Come collegare gli altoparlanti dell'auto alla radio senza il cablaggio?
Se ti chiedi se è necessario un cablaggio radio per collegare i tuoi altoparlanti all'unità principale e non sai cosa fare se non ne hai uno, questo articolo fa per te.
Esistono un paio di metodi che puoi utilizzare per collegare gli altoparlanti senza il cablaggio e sono relativamente semplici.
Quando l'autoradio non ha un cablaggio o quando il cablaggio o i cavi esistenti sono danneggiati, il modo più semplice per collegare gli altoparlanti è utilizzare un adattatore per il cablaggio dell'autoradio
L'articolo seguente descriverà in dettaglio ogni aspetto di un cablaggio e degli altoparlanti, considerando tutti i fattori necessari per collegarli alla radio.
Ciò includerà cos'è un cablaggio, ne hai bisogno, è possibile fissare gli altoparlanti senza un cablaggio, come collegare gli altoparlanti senza un cablaggio, vari metodi per farlo, specifiche del cavo dell'autoradio come il colore e il calibro del cavo dell'altoparlante e lunghezza.
Capire un cablaggio
Quando provi a collegare gli altoparlanti della tua auto senza un cablaggio (anche se non è difficile), puoi prenderne in considerazione uno per la loro convenienza e disponibilità, anche per sistemi aftermarket come altoparlanti e radio.
Ottieni anche cablaggi più piccoli che funzionano come una mini versione separata che ti consente di aggiungere ulteriori cablaggi o effettuare configurazioni se necessario.
Ho bisogno di un cablaggio per installare gli altoparlanti dell'auto?
Un cablaggio semplifica il collegamento dei cavi audio dell'auto. Un cablaggio può ospitare fino a 15 fili (un'autoradio standard) o anche di più se la tua auto ospita un'unità di infotainment DIN o doppio DIN. Sarebbe un compito arduo, soprattutto a livello di produzione di autoveicoli, dover cablare i componenti a mano l'uno con l'altro tutto il tempo. Da qui è stato creato questo piccolo dispositivo che supporta l'intero sistema.
I cablaggi possono essere utilizzati anche per situazioni speciali in cui tipi di connessione e connettori semplici come i connettori a crimpare non funzionano.
A seconda dell'impianto stereo dell'auto di cui disponi e di quali componenti comprende, collegare i tuoi altoparlanti senza cablaggio non sarà troppo difficile.
Tieni presente che un'imbracatura non è troppo costosa e sono relativamente facili da trovare, anche se ne hai bisogno uno specifico. Puoi contattare il produttore della tua autoradio e chiedere loro chi sono i loro fornitori, e puoi contattare un negozio di ricambi per auto usate e cercare di trovarne uno lì.
Tuttavia, non hai essenzialmente bisogno di un cablaggio per collegare gli altoparlanti dell'auto alla radio.
I cavi degli altoparlanti fanno parte del cablaggio dell'autoradio
I cavi degli altoparlanti sono la parte più grande delle connessioni del cablaggio. Un cablaggio standard per autoradio con 15 punti di connessione dedicherà fino a 8 punti di connessione solo per i tuoi altoparlanti.
Questo perché l'autoradio o l'amplificatore di solito hanno quattro canali di due altoparlanti ciascuno (anteriore e posteriore) e ogni canale deve avere un terminale positivo e negativo.
Un cablaggio aggiunge funzionalità aggiuntive?
Il ruolo di un'imbracatura è relativamente semplice. Deve collegare elettricamente dispositivi elettrici e componenti elettrici installati all'interno della tua auto. Pertanto, un'imbracatura può essere utilizzata per la maggior parte degli elementi del tuo veicolo, come il sistema di illuminazione, i ventilatori, i condizionatori d'aria, la radio e così via.
Un cablaggio è composto da molti singoli fili che svolgono ruoli specifici. Questi possono includere l'invio di alimentazione costante, dispositivi di attivazione, trasmissione di informazioni o guida a distanza per altri dispositivi.
Tutte le autoradio hanno gli stessi connettori (tipi di connessione)?
Molto probabilmente tutte le autoradio avranno il tipo di connessione maschio e il tipo femmina che puoi acquistare, altrimenti sarebbero collegate alla tua auto. Inoltre, tutte le autoradio aftermarket possono utilizzare lo stesso cablaggio.
Come faccio a sapere quali sono i cavi degli altoparlanti?
Tutti i sistemi audio e autoradio sono ora codificati a colori in base a uno standard specifico, in modo da sapere quali cavi sono in quali colori. Ci sarà sempre lo stesso colore per lo stesso filo, indipendentemente dall'auto o dalla radio che stai cercando di modificare.
Che cos'è il codice colore dei cavi dell'autoradio?
Per la maggior parte, l'autoradio e il cablaggio verranno forniti con otto fili per ciascun altoparlante, e questi sono i colori su cui vogliamo concentrarci quando si collegano gli altoparlanti:
Grigio
I cavi grigi vengono utilizzati per collegare gli altoparlanti anteriori di destra allo stereo. Il filo grigio è positivo e il grigio/nero è negativo.
Bianco
I fili bianchi collegano gli altoparlanti anteriori di sinistra all'autoradio. Il filo bianco è positivo e il filo bianco/nero è negativo.
Viola
I cavi viola collegano gli altoparlanti posteriori destro all'autoradio. Il filo viola è positivo e il filo viola/nero è negativo.
Verde
I fili verdi collegano gli altoparlanti posteriori sinistro all'autoradio. Il filo verde è positivo e il filo verde/nero è negativo.
Dovresti tagliare il cablaggio dell'autoradio?
Questo vale solo se hai una nuova radio e devi installarla. Quando acquisti una nuova radio o unità principale per la tua auto, molto probabilmente verrà fornita con un cablaggio già montato con una connessione di tipo maschio all'estremità. Questa imbracatura avrà probabilmente una lunghezza piuttosto estesa.
Una nuova radio o unità principale viene fornita con un cablaggio così lungo perché alcuni veicoli necessitano di una lunghezza del cavo maggiore per raggiungere la sezione o le sezioni della loro auto per collegarla.
Non c'è niente di peggio che acquistare una nuova radio o un'unità principale per scoprire che la lunghezza del cavo è appena inferiore a dove deve essere collegato.
Tuttavia, alcune auto sono progettate per ospitare la radio e un'area di cablaggio più piccola. 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.
Conclusione
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 Install a Car Radio Without a Wiring Harness?
A wiring harness adapter is commonly used in aftermarket installations, but when it is not available, connecting all wires will be complicated.
To connect the car radio without a harness right, follow the steps below:
#1. Unplug the car battery to avoid shocks while working on your car stereo.
#2. Find your serial radio harness and unplug it from the back of your radio.
#3. Find all of the wires that need to be connected to the back of your new radio. You will need a wire for each function, including:
- Power (constant 12V+)
- Ground
- Ignition switched power (12V+ when the key is in the “Run” position)
- Illumination or dimmer control (usually a brown or yellow wire)
- Power antenna (remotely turns on your radio’s power antenna)
- Amp remote wire (turns on your car amplifier, if you have one)
- Left front speaker (+)
- Left front speaker (-)
- Right front speaker (+)
- Right front speaker (-)
- Left rear speaker (+)
- Left rear speaker (-)
- Right rear speaker (+)
- Right rear speaker (-)
#4. Your new radio will likely have a spot to plug in the serial radio harness, but if it does not, you will need to cut and splice the wires to connect them.
#5. Wrap any exposed wire with electrical tape to avoid short circuits.
#6. Once all the wires are connected, plug in the car battery and test your new radio.
#7. If you install a new car stereo, you will also 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.
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.
