What is a remote wire, and why is it important?
The remote wire, often referred to as the “remote turn-on” wire, is a crucial component in car audio systems. It enables the amplifier to turn on and off with your vehicle’s head unit or stereo. By connecting the remote wire to the appropriate source, you can ensure that your amplifier activates when you power on your stereo, which helps to prevent battery drain and ensure optimal performance.
In most installations, the remote wire is typically connected to the head unit’s remote output terminal. This is usually a blue wire labeled as “remote” or “power antenna.” When the head unit is powered on, it sends a signal through the remote wire to the amplifier, allowing audio signals to flow. Proper installation of the remote wire thus enhances the audio system’s functionality and lifespan.
Where is the remote wire connected in a car stereo setup?
In a typical car stereo setup, the remote wire connects directly to the head unit. You will usually find a terminal on the back of the stereo labeled as “remote” or “amp turn on.” This terminal is where you would connect the remote wire originating from your amplifier. This arrangement allows your amplifier to be synchronized with the head unit’s power status.
If your head unit lacks a dedicated remote output, you can connect the remote wire to the accessory power wire. This alternative ensures that the amplifier powers on whenever the ignition is in the accessory position. However, this method may lead to insufficient turn-off time, so it’s important to consider the overall design of your audio system.
Can the remote wire be connected to other sources besides the stereo?
Yes, the remote wire can technically be connected to other sources aside from the car stereo, as long as those sources provide a switched power signal. For example, some users opt to connect the remote wire to a factory amp turn-on wire if it exists, which can be found in older vehicles that have built-in amplifiers.
However, it’s generally advisable to connect the remote wire to the head unit for reliability and consistency. Connecting to a non-standard source can lead to potential issues, including improper activation or concerns about battery drain. Always consult your vehicle’s wiring diagram and your audio components’ specifications before making an alternative connection.
What gauge wire should I use for the remote wire?
For the remote wire, a smaller gauge wire is typically sufficient since it carries a low current. A 16-gauge wire is commonly recommended for remote turn-on applications, as it provides adequate strength and flexibility for routing through the vehicle. Using a thicker wire than necessary may complicate installation, while a thinner wire could have issues carrying the current effectively.
It’s also crucial to consider the length of the remote wire run.
