Amp Not Turning on Remote Wire [Solved]

When you’re passionate about car audio systems, there’s nothing more frustrating than encountering issues with your amplifier. One common problem that many enthusiasts face is their amplifier not turning on due to remote wire issues.

In this guide, we will talk about the reasons behind this problem, the importance of the remote wire, and effective ways to troubleshoot and fix the issue.

Amp Not Turning on Remote Wire

Understanding the Remote Wire:

The remote wire, commonly identified as the “remote turn-on,” holds a pivotal role in the operation of your car’s audio system. It functions as the signal that instructs the amplifier to activate when you initiate your vehicle. In the absence of a well-functioning remote wire, your amplifier will not receive the directive to power on, resulting in a muted car audio system.

Why Isn’t Your AMP Turning On?

Several factors could contribute to your amplifier not turning on, and many of them are related to issues with the remote wire. Let’s explore some common reasons:

1. Faulty Remote Wire Connection:

  • Loose or disconnected wires can disrupt the flow of the signal from the head unit to the amplifier.
  • Check the remote wire connection at both the head unit and the amplifier, ensuring a secure and snug fit.

2. Defective Remote Wire:

  • Over time, remote wires can wear out, leading to breaks or internal damage.
  • Inspect the entire length of the remote wire for any visible damage, and consider replacing it if necessary.

3. Incorrect Wiring Configuration:

  • Ensure that you’ve connected the remote wire to the correct terminal on both the head unit and the amplifier.
  • Refer to the user manuals of your head unit and amplifier to verify the correct wiring configuration.

4. Issues with the Head Unit:

  • A malfunctioning head unit may not send the proper signal to the remote wire.
  • Test the head unit by checking other functions or using a multimeter to verify the output from the remote wire connection.

5. Blown Fuse:

  • A blown fuse in the amplifier or head unit could interrupt the flow of power to the remote wire.
  • Inspect and replace any blown fuses, ensuring they match the recommended amperage for your audio system.

How to Fix Amp Not Turning on Remote Wire:

Now that we’ve identified potential reasons for the remote wire issue, let’s explore effective ways to fix the problem.

1. Reconnect and Secure Wires:

  • Carefully inspect both ends of the remote wire for any loose or disconnected connections.
  • Reconnect the wires, ensuring a snug fit, and use crimp connectors or soldering for added security.

2. Replace the Remote Wire:

  • If the remote wire shows signs of damage or wear, it’s advisable to replace it.
  • Choose a high-quality replacement wire with the appropriate gauge for your system.

3. Verify Wiring Configuration:

  • Double-check the wiring configuration using the user manuals of your head unit and amplifier.
  • Ensure that the remote wire is connected to the correct terminals on both devices.

4. Test the Head Unit:

  • Use a multimeter to test the output from the remote wire connection on the head unit.
  • If there’s no signal, troubleshoot the head unit or consider consulting a professional.

5. Check and Replace Fuses:

  • Inspect the fuses in both the head unit and the amplifier for any signs of damage.
  • Replace blown fuses with ones that match the recommended amperage.

Troubleshooting Table:

For a quick reference, here’s a troubleshooting table summarizing the steps and solutions discussed above:

IssuePossible Solution
Loose or Disconnected WiresReconnect and secure the remote wire connections.
Defective Remote WireReplace the remote wire with a high-quality replacement.
Incorrect Wiring ConfigurationVerify the correct wiring configuration using manuals.
Issues with the Head UnitTest the head unit using a multimeter; consult professionals if needed.
Blown FuseInspect and replace blown fuses with the correct amperage.


To sum up, a malfunctioning remote wire can greatly impede your ability to enjoy your car’s audio system. By grasping the causes behind your amplifier’s failure to power on and adhering to the troubleshooting steps provided in this guide, you can effectively identify and rectify the problem.

Keep in mind that maintaining a well-connected and properly functioning remote wire is essential for unlocking the optimal potential of your car audio experience. Hopefully, you get the answer to “Why is Amp Not Turning on Remote Wire?”

FAQs –

Q: Does the remote wire turn on the amp?
