Comment brancher des haut-parleurs de voiture à la radio sans le faisceau ?
Si vous vous demandez si un faisceau de câblage radio est nécessaire pour connecter vos haut-parleurs à l'unité principale et que vous ne savez pas quoi faire si vous n'en avez pas, cet article est pour vous.
Il existe plusieurs méthodes que vous pouvez utiliser pour connecter des haut-parleurs sans le harnais, et elles sont relativement simples.
Lorsque votre autoradio n'a pas de faisceau ou lorsque le faisceau ou les fils existants sont endommagés, le moyen le plus simple de connecter les haut-parleurs consiste à utiliser un adaptateur de faisceau d'autoradio
L'article ci-dessous détaillera tous les aspects d'un harnais et de haut-parleurs, en tenant compte de tous les facteurs nécessaires lors de leur connexion à votre radio.
Cela comprendra ce qu'est un harnais, en avez-vous besoin, les haut-parleurs peuvent-ils être sécurisés sans harnais, comment connecter des haut-parleurs sans harnais, diverses méthodes pour le faire, les spécifications de fil spécifiques à l'autoradio telles que la couleur, ainsi que la jauge de fil de haut-parleur et longueur.
Comprendre un faisceau de câblage
Lorsque vous essayez de connecter vos haut-parleurs de voiture sans faisceau (bien que ce ne soit pas difficile), vous pouvez en envisager un en raison de leur prix abordable et de leur disponibilité, même pour les systèmes de rechange tels que les haut-parleurs et les radios.
Vous obtenez même des faisceaux plus petits qui fonctionnent pour servir de mini version séparée vous permettant d'ajouter un câblage supplémentaire ou de faire des configurations si vous en avez besoin.
Ai-je besoin d'un faisceau de câbles pour installer des haut-parleurs de voiture ?
Un faisceau de câbles facilite la connexion des fils audio de la voiture. Un faisceau peut contenir jusqu'à 15 fils (un autoradio standard) ou même plus si votre voiture abrite une unité d'infodivertissement DIN ou double DIN. Ce serait une tâche ardue, en particulier au niveau de la fabrication de véhicules automobiles, de devoir câbler les composants à la main les uns aux autres en permanence. C'est pourquoi ce petit appareil qui prend en charge l'ensemble du système a été créé.
Les harnais peuvent également être utilisés dans des situations spécialisées où les types de connexion simples et les connecteurs tels que les connecteurs à sertir ne fonctionneront tout simplement pas.
Selon le système stéréo de voiture dont vous disposez et les composants qu'il comprend, connecter vos haut-parleurs sans harnais ne sera pas trop difficile.
Gardez à l'esprit qu'un harnais n'est pas trop cher et qu'il est relativement facile à trouver, même si vous en avez besoin d'un spécifique. Vous pouvez contacter le fabricant de votre autoradio et lui demander qui sont ses fournisseurs, et vous pouvez contacter un magasin de pièces automobiles d'occasion et essayer d'en trouver un là-bas.
Cependant, vous n'avez pas nécessairement besoin d'un faisceau pour connecter les haut-parleurs de la voiture à la radio.
Les fils des haut-parleurs font-ils partie d'un faisceau d'autoradio
Les fils des haut-parleurs constituent la plus grande partie des connexions du faisceau. Un faisceau d'autoradio standard avec 15 points de connexion consacrera jusqu'à 8 points de connexion uniquement pour vos haut-parleurs.
En effet, votre autoradio ou amplificateur aura généralement quatre canaux de deux haut-parleurs chacun (avant et arrière), et chaque canal doit avoir une borne positive et négative.
Un faisceau de câbles ajoute-t-il des fonctionnalités supplémentaires ?
Le rôle d'un harnais est relativement simple. Il doit connecter électriquement les appareils électriques et les composants électriques qui sont installés dans votre voiture. Par conséquent, un harnais peut être utilisé pour la plupart des éléments de votre véhicule, tels que le système d'éclairage, les ventilateurs, les climatiseurs, la radio, etc.
Un faisceau de câbles est constitué de nombreux fils individuels qui jouent des rôles spécifiques. Celles-ci peuvent inclure l'envoi d'une alimentation constante, le déclenchement d'appareils, la transmission d'informations ou le pilotage à distance pour d'autres appareils.
Tous les autoradios ont-ils les mêmes connecteurs (types de connexion) ?
Tous les autoradios auront très probablement le type de connexion mâle et le type femelle que vous pouvez acheter, sinon ils seraient autrement connectés à votre voiture. De plus, tous les autoradios du marché secondaire peuvent utiliser le même faisceau.
Comment savoir quels fils d'enceinte sont lesquels ?
Tous les autoradios et systèmes audio sont désormais codés par couleur selon une norme spécifique, vous savez donc quels câbles sont dans quelles couleurs. Il y aura toujours la même couleur pour le même fil quelle que soit la voiture ou la radio que vous essayez de modifier.
Qu'est-ce qu'un code couleur des fils d'un autoradio ?
Pour la plupart, l'autoradio et le faisceau seront livrés avec huit fils pour chaque haut-parleur, et ce sont les couleurs sur lesquelles nous voulons nous concentrer lors de la connexion des haut-parleurs :
Gris
Les fils gris sont utilisés pour connecter les haut-parleurs avant droits à votre chaîne stéréo. Le fil gris est positif et le fil gris/noir est négatif.
Blanc
Les fils blancs relient les haut-parleurs avant gauche à votre autoradio. Le fil blanc est positif et le fil blanc/noir est négatif.
Violet
Les fils violets relient les haut-parleurs arrière droits à votre autoradio. Le fil violet est positif et le fil violet/noir est négatif.
Vert
Les fils verts relient les haut-parleurs arrière gauche à votre autoradio. Le fil vert est positif et le fil vert/noir est négatif.
Devez-vous couper le faisceau de câblage de l'autoradio ?
Cela ne s'applique que si vous avez une nouvelle radio et que vous devez l'installer. Lorsque vous achetez une nouvelle radio ou une nouvelle unité principale pour votre voiture, elle sera très probablement livrée avec un faisceau déjà installé avec une connexion de type mâle à son extrémité. Ce harnais aura probablement une longueur assez longue.
Une nouvelle radio ou unité principale est livrée avec un faisceau aussi long car certains véhicules ont besoin d'une longueur de câble plus longue pour atteindre la ou les sections de leur voiture pour le brancher.
Il n'y a rien de pire que d'acheter une nouvelle radio ou une nouvelle unité principale pour découvrir que la longueur du câble est juste en deçà de l'endroit où il doit se connecter.
Cependant, certaines voitures sont conçues pour abriter la radio et une zone de câblage plus petite. 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.
Conclusion
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 Wire Car Speakers to the Radio?
To wire car speakers to the radio, you need to strip the end of the speaker wires and connect them to the corresponding cables coming out of the stereo.
When connecting, make sure to check which wires are positive and negative.
An incorrect connection will make speakers play in the reverse polarity, which negatively affects the audio experience and can cause damaging some sensitive speaker types.
How to Wire Aftermarket Radio Without Harness?
If you install a new aftermarket radio, I do not recommend installing it without the harness.
You will need to purchase a dash kit and car stereo installation kit. These kits will help you install your new radio without damaging your car’s dash.
Once you have all of the necessary parts, follow the instructions that come with the dash kit and installation kit to install your new radio.
If you are unsure how to properly install your new radio, consult a professional installer. Improper installation can damage your car’s electrical system and void the car radio’s warranty.
How to Wire Car Speakers Without Harness?
To wire car speakers to the radio without a harness, you need to strip the end of the speaker wires and connect them to the corresponding cables coming out of the stereo.
When connecting, make sure to check which wires are positive and negative.
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.
