When setting up your car sound system, it’s essential to make sure you connect all the wires correctly. And, of course, when connecting an amplifier, it’s essential to do so using the correct wire. Still, the most familiar amplifier installation issue is wire turn on remotely, which is responsible for Amplifier Turn ON/OFF. Here are four tips for connecting a remote wire to an amplifier.

What Is Remote Turn On Wire, and how does it work?

Behind the head unit, you will find a blue wire with having white stripe. It is vital to know where and how to connect the remote turn-on wire properly for your amplifier, which is very important as we wired the ground and power wires. You must remember that if you do not connect the wire properly, then there are chances that your amplifier constantly draws power ( till the battery is fully drained) or the amp will not Turn ON ( Even having good power and ground connections). So Wooster Audio will guide you if you need help determining where to connect the remote wire for an amplifier.

A remote turn-on wire is a small wire that runs from the key fob to the car’s electrical system and outputs a positive 12 volts when your car head unit is Turned ON. When you turn your car off, the remote turn-on wire sends a signal to the car’s computer telling it to turn off. If you have a keyless entry system, the remote turn on wire also sends a signal to the car’s key fob telling it to start the car and is usually located near the battery.

When the driver wants to make a turn, they will need to press a button on the remote turn on wire. The car’s turn signals will then be turned on or off, depending on the user’s preference, and it is helpful if you have to leave your car unattended for some time or if you have problems with your car’s battery.

The remote turn on wire connects the positive battery terminal to the car’s ignition coil and the negative battery terminal to the car’s ground. From the factory electrical system, the remote turn on wire receives the 12V DC signals, and then the remote turn on wire transfer these type of signals to the amplifier turn on circuit. These volts sense via the amplifier, and it turns ON; on the other hand, when there are no volts in the wire, the amplifier will remain turned off.

Do Newer Amplifiers Require a Remote Turn ON Wire?

One of the newer features that many car manufacturers are adding to their vehicles is amplifiers that don’t require a remote turn on wire. These amplifiers come with auto-turn on technology ( Signals coming from the head unit can easy sensed via RCA or speaker level inputs. If you own a car without this feature,n you have to hook up the remote turn on wire.

How do I connect Remote Wire For Amplifier - Professionally!

If your head unit does not have a remote turn on wire and you want to get your amp remotely turned ON/OFF under budget range, then the easiest way is that from the power terminal / remote turn on the terminal, you can run a jumper wire ( Not best technique!) we will not recommend you to do that, because your amplifier will continuously run till all batteries are drained but running a jumper wire (from power to remote turn on) will temporarily work and you can turn ON/OFF your amp from the head unit without any actual remote (will not solve your problem)

How To Use Toggle Switch To Remote Turn On Wire

The second way is a toggle switch (upfront), which will help you remotely turn on/off the wire. 

  • Put One wire into a power source.
  • Other wire to remote wire.

Using a Toggle switch is best to remotely turn on wire? No! The technique is not the best, and whenever you get out of your vehicle then, you always have to be sure to turn the switch Off; sometimes, when you get out of your car and forget to turn off the switch then, your amplifier will continuously run, and all battery will drain.

Tap into the fuse box

  • By taking advantage of empty slots in your car’s fuse box, you can gain access to your car’s electrical system. This is important to troubleshoot problems with your car’s electrical system. By doing this, you will be able to diagnose and fix any problems that may occur with the car’s electrical system.
  • You can use a fused slot in the fuse box so that your car will Turn-On, and then the fuse box will come alive.
  • If you’re feeling a bit overwhelmed by all of the different aspects of your car, like Tap into the fuse box, don’t worry because it can be done easily if you use the Right tools for installation. There are a few simple steps that you can take to get started.
  • The first is to access the fuse box, which is typically located under the hood or in the engine compartment, and if the fuse box is not found, then use the car’s owner’s manual. 
  • Now to start properly, take the correct idea by checking the fuse diagram
  • If you have a remote wire that you want to connect to your car, like Tesla, you can do so by connecting it to almost any fused output terminal, so make sure that the terminal only powers up when your car is running. For instance, if you have a remote wire that powers your locks, you can connect it to the “Locks” fuse box.
  • Now Use voltmeter
  • Set the voltmeter to DC
  • Now attach black test lead (To ground)
  • Now on the first hole, you have to insert a RED Test Lead pointed tip, and after that, you have to insert a RED Test Lead tip in another hole.
  • On the one hand, if the car ignition circuit is turned on and your voltmeter is reading 12 Volts, and on the other hand, if the ignition circuit is Turned Off and your volt meter is showing nothing, it means the fuse is working with the car and turn ON/Off with your car.
  • Now with that working fuse, you can hook up a remote turn-on wire, and to do that, you have to buy a “Mini fuse tap pigtail.”
  • Find switched accessory “Fuse Location.”
  • Connect the remote wire 
  • Done

Things To Know Before Buying Mini Fuse Tap Pigtail

Before you buy a Mini fuse tap pigtail, you should know a few things. 

  • First, the mini fuse tap pigtail is used to connect two power lines in a circuit. It has a female connector on one end and a male connector on the other. 
  • Second, ensure your electrical system is compatible with the mini fuse tap pigtail. 
  • As a third step, ensure that the product specs meet your requirements by carefully reading them.
  •  Last but not least, make sure you purchase a mini fuse tap pigtail from an authorized dealer to get the best product.

Hook It Up To ACC Wire

In a car, there are many different types of circuits, and some of the ones are:

  • Ignition Circuit 
  • Accessory Circuit 
  • Always-on Circuit 

Ignition Circuit

The circuit is one of the most important aspects of a car’s ignition system. This circuit ensures that the engine starts when you turn the key in the ignition. Several factors can affect this circuit, and if anyone is faulty, the engine will not start. Sometimes, this can cause problems even if you’re driving in a straight line. If you have a Tesla, your car has an advanced electronic ignition system that eliminates these problems.

Accessory Circuit

Many people install car accessories such as Bluetooth speakers, dash cams, and GPS systems. These accessories can interfere with the car’s electrical system and cause it to malfunction. It’s important to be aware of the dangers associated with installing car accessories and using a qualified professional if you need to install one.

Note: If you are trying to hook up the amplifier RTOW (Remote Turn On Wire) with Accessory Wire, then mark my words: You are trying the same concept as Tap Into Fuse Box.

Always-on Circuit

One of the features that car enthusiasts have widely praised is the car’s Always-on Circuit. This circuit ensures that your car is always ready to start. Whether driving in cold weather or during a long commute, this feature will help you save time and make your drive more comfortable.

Easiest Ways To Tap Into Electrical Wire Without Cutting Or Splicing

  • Buy “Quick Tap Connector
  • The wire should be put and tapped with a connector and a new wire.
  • Now clamp the wires.
  • The toggle switch will be needed somewhere, and you will use the switch, and the new remote wire for shutting down the amplifier when the radio is off, or the car is on.
  • Mostly some of you leave it ON, so it remains to Turn On till the car Headunit ON
  • To stop the 12 volts flow towards the remote turn-on terminal amp, you have to do the following thing: Flip the switch off.
  • A relay and accessory lead can also be used to turn on the radio by amp automatically, but not for one amplifier since the relay seems too much. Still, with multiple amplifiers, we can use the relay to connect amplifiers together.

Tap into any switched 12v power source

  • After hooking the remote turn on wire with an accessory wire; not only are you able to Turn ON/OFF amplifier automatically, also you can use a 12v switched source (Any Off), and the main example we can take of a Truck, and if you own trunk, then you can connect turn on wire to fuel pump wire.

 Use power antenna wire

  • The use of a power antenna as RTOW (Remote Turn On Wire) on your car head unit is also possible.
  • Just ensure all its modes (Aux, radio, CD, SD card) and check properly that when the head unit turns on, it comes alive or not.
  • Some cars come with a Fixed Antenna, and the power antenna wire of these vehicles only outputs 12 volts ( While the car radio is ON) So, if you are trying to connect the amplifier’s remote terminal to the power antenna wire, then note that the output from the amp is only possible when your car radio turn On.
  • Also, you cannot switch to an audio source like CD, SD card, etc., with your amplifier because of the head unit is turned off, powering the radio antenna wire.

Use a turn on module

  • The turn on module is a feature of most cars that allows small car devices to turn on signal to amp automatically.
  • There are many turn on modules that are capable of delivering a remote turn signal through a +0.8V voltage source, and their main job is to sense the speaker wire voltage and then send a +12 volt signal to the car amplifier TOC (Turn On Circuit).
  • The turn on module helps reduce the need for you to remember to turn on the car each time you drive it and can drive multiple amps, and also eliminate the turn on/off noise.

Let’s Take a Quick Overview to get your amplifier to turn on and off remotely

  1. Please disconnect the power from the amplifier by turning off the breaker or unplugging it.
  2. Locate the red wire from the amplifier’s back. This is the remote wire.
  3. Connect one end of a wire stripper to the red wire and strip away any insulation until you reach bare metal.
  4. Connect one end of a wire splicer to the bare metal and strip away any insulation until you reach bare metal again.
  5. Connect the other end of the wire stripper to one side of a switch and connect the other side to the ground terminal on your wall.
  6. Turn on power to your wall by plugging in your amplifier and turning on your switch.

What is included in a remote wire kit?

Remote wire kits are made up of various components, including the remote wire, amplifier, power supply, and connector. The remote wire is the piece of equipment that connects to the amplifier and is often small and thin, and it must be able to transmit a strong signal across a large distance.

The Amplifiers vary in size and power, but they all have one common feature: They generate lots of heat, and to avoid overheating, the remote wire kit includes a power supply. The power supply converts AC (alternating current) into DC (direct current) so that the amplifier can receive the signal from the remote wire.

Finally, the connector is used to connect the power supply to the amplifier. It has several pins that match up with specific pins on the amplifier, and when everything is connected correctly, you’ll hear sound coming from your speaker!

Disadvantages of using a remote wire kit

There are a few disadvantages to using a remote wire kit when connecting an amplifier, and the biggest one is that the wiring can be difficult to accomplish without help. Secondly, if the wire needs to be replaced, it will require someone with electrical knowledge. Finally, if the amplifier needs to be moved, the remote wire kit may not work with the new location.

What are the different types of amplifiers?

An amplifier has different types, each with its advantages and disadvantages. Class A amplifiers are the most common type and have benefits: they are relatively efficient and can produce high output levels. Class A amplifiers tend to be less expensive than class B or class D amplifiers, but they also have some drawbacks. Class A amplifiers are not as efficient as class B or class D amplifiers, and they can’t handle very high output levels.

Class B amplifiers are similar to class A amplifiers, but they have one significant advantage: they are more efficient. This means that they can produce lower output levels without sacrificing efficiency. Class B amplifiers are usually more expensive than class A amplifiers, but they have fewer drawbacks.

Class D amplifiers are the most efficient type of amplifier available. They use two semiconductor diodes to convert the input signal into an electric current and amplify it.

How do I connect a remote wire to an amplifier?

There are a few ways to connect a remote wire to an amplifier, and the best way is to use an RCA plug which is the most common way. To do this, plug one end of the remote wire into the red input on the amplifier and the other end into the black input.

What are the benefits of connecting a remote wire to an amplifier?

There are many benefits to connecting a remote wire to an amplifier; after doing this, you can more easily control the volume and tone of the music being played. Additionally, this connection can help protect your amplifier from damage caused by static electricity.

Latest amplifiers & Remote Turn On Wire

To operate the amplifier, the turn-on wire must be located remotely, which means that the factory wiring that came with the car cannot be used. Installing the additional wire kit yourself will require the purchase and installation of an additional wire kit. The feature is convenient for those looking to upgrade their car audio without dealing with a lot of hassle. However, there may be better choices for some.

What if my car stereo doesn’t have a remote wire output?

If your car stereo doesn’t have a remote wire output, you can face difficulties attaching additional components like amplifiers. In such circumstances, you could try employing alternative methods such as locating a switched power source or installing a remote turn-on adaptor to activate the amplifier’s power. Professional installation could be advantageous.
