¿Cómo conectar los altavoces del automóvil a la radio sin el arnés?

Si se pregunta si es necesario un arnés de cableado de radio para conectar sus altavoces a la unidad principal y no está seguro de qué hacer si no tiene uno, este artículo es para usted.

Hay un par de métodos que puede usar para conectar altavoces sin el arnés, y son relativamente simples.

Cuando la radio de su automóvil no tiene un arnés o cuando el arnés existente o los cables están dañados, la forma más fácil de conectar los altavoces es usando un adaptador de arnés de radio de coche . El adaptador del arnés debe enchufarse en la parte posterior de la radio y luego los altavoces deben conectarse directamente a los cables codificados por colores en su radio.

El siguiente artículo detallará cada aspecto de un arnés y parlantes, considerando todos los factores necesarios al conectarlos a su radio.

Esto incluirá qué es un arnés, ¿necesita uno?, ¿se pueden asegurar los parlantes sin un arnés?, cómo conectar los parlantes sin un arnés, varios métodos para hacerlo, especificaciones específicas del cable del estéreo del automóvil, como el color, así como el calibre del cable del altavoz. y longitud

Comprender un arnés de cableado

Cuando intente conectar los parlantes de su automóvil sin un arnés (aunque no es difícil), puede considerar uno debido a su asequibilidad y disponibilidad, incluso para sistemas de posventa como parlantes y radios.

Incluso obtiene arneses más pequeños que funcionan para servir como una mini versión separada que le permite agregar cableado adicional o hacer configuraciones si es necesario.

¿Necesito un arnés de cableado para instalar los parlantes del automóvil?

Un arnés de cableado facilita la conexión de los cables de audio del automóvil. Un arnés puede albergar hasta 15 cables (una radio de automóvil estándar) o incluso más si su automóvil alberga una unidad de infoentretenimiento DIN o doble DIN. Sería una tarea abrumadora, especialmente en el nivel de fabricación de vehículos de motor, tener que cablear los componentes a mano entre sí todo el tiempo. Por lo tanto, se creó este pequeño dispositivo que soporta todo el sistema.

Los arneses también se pueden usar para situaciones especializadas en las que los tipos de conexión simples y los conectores como los conectores de crimpado simplemente no funcionan.

Según el sistema estéreo del coche que tenga y los componentes que tenga, conectar los altavoces sin un arnés no será demasiado difícil.

Ten en cuenta que un arnés no es demasiado caro y son relativamente fáciles de encontrar, incluso si necesitas uno específico. Puede comunicarse con el fabricante de la radio de su automóvil y preguntarle quiénes son sus proveedores, y puede comunicarse con una tienda de repuestos de automóviles usados ​​e intentar encontrar uno allí.

Sin embargo, básicamente no necesita un arnés para conectar los altavoces del automóvil con la radio.

¿Son los cables de los altavoces parte del arnés de la radio del automóvil?

Los cables de los altavoces son la parte más grande de las conexiones del arnés. Un arnés de radio de automóvil estándar con 15 puntos de conexión dedicará hasta 8 puntos de conexión solo para sus altavoces.

Esto se debe a que la radio o el amplificador de su automóvil generalmente tendrá cuatro canales de dos altavoces cada uno (delantero y trasero), y cada canal debe tener una terminal positiva y una negativa.

¿Un arnés de cableado agrega alguna funcionalidad adicional?

El papel de un arnés es relativamente sencillo. Tiene que conectar eléctricamente dispositivos eléctricos y componentes eléctricos que están instalados dentro de su automóvil. Por lo tanto, se puede usar un arnés para la mayoría de los elementos de su vehículo, como el sistema de iluminación, los ventiladores, los acondicionadores de aire, la radio, etc.

Un arnés de cableado está hecho de muchos cables individuales que desempeñan funciones específicas. Estos pueden incluir el envío de energía constante, dispositivos de activación, transmisión de información o dirección remota para otros dispositivos.

¿Todos los estéreos de automóviles tienen los mismos conectores (tipos de conexión)?

Es muy probable que todos los estéreos para automóviles tengan el tipo de conexión macho y el tipo hembra que puede comprar, o de lo contrario estaría conectado a su automóvil. Además, todos los estéreos de automóviles del mercado de accesorios pueden usar el mismo arnés.

¿Cómo sé qué cables de altavoz son cuáles?

Todos los sistemas de radio y audio del automóvil ahora están codificados por colores según un estándar específico, para que sepa qué cables están en qué colores. Siempre habrá el mismo color para el mismo cable sin importar qué auto o radio esté tratando de modificar.

¿Cuál es el código de color de los cables del estéreo del automóvil?

En su mayor parte, la radio del automóvil y el arnés vendrán con ocho cables para cada altavoz, y estos son los colores en los que queremos centrarnos al conectar los altavoces:

Gris

Los cables grises se utilizan para conectar los altavoces delanteros derechos a su estéreo. El cable gris es positivo y el gris/negro es negativo.

Blanco

Los cables blancos conectan los altavoces delanteros izquierdos a la radio de su automóvil. El cable blanco es positivo y el cable blanco/negro es negativo.

Púrpura

Los cables morados conectan los altavoces traseros derechos a la radio de su automóvil. El cable morado es positivo y el cable morado/negro es negativo.

Verde

Los cables verdes conectan los altavoces traseros izquierdos a la radio de su automóvil. El cable verde es positivo y el cable verde/negro es negativo.

¿Debería cortar el arnés de cableado de la radio del automóvil?

Esto solo se aplica si tiene una radio nueva y necesita instalarla. Cuando compre una nueva radio o unidad principal para su automóvil, lo más probable es que venga con un arnés ya instalado con una conexión de tipo macho en el extremo. Este arnés probablemente tendrá una longitud bastante mayor.

Una nueva radio o unidad principal viene con un arnés tan largo porque algunos vehículos necesitan una longitud de cable más larga para llegar a la sección o secciones de su automóvil para enchufarlo.

No hay nada peor que comprar una nueva radio o unidad principal y descubrir que la longitud del cable es apenas inferior al lugar donde debe conectarse.

Sin embargo, algunos automóviles están diseñados para albergar la radio y un área más pequeña de cableado. What you should do then is cut your harness and solder it back together so you do not have to cram a large amount of wiring in the small allotted area.

The soldering process is straightforward, and you do not need to be a professional to solder one or two wires. One thing to take note of is that if your harness has fuses or noise filters on them (this could be from the constant wire), then it is advised that you cut the harness beyond these points (but only for these wires) so you can keep those components fitted as they are indeed there for a reason.

How to Wire Your Car Speakers to the Radio Without a Harness

There are several ways to connect speakers with the car stereo, and they do not need any exacting knowledge or understanding of car circuitry or audio systems in general.

What factors should you consider before you connect your speakers to the radio without a harness?

Even though connecting speakers to your car radio is a pretty straightforward task, there are a handful of things you should consider so you get the job done right the first time around.

Where is the amplifier in the head unit?

It does not matter what audio system you have or where the audio system is. All audio systems at their core use the same principle. You firstly have a sound source (in our case, the car radio). The source is the device that will send the audio signal, which is of a low level to the preamp that will convert the low-level signal into a line level.

All radios will have a preamp built into them, so you do not have to worry about that. The preamp then sends the signal to a powered amplifier, where the signal is then boosted and pushed out through your speakers.

Is it a built-in amplifier?

Depending on your car audio system setup, your standard factory OEM radio may have a built-in amplifier. This is not uncommon, and then the possibility of you being able to wire your speakers to your car radio remains.

If you have replaced your car radio with the one you have purchased, make sure it has an amplifier built into it. Otherwise, you would need the additional setup to add an external amplifier to your car audio system.

Is it an external amplifier?

If your car audio system has an external amplifier, you will not be connecting your speakers to the radio, and in this case, a harness would be unnecessary.

This is because the speakers will connect directly to the terminals in the amplifier.

Since technology is ever increasing in today’s world, car manufacturers sometimes implement external amplifiers in their standard OEM factory audio setup. Depending on how the amplifier is built and designed, you would connect the wires from your speakers to it directly.

The same for aftermarket car amplifiers. What you have to do is to connect the radio outputs (RCA outputs if it was an aftermarket radio) into your amplifier and connect your speakers to your external powered amplifier by way of speaker wires and the amplifier’s high-level terminals.

Considering Speakers That Have No Harness.

Typically speakers will not come with a harness. If they are purchased as aftermarket speakers, they probably won’t even include speaker wire unless you buy them in some bundle package.

As I just mentioned, you need to know how your audio system is installed:

• Are you replacing existing speakers that are connected to your radio?

• Are you just trying to fix the sound system of a car that you know nothing about?

These are all factors you need to consider, and with speakers, you need to know if the wire runs to an external amplifier or the radio.

The only thing you will need to purchase, if necessary, is speaker wire, and depending on where they are in your car, you would need to consider the correct length and gauge, which could be a few feet.

How to Choose Car Speaker Wires?

Suppose you need to choose your speaker wire and purchase some. In that case, a wire gauge will play a role because of your amplifier’s power and distance away from the speakers (in this case, we are assuming that you are not connecting to an amplifier but rather your radio).

One thing to note is that the higher the gauge, the thinner the wire. Usually, you can be sure that your system would need between 18 and 12 gauge wires, depending on a few factors. The 18 gauge will be the thinnest wire you would need, and the 12 gauge would be the thickest and will preferably be used for the subwoofer (this is for most standard applications).

A thick wire would be recommended for speakers with low impedance levels (2 ohms) where the wire is relatively long and the power passing through it is relatively high. Hence, consider 12 to 14 gauge wire.

A thin wire would be recommended for speakers with a higher (or standard) impedance level (4 ohms) and run in a relatively short distance. In general, when the distance is less than 50 feet, you do not have to worry about increasing the wires’ thickness.

Considering your radio that has no harness.

The radio in your car should be fitted with a harness, whether it is a standard OEM factory radio or an aftermarket radio. As we said, a harness helps connect devices of a car (a radio) to other sections of the vehicle more quickly and easily, and all modern cars and aftermarket systems have them implemented for user-friendliness.

If you purchased a car stereo without a harness, you can still connect your speakers to your car radio without a harness, and we will cover the various ways below.

What Options Do You Have When Trying to Connect Your Car Speakers to Your Radio Without a Harness?

We are now assuming that you do not have an external amplifier in your car audio setup and that the speakers will run to your radio that can power the speakers. We will then also assume that you have no harness attached to your radio for some reason. When considering these factors, there are three things you can do to connect your speakers to your car radio without a harness.

Buy a Replacement Harness for Your Car Radio.

Harnesses are relatively cheap and inexpensive. You get various sizes and shapes and can most likely find one that fits your radio model if you do not have one or yours is not working correctly.

This would make things more comfortable if you later intend to purchase a new radio. Otherwise, you would have to go through the process of wiring everything up again, which would include your speakers. We will not detail how you would connect a harness in this article, but the principles used below are the same if you would like to connect a harness to your wiring system.

You Can Use a Soldering Method to Connect Your Speakers to Your Radio.

The best way to connect your speakers to your radio is by soldering your radio wire to your speakers’ wire and using heat shrink tubing to seal the wires and keep them together. I am having a great soldering experience with using a simple Iron Kit. It is available on Amazon, so check the latest price now.

This method is preferred because there is less room for error once the wires are soldered and connected, and also soldered connections are more robust. This means they won’t break or fault quickly. It is a huge hassle to remove a dash and radio just to get to one loose wire.

All you would do is strip either end of your speaker wire and radio speaker wire, placing the heat shrink tubing around the wire before soldering them together.

After you have soldered both wires, you would use a heating device (a hair dryer works well) to seal the heat shrink tubing around the soldered area of the wire.

You Can Use a Crimp Clamp to Connect Your Speakers to Your Radio.

If you do not want to play with hot temperatures, you can crimp the wires together. Just purchase Amazon terminal connectors designed to hold two wires together, creating a connection.

These little fittings that can be bought and used for car audio systems are called crimp clamps. The principle is the same as using a soldering iron to fuse the wires. However, in this case, you just need these little clamps and a crimping device to squeeze the ends down tightly.

What you would do is again strip the wires on both ends of the speaker wire and the radio speaker wire and then push each end of the wires into the crimp clamp. All you would do then is crimp both sides of the device, and the cables would be held securely in place.

As a final note, just remember in all instances when connecting your speakers to a radio, keep the colour-coded system that tells you which wire is for which speaker in mind.

Conclusión

We determined that it was pretty straightforward to connect your speakers to your car radio without a harness because a harness is just a type of device or system that aids in connecting wires more efficiently for our purposes using a little plastic connector.

A harness is not necessary for wiring devices together. The only factor you really need to consider is what method you want to connect the speakers with the stereo.

Lastly, the two methods of connecting your car speakers to the car stereo are either soldering or using crimp clamps. Both techniques are simple and can save you money on the expert.

How to Straight Wire a Car Radio to the Battery?

To connect the radio straight to the battery, you have to put together the yellow wire with the red one and run it to the positive battery terminal.

You have to run the black (ground) wire to the negative battery terminal.

Such connection is possible and often used, especially in older cars, but the radio is more difficult to control, and it may drain your battery overnight if you forget to turn it off.

A better solution is to wire the stereo to an ignition switch so that it only has power when the car’s engine is on.
