  Test with a multimeter; it should show voltage when the head unit is powered on.

By following these guidelines carefully, you can ensure that your amplifier operates correctly without draining your vehicle's battery when it's not in use. This setup enhances your car audio experience while maintaining safety and efficiency.
