Connecting remote wire for amp is an important step for any stereo system as it gives you access to certain features like changing songs and adjusting volume levels. While connecting remote wire for amp is relatively straightforward, it’s important to ensure you connect the remote wire correctly and in the right place to get the most from your stereo system.
The most ideal place to connect the remote wire is at the back of the head unit or radio so the amp knows when the head unit is switched on. Generally, you will see a wire with a pin connector on the back of the head unit. This is where you should connect the remote wire.
Before connecting the wire, however, it’s important to identify the right wire. The main power wire is usually either yellow or red and it should be thicker than the other wires. The remote wire is usually light blue and smaller in diameter.
If you’re connecting to a head unit with an ISO connection then you should be able to locate a dedicated remote wire on the wiring harness. For a head unit with a DIN plug, the best place to locate the remote wire is on the rear side of the unit and it is usually labeled “REM”.
Once you’ve identified the correct wire, connect the remote wire to it directly or using a connector. It’s important to ensure the connection is secure and waterproof. You can use a soldering iron to ensure the connection is watertight. After connecting the remote wire, connect the other end of the wire to the amp.
The remote wire is also sometimes referred to as a “switch wire” which is responsible for activating the amp when the head unit is switched on. It’s important to make sure the switch wire is sized appropriately and the appropriate gauge. For example, the remote wire should always be 12 gauge or thicker. If you’d like to install an aftermarket amplifier then you should use 18 gauge or higher.
Finally, when connecting the remote wire to the amplifier, make sure the polarity is correct. The red wire should be connected to positive and the black wire should be connected to negative.
If you follow these steps, you should be able to easily connect remote wire for amp and get the most out of your stereo system. However, if you’re not confident in your technical abilities, it’s still best to get assistance from an experienced technician.
