Where To Connect Remote Wire For Amp? | Complete Guide

Most people ask if I’m trying to add an amp to my car stereo system, but I’m not sure where to connect the remote wire. 

It can be tricky to figure out where to connect the remote wire for your amp, especially if you’re not familiar with car audio systems.

In short, to connect a remote wire for an amplifier, use your car’s fuse box, find or connect it to the ACC wire, then switch the 12v power source or the power antenna wire. Finally, you can try connecting it to a turn-on module.

This is a short answer, keep reading this helpful guide that will show you exactly where to connect remote wire for an amp. Plus, I’ve also included a few tips on how to get the most out of your new amp installation.

Why Do You Need To Connect A Remote Wire For The Amp?

Most car stereos today are equipped with an amplifier. The main job of an amplifier is to boost the signal from the head unit to the speakers. This is necessary because the head unit usually doesn’t have enough power to drive the speakers at full volume.

There are so many reasons why you would want to connect a remote wire for your amplifier. The most common reason is that you want to be able to turn on the amplifier without having to turn on the head unit. This can save a lot of battery power, which is important if you’re going to be listening to music for a long time.

Another reason why you might want to connect a remote wire is if you’re using an aftermarket head unit. Most aftermarket units don’t have amplifiers built-in, so you’ll need to add one yourself. Connecting a remote wire will allow you to turn on the amplifier without having to turn on the head unit, which can save battery power.

Finally, some people like to connect a remote wire because it makes the installation process simpler. If you’re not using an aftermarket head unit, you’ll need to connect the remote wire to the factory head unit. This can be a pain, so connecting a remote wire can save you some time and hassle.

7 Steps Where To Connect Remote Wire For An Amp?

Here are the top 7 steps to connect a remote wire for the amp:

1. Open Fuse Box And Find The ACC Wire

Most cars have a fuse box located under the hood. This is where you’ll find the ACC wire, which is the wire that you’ll need to connect the remote wire to.

To find the ACC wire, open the fuse box and look for a wire that has power only when the key is in the “on” position. This is usually a green or yellow wire. Once you’ve found this wire, use a test light or multimeter to test it for power.

2. Connect The Remote Wire To The ACC Wire

Once you’ve found the ACC wire, use a butt connector or solder to connect the remote wire to it. Make sure that the connection is secure and cannot be pulled apart easily.

3. Find A Switched 12v Power Source

The next step is to find a switched 12v power source. This is a wire that has power only when the key is in the “on” position. To find this wire, use a test light or multimeter to test for power on each wire in the fuse box. Once you’ve found a wire that has power only when the key is in the “on” position, use a butt connector or solder to connect the remote wire to it.

4. Find The Power Antenna Wire

If your car has a power antenna, you can use this wire to turn on the amplifier. To find this wire, follow the antenna wire from the head unit to the antenna. Once you’ve found the wire, use a test light or multimeter to test for power. If the wire has power, use a butt connector or solder to connect the remote wire to it.

5. Try A Turn-On Module

If you’re still having trouble finding a switched 12v power source, you can try using a turn-on module. This is a device that takes the place of the ACC wire and allows you to turn on the amplifier with a switch. To install a turn-on module, follow the instructions that come with the module.

6. Connect The Ground Wire

The final step is to connect the ground wire to the chassis of the car. This will complete the circuit and allow the amplifier to turn on. To find a good spot to connect the ground wire, use a test light or multimeter to test for power on the chassis of the car. Once you’ve found a good spot, use a butt connector or solder to connect the ground wire to it.

7. Test The Connection

Once you’ve connected all of the wires, it’s time to test the connection. Turn on the ignition and turn on the amplifier. If everything is working properly, you should hear sound coming from the speakers. If not, check all of the connections and make sure that they are secure.

Tips And Tricks

Here are some tips and tricks for connecting a remote wire to an amplifier:

  • If you’re having trouble finding a switched 12v power source, you can try using a turn-on module. This is a device that takes the place of the ACC wire and allows you to turn on the amplifier with a switch. To install a turn-on module, follow the instructions that come with the module.
  • Connecting a remote wire will allow you to turn on the amplifier without having to turn on the head unit, which can save battery power. Finally, some people like to connect a remote wire because it makes the installation process simpler.
  • If you’re not using an aftermarket head unit, you’ll need to connect the remote wire to the factory head unit. This can be a pain, so connecting a remote wire can save you some time and hassle.
