We install 16 cm speakers in the front doors of a Lada Granta with our own hands

Once, after parking for a week, the car would not start - the battery was completely discharged...

The battery was removed for subsequent charging and the next day the search for the gluttonous culprit began; the current consumption of the armed car for 3 minutes was an indecent 150 mA.

After suspicions from the signaling were removed, it was time to check the radio (Alpine CDE-170RM): 1. Turn on the radio - the current consumption increased to 530 mA; 2. Turn off the radio - the current consumption dropped to the same 150 mA; 3. We remove the radio socket - the current consumption has dropped to a remarkable 40 mA.

It turns out that the visually disabled radio does not turn off completely and consumes as much as 110 mA, which is too much for the settings memory, however.

Of course, you don’t have to bother and remove the panel every time, but it’s interesting to get to the bottom of the problem.

We check the connection of the power part of the radio to section A of the ISO connector - everything is in order, as per the instructions, although it was confusing that when the ignition is turned off, there is + 12V from the ignition switch on the connector contact, which should not be there, we take it out, look and are surprised:

To figure out what’s what, let’s find the pinout of this connector on the Internet and compare it with the image of the connector:

It is worth noting that not all radios are susceptible to this “problem”; some of them can turn off completely even with this connection, so you need to check.

As always, the Internet helps out - after a short search, a simple and elegant solution was found based on two diodes:

To implement this scheme, we will need to run an additional wire to the radio connector. Since the main consumption of the radio comes through the constant + 12V contact from the battery (usually a thick yellow wire), and the 7th contact simply allows it to be turned on (usually a thin red wire), a wire with a cross-section of 0.5 mm2 was pulled from the fuse box, 31 th contact:

For those who are not familiar with the principle of operation of diodes, I made the following picture:

After all the modifications, the turned off radio no longer consumes current, and to listen to music in a turned off car, you just need to perform 3 steps: 1 - Turn on the ignition; 2 — Turn on the radio; 3 - Turn off the ignition.

The Granta in Standard and Norma configurations comes from the factory without a radio. AvtoVAZ did everything to simplify the installation process: it ran the power and acoustic wires, installed the antenna and threw the wire into the cabin. All that remains is to plug in the speakers and head unit. Let's look at how the Lada Granta radio is installed.

Installation of 1 din radio in Grantu standard and norm

What is needed to install a radio in a VAZ 2190:

• The radio itself is also the head unit;
• flat screwdriver;
• Straight arms.

Abbreviations and symbols in the text:

• GU – head unit;
• MMS – multimedia system;
• DIN (din) – installation size for acoustics in a car.

Step-by-step instructions for installing the head unit

1. a narrow flat screwdriver or plastic spatula for installing acoustics;
2. 1-din radio with frame.

The seat in Grant is designed for 1 din.
To work with large 2-din sizes, you will need to cut out the partition and install a decorative frame. Step 1 . Using a flat-head screwdriver, remove the plastic plug for the radio. To do this, carefully pry it around the edges and pull it towards you.

The placeholder for the radio is installed from the factory.

Step 2 . On the back of the plug there is a mount for ISO connectors. There are two connectors: music power and wires for the speakers.

Step 3 . If necessary, connect an adapter for your radio to the ISO. Usually it comes included .

If an adapter is not needed , proceed to step 4.

If an adapter is needed for acoustics, it is included in the kit. Example in the picture.

Step 4 . We remove the glove compartment. Holding the glove compartment clamps in the upper position, forcefully lower the glove compartment down.

Overcoming resistance, we pull the lid towards ourselves - the glove compartment is removed.

Removing the glove box on a Grant is easy when you know where its latches are located.

Step 5 . We climb under the panel in the area of ​​the front right passenger's feet with a flashlight. Behind the felt on top we find a thick black wire - at its end there is a plug for the factory antenna.

I have no voltage at all on rem. I connected everything as expected and nothing. The amplifier does not turn on. I threw + on the amp itself, some kind of squeal and that’s it. And the engine behaves as if the air conditioner was turned on

thanks for the diagram! verified to work!

I connected an amplifier to MMS 2190, everything worked for a couple of days, then the signal channel failed, blue wire, maybe you don’t know? KIX amplifier 600 watt. mms 2190 new

Unfortunately there is little information

Namely, isn't there a remote control in the original wire block? so as not to take 8.5 from the adapter and solder the scarf?

Not available in all trim levels. If you turn on reverse speed and the music is muffled, then there is already a wire in a1. If not. You need to pull it or take it from the cable

It is muffled, but there it works like the remote, when you turn on the ignition there is 12 V and it doesn’t matter whether the rear is on or not? And isn’t it activated for me if the music fades out at the back? I have an option that you can solder to the antenna

Removing the standard radio in Grant Lux

The difference between grants of the luxury configuration: the MMS (multimedia system) installed from the factory. This is a 2 din device.

To remove standard acoustic grants :

• take a knife or plastic spatula to dismantle the acoustics and disconnect the decorative trims to the right and left of the radio. It is not necessary to take pictures;
• in the gap between the cover and the panel we find the head unit lock. There are two of them on both sides. Press it out with a screwdriver;
• we take out the GU on ourselves.

Everything is described in detail in the video:

Replacing the standard MMC in Grant

The process - after removing the acoustics, we install a new system.

Difficulties : you may have to finish the fastenings of the new system for VAZ ones. Plus you need the right frame. The factory MMC frame may not fit.

Have you bought a new 2 din radio, but there is no frame for sale? You can do it yourself . Example at the link.

How to install 2 din in grant norm or standard

Everything is more complicated here. Need to:

• dismantle the center console trim - unclip the fastenings, move it forward and disconnect the buttons and heater handles;
• cut out a vertical plastic partition that will not allow you to install a 2 din device;
• cut down the plastic casing of the central air duct;
• try on a new acoustic unit, adjust the fastenings if necessary;
• install adapters from the delivery kit on the wiring (if required);
• install the device;
• if we leave the old center console trim: we cut out the partition, try it on, put it in place with the buttons and handles connected, adjust the decorative frame of the control unit, install it;
• if we install a new trim on the console under a 2 din device: we transfer the heater control unit and buttons from the old trim, install them in place, and put a decorative frame on the control unit.

Instead of a total

• If we install a simple radio, the size should be no more than 178 * 50 mm. Installation requires plastic spatulas or a screwdriver. Adapters and slides are included .
• To install 2 din, you need a new overlay on the console, a decorative frame on the GU itself, wire cutters and a metal blade to adjust the installation location.
• Are we replacing the standard speakers with another of the same size? Still need a new decorative frame . Otherwise, gaps in the panel will be visible.

More articles about Granta here.

Since the beginning of 2011, all Lada Granta models have been manufactured with audio preparation: factory radios and receivers. The quality of reception and sound is not always at the highest level due to its cheapness and simplicity. When purchasing a Lada Grant from the showroom, the owner receives audio preparation, acoustic wires, and installed electrical wiring.

Installing front speakers

Acoustics for Lada Granta

Before moving on to the actual algorithm for installing the front speakers (see How to choose speakers for a car radio on your own), let us remind you that this car has already been equipped with standard seats and there is no need to do anything new. But a serious problem arises when installing two-component acoustics. And yet, modernization will have to be carried out, since the diameter of the standard seats is quite limited, however, as on other car models.

Note. If, for example, we want to install high-quality 16 cm acoustics on a Lada Granta, then another intractable problem will arise. The front windows may not open all the way and will hit the speaker. You will have to make special spacers from plywood or chipboard.

Making podiums

• The first thing to do is to make podiums.

Choosing the right radio size

We carry out installation either independently or by contacting specialists at the service center. In the second case, the service is paid.

By default, all VAZ and Lada models are equipped with a 1-DIN radio. The opening dimensions correspond to: 180 x 50 mm. This is an old standardization that has been in force since the times of the USSR. Modern audio modules can be purchased complete with a pre-installed LCD display. The size of the opening must comply with the standard: 180 x 100 mm, that is, doubled in height. Size marking: 2-DIN.

To install the radio in the Granta liftback, cut out the top pocket, remove the plastic, and install the assembled module. For a beginner, the process will seem somewhat complicated, so strictly follow the instructions.

Features of audio system installation

When connecting the stereo system wiring, it is necessary to take into account certain features of the electrical supply. This is provided using red and yellow wires. The first is responsible for remembering the audio system settings, the second is for turning off the radio, which is controlled by the car’s ignition.

It is recommended to use a parallel connection type for both wires so that the audio system can only be turned off manually. In this case, it will not be affected by the car’s ignition key, but there will be a problem of excessive electricity consumption in parking mode, which is solved by installing a special regulator for the red electrical wire. With its help, you can turn off the radio by hardware when leaving the car for a long time. This regulator can be connected to the alarm system, that is, when the vehicle is locked, the audio system will turn off automatically.

The disadvantage of this system is the extra current consumption, but in any case it is much less than the indicators that provide power to the radio during standby mode.

If the audio system suddenly turns off due to excessive volume, display flickering, or high-pitched sounds, it is not due to a power failure. This situation occurs when the car battery is discharged and the current ceases to be constant. The problem is solved by connecting an additional capacitor, which provides constant power to the radio.

Once you have successfully connected all the necessary connectors to the car's electrical wiring, you can begin installing the front and rear speakers.

How to connect a Lada Granta head unit with a 1-DIN connector

• We carry out the work inside the car, having previously disconnected the terminals from the battery in order to prevent a short circuit in the circuit;
• We remove the plastic partition - pocket. It covers the hole, preventing objects from falling inside the torpedo. We use a flat-head screwdriver to unscrew the bolts;
• Two ISO plugs are visible behind the partition body. These types of wire terminals are manufactured in accordance with international automotive standards. More than 98% of all automakers use the standard when equipping technical equipment;
• We remove the metal frame - the block - from the body of the audio unit and place it in the cavity of the torpedo.
• We first connect the blocks with wires. Fitting into the connectors is accompanied by a characteristic click;
• We insert the module into the metal frame.

Note to the driver. Incorrect terminal connections result in a short circuit. To ensure the safety of the connection process, the connectors have guides that allow you to install the block in only one position.

The main differences between coaxial and component acoustics

• Coaxial: a single design of speakers, where low-frequency and high-frequency are mounted on the same axis. Depending on the type of preinstalled crossover, one, two, or three-way crossovers are distinguished.
• Component: consists of a number of individual different-frequency speakers that are installed throughout the vehicle interior.

It is better to install coaxial ones on the back row of seats, component ones - in the front. The cost of coaxial speakers is a third cheaper than component ones.

Common mistakes when installing a standard Granta liftback radio with your own hands

• when connecting additional terminals, manual twisting of wires is used instead of classical soldering;
• regular insulating tape is used on connections instead of heat-resistant sleeves;
• Incorrect connection of a large number of speakers on one branch leads to overload, heating, and short circuit.

Installing a sound amplifier

By liftback radio amplifier we mean:

• crossover installation;
• subwoofer installation.

The choice is up to the owner of the Lada Grant, as different goals are pursued: cleanliness, sound quality. Obviously, the cost of equipment will also increase. Crossovers are installed in the cavity of the glove box, since their dimensions do not exceed 100 x 150 mm and are rectangular in shape. Subwoofers are fixed in the luggage compartment. Equipment requires more space.

Connection of an external device is carried out strictly in accordance with the operating instructions:

• brown wire color: responsible for the operation of the system;
• black: power supply to equipment;
• yellow: audio module activation;
• red: settings and programming.

At the very end, do not forget to connect a red wire with a pre-installed fuse to the positive terminal of the battery. It directly connects the amplifier (subwoofer) to the current source.

Installing two speakers in the front doors

1. dismantle the door card, handle, control unit;
2. We compare the standard cutouts for the speakers with the actual dimensions. If necessary, expand with a file or fine sandpaper. It is strictly forbidden to use cutting objects, as there is a high risk of damage to the plastic of the door card;
3. we check for the absence of roughness in the hole, install the speaker, fix it, connect the standard terminals with wiring;
4. we check the operation of the speaker, install the door card, and fix the metal grille to protect the speaker from mechanical damage.

Characteristics of the standard radio "Lada Grants Liftback"

The radio for the Lada Granta liftback is supplied as standard equipment. Product in 2-DIM format (100 x 180 mm).

In addition to the classic radio, there is a built-in card reader, Bluetooth, and a USB output for connecting flash drives. The only disadvantage of the audio module is that it is a push-button type. Which is not to the liking of many car enthusiasts, which is why they install more modern modifications.

During the startup of the audio module, a greeting from Lada Kalina 2 is displayed. This is not an error, as many owners think. This type of audio was originally developed for the Lada Kalina 2. Obviously, the manufacturer did not change anything and started production for the Granta. Installation/disassembly of the module is somewhat complicated due to the tight fit, so be prepared for this.

How to flash the firmware

• Buy an SD card, format it in FAT, exFAT format;
• We download the firmware for free on the manufacturer’s official website;
• We save the data in the root directory of the SD card;
• We insert the SD card into the slot on the radio, start it, wait for the update to finish;
• Turn on and off the module;
• We customize the new interface for ourselves.

If the firmware is installed incorrectly, additional screen calibration using the CAN bus will be required. It is impossible to do this yourself, only in a service station. After successful flashing, the following is available:

• graphic equalizer;
• viewing photos, pictures, videos;
• improved sound quality;
• possibility of installing a navigation system.

Disadvantages of a standard radio

• Outdated firmware from the “box”;
• Not all options are initially available;
• The need for periodic software updates;
• Push-button interface.

Reviews

Conclusion The opinions of motorists on the functionality and sound quality of the standard radio are divided, which is obvious. Everyone evaluates according to their own criteria. Some people care about sound, others about functionality, and others about control. Regardless of the type of radio: push-button or touch-sensitive, the workmanship is good. No massive breakdowns or defects were recorded. Maintenance is not expensive, parts and components are available both at official representative offices and on the Internet. Now it will not be difficult for the owner to remove the radio on the Granta liftback with his own hands without contacting a service station.
