How to connect a car stereo - this question is asked less often in the context of new cars, which have music players permanently built into the dashboard. However, this was not always the case, and the request is still relevant even for cars that are several years old. Until recently, this element was completely interchangeable. So how to do it so that nothing is damaged and you can enjoy the new device?

Installation of car radio "radio"”
In order to correctly install the radio for your car, you need to pay attention to several things. Some are simpler, others are more complicated, but everything is in order.
What are the sizes of car stereos?
The key to choosing the right radio is its size. Basically, there are two dimensions: 1-DIN car radios – radios with standard dimensions of 50 x 180 x 160 mm (height x width x depth); 2-DIN car radios – radios and multimedia stations, the height of which is twice as high as the 1-DIN housing (100 x 180 x 160 mm). If you are interested in how to connect a 2-DIN car radio, the procedure is exactly the same as and for a smaller device. Such a device only requires more space.
In some cases, low shelves may appear, which may make it a little difficult to choose a radio - some automakers took this step after installing a touchscreen. Also, some electronics collectors have changed the fastening holes of the radio to a DVD player. Despite these two cases, in the vast majority of cars we are dealing with a shelf for either a 1-DIN or a 2-DIN radio.
What you need to know before installing a radio in the car
Remember that the key to the radio's operation is its power supply. It must be connected in such a way that the device turns off and on when the key is turned in the ignition. In addition, the electric charge when the engine is not running should be large enough so that the maintained voltage, on the one hand, remembers the memory settings of the radio, and on the other hand, does not discharge the battery.
Car radios are relatively easy to disassemble, so if you want to remove the old device from the car, you will need keys. If one of these conditions is not met, two things can happen. Either the radio will lose encoded stations quite often (it is not necessary every time), or we will not start the car after a long parking. The reasons for this may be a poorly connected radio or a short circuit in the electrical system.
The key element when connecting the radio in the car is the cube and ego cables
The key to connecting the radio in the car is an ISO-cube, i.e. a special adapter that allows you to connect other devices than those used at the factory. In it, you will most often find the following wires:
– black – mass – power cable for connection to the negative pole of the battery;
- yellow - power supply unit - is responsible for not having to program the radio every time. It is connected to the positive terminal of the battery;
- red - power supply - responsible for the constant power supply of the radio. It is connected to the place where the current reaches only after turning the ignition key;
- red is thinner or rougher - the backlight, which is also connected to the power cable or to the outlet, which many manufacturers provide for this case;
- blue - antenna - this cable is becoming increasingly rare, but it is still possible to find it. He is responsible for controlling the antenna in cars in which it extends automatically after turning on the engine.
Attention! Depending on the brand, model or year of manufacture, the color may vary. So it's worth checking in the car's owner's manual to see if the cable assignment is correct. Otherwise, a short circuit is possible.
The color of the acoustic cables and the connection of the car radio
As you have already noticed, power cables have insulation of different colors. In order for the main panel of the radio to correctly transmit sound to the speakers, they must be connected correctly. In each of the speakers in the car, there are two narrower cables (plus - smooth and minus - with a black stripe or rough), which will be wrapped with the same insulation:
Gray wire – front right speaker (HF); Violet wire – rear right speaker (RR); White wire – front left speaker (LF); Green wire – rear left speaker. Be careful not to short the cables during installation. If the device is connected to a power source, a short circuit will occur.
Choose a car radio for your needs
The key point when choosing a radio is to choose a device with the functions you need. At present, the main differences are in the already mentioned size and in the methods of music reproduction. More and more radios have USB connectors, which are gradually replacing the CD drive. Many of them also have a wireless module, which is Bluetooth. This will allow you to easily connect the radio to your phone, thanks to which you can quickly play your favorite music from YouTube, Spotify or iTunes.
It is also worth paying attention to the capabilities that the devices can boast of. Modern radios can provide tone correction, better bass amplification or noise reduction. Some of them may also offer wireless connectivity, which allows you to talk on the phone while driving without breaking the law.
Manufacturing quality also matters - choose the color of the plastic accordingly. Check the colors of the radio - this can be very important if you drive a lot at night.
