Connecting the remote wire for your amplifier is a crucial step in setting up your car audio system. This wire signals the amplifier to turn on and off in sync with your car's stereo, preventing battery drain when the system is not in use. Here’s a detailed guide on where to connect this wire, ensuring optimal performance for your audio setup.

Understanding the Remote Wire

The remote wire, often blue or blue with a white stripe, is designed to provide a 12V signal from the head unit (stereo) to the amplifier. When the stereo is powered on, this wire sends a signal that activates the amplifier, allowing it to draw power and produce sound. If connected improperly, you may experience issues such as the amplifier not turning on or draining your battery.

Connecting Your Remote Wire

1. Aftermarket Stereo Connection

If you are using an aftermarket stereo, follow these steps:

  • Locate the remote turn-on wire behind your stereo. This is typically a blue or blue/white wire.
  • Use a butt connector or T-tap connector to attach a length of wire from this remote turn-on lead to the remote input terminal on your amplifier.
  • Ensure that all connections are secure and insulated with electrical tape or heat-shrink tubing.

2. Factory Stereo Connection

For those using a factory stereo without a dedicated remote wire, you have several options:

  • Ignition Wire: Connect the remote wire to the ignition circuit which powers up when you turn on the vehicle. This ensures that your amplifier turns on only when the car is running.

  • Accessory Wire: Alternatively, you can tap into the accessory wire, which powers devices like the radio but cuts off when starting the engine. Use a T-tap connector for this method as well.

3. Fuse Box Connection

If neither of the above options is available or feasible:

  • Locate your car's fuse box, usually found near the driver's seat.
  • Identify a fuse that corresponds to either the accessory or ignition circuit.
  • Use a fuse tap to connect your remote wire to this fuse. This method provides a reliable power source and helps protect your system.

4. Other Options

If you're in a pinch and cannot find suitable wires:

  • Toggle Switch: You can install a toggle switch that allows you to manually control when your amplifier turns on and off. This requires connecting your remote wire to one terminal of the switch and then connecting another wire from the other terminal to a 12V source.

Important Considerations

  • Do Not Connect Directly to Power: Avoid running a jumper wire from a power source directly to your amplifier's remote terminal; this can lead to constant power draw and potential damage.

  • Wire Gauge: Use at least 18-gauge wire for your remote connection to ensure it can handle the low current without overheating.

  • Testing Connections: After installation, reconnect your battery and test if your amplifier turns on with the stereo. If it doesn’t work, double-check all connections for secure fittings.

FAQs About Connecting Amp Remote Wire

    • What happens if I connect to the wrong wire?
      Connecting to an incorrect wire can prevent your amplifier from turning on or cause it to remain powered at all times, draining your battery.
    • Can I connect multiple amplifiers to one remote wire?
      Yes, you can daisy chain multiple amplifiers using one remote wire as they draw minimal current.
    • Is it necessary to use connectors?
      Using proper connectors ensures reliable connections and prevents issues like shorts or loose wires.

By following these guidelines, you can successfully connect the remote wire for your amplifier, ensuring that it operates efficiently with your car's audio system while protecting your vehicle's battery life.
