Power antennas are another part that can be controlled with an external wire. In older vehicles, power antennas will automatically expand to retract once the radio has been off or on. The remote wire functions as a trigger, sending signals through the unit’s head to power. In the event that the head unit is turned on, the wire provides an electrical signal to the power antenna, which causes it to grow. In contrast, if it is shut off, the wire ceases to transmit the signal, and the power antenna retracts.

Activating Motorized Devices

Certain motorized gadgets in the car, like the motorized screen, flip-down screens, or enclosures for subwoofers that are motorized, require an activation wire from a remote. This wire is connected to the audio system or head unit directly to the controlling module for the motorized gadget. If the unit’s head is switched on, it transmits an electrical signal to the remote wire, instructing that the controller module start the motor and run the device. When the head unit’s power is turned off, the wire sends a signal to a control unit to shut off the motor and retract the device.

Triggering Power Distribution Units

PDUs or power distribution units (PDUs) are utilized to control and distribute the electrical power of the vehicle. PDUs are able to be fitted with inputs to remote wires, which allow the control of them remotely. When a remote wire is connected to the PDU and the head unit, a control module can be used to activate or deactivate particular power circuits. This feature is especially useful for custom car audio systems in which multiple components need controlled power distribution to ensure efficient effectiveness and performance.

Custom Applications and Installations

The range of applications for remote wires extends beyond components that are factory installed. It is a great option for custom installations and applications where an additional level of management or control is required. For instance, in sophisticated audio systems, remote wires can be used to activate multiple processors or amplifiers at the same time and ensure that they operate in synchronization.
