Improving the sound of regular audio – practical tips and tricks

If the driver home stereo has a great sound, then over time he begins to pay attention to his car stereo. The result will not be very pleasant – after all, the differences can be, and at the same time, significant. Therefore, many people have interest: what needs to do in order for the standard multimedia system to sound at the proper level?

Normal sound is a relative concept; everyone understands it in their own way: some prefer to increase the volume of the undistorted volume; others want the sound to be similar with high-end homemade ones. However, in the latter case, it will be very difficult to change something, because the way it will be played in the house, it will never be like this in the car. The reason for this is quite simple – the room and the interior of the vehicle have different acoustic properties. In addition, the speakers may be completely absent; the speakers are located in those places where they can be conveniently installed, the same situation with the acoustic design. Therefore, you cannot compare home and car sound.

Thus, many argue that creating a high end in a car is very difficult or even impossible. However, it is still worth noting that you can get a normal sound, and it is sometimes not difficult to do it. Consider the main nuances.

What to do?

It is worth noting that, oddly enough, not all standard receivers sound bad – if such devices that provide high-quality sound of music, despite the conditions of its use. However, such recorders have one drawback – they are quite expensive.

On the other hand, if the driver wants to create a high-quality stereo in the cabin of the car, then he will still have to pay a considerable sum to implement his idea. Therefore, the choice is behind the user.

In any case, to get a good and high-quality sound, it is necessary to go through a phased process of upgrading the standard head unit. It consists of several levels, which we consider more closely.

Stage 1 – insulation

The most important in this process will be the creation of favorable conditions for the sound, getting rid of unnecessary sounds, and this applies to not only third-party sound effects, but also body. The reason for this is quite simple – all the speakers and other elements for playing music fixed on metal panels or in plastic upholstery. Such performance degrades the sound quality, so making noise insulation is extremely necessary.

To improve the reproduction of music by acoustics, it is necessary to get rid of unnecessary resonances, other interferences that may arise from exposure to metal. For this, it is best to use vibration-damping materials.

1. This insulating material is made of bitumen or rubber, adding to its various impurities.

2. The main feature of this insulation is the presence of high internal viscosity.

3. Most use sheets of this material, sometimes – viscous mastics.

With their help, metal overtones eliminated; the conditions for the functioning of the speakers are significantly increased. Some recommendations for choosing:

It is better to use heavier and harder materials for insulation – they provide more efficiency, but their installation will be a bit complicated;
thin and lightweight materials are installed, respectively, much easier, but their effectiveness is relatively less;
lightweight foams and fiber-based materials are considered only optional, since the principle of their work is slightly different, so they cannot absorb vibrations from metal.

Thus, the selection of this material must be treated with special care, and select the best tools that have higher vibration-damping properties.

Stage 2 – Replacing the regular speakers

To address this issue must be approached with caution, because not always the only replacement of the speakers can completely reincarnate the sound, making it high-class. In addition, sometimes replacing can lead to the opposite effect – the sound will be much worse.

It is important to note that very often, the standard speakers are not of high quality, but each element is ideally suited to each other. In addition, you feel the balance, which, when replacing the regular speakers can be destroyed. Especially, this applies to branded acoustics.

1. Very often, car manufacturers use reduced impedance in standard systems – as often 4Om used in a conventional audio system, but in regular systems, it is, in most cases, 2 ohms. Therefore, replacing 2 Ohm by 4 Ohm, you can get quiet acoustics, and increasing the volume will cause an increase in distortion.

2. Having decided to replace the regular speakers with others with the same resistance, for signal correction, you can also make a mistake. Since many types of branded native acoustics made to compensate for the characteristics of cheap speakers and the drawbacks of their design, replacing the dynamics of the signal adjustment will be inappropriate.

Get the best option is still possible. Now, many manufacturers and companies offer acoustic kits that fit only certain brands or even car models. Therefore, it will be easy to choose the optimal solution.

Stage 3 – upgrade without replacing the standard media receiver

In this case, it is necessary to output the original uncorrected linear signal, with which you can build a new audio system. However, this will not be so easy, for this, it is better to use the services of specialists in setting the sound in the car. This process boils down to using one of the following options:

«pulling out» a linear signal from the car radio. In many models, this will be the only and optimal solution. As a result, with a small financial outlay, you can get great sound; the standard system will «get» additional connections to the RCA connectors on the back side — additional output buffers;
if it is impossible to output a linear signal, then it is necessary to disconnect the speakers from the head unit and connect them to the new sound power amplifier. A special requirement for the amplifier is the presence of high-level type inputs;
the use of a digital processor will give the sound more power; with their help, you can create an original audio signal from individual frequency segments by making a signal correction in the opposite direction. They need to be set up using a PC or laptop, tablet. As a result, this signal must be transmitted to the new amplifier, as a result, the sound will change significantly, for the better;

However, this method cannot always be used, because in some audio systems the signal is intentionally corrected. Therefore, in this situation, receiving the wrong signal from the staff to the new amplifier is inappropriate. If the system is equipped with a gain channel-by-channel, then the output of the curve signal is completely impossible.

the latter option can be used in cars where a MOST bus is used. To optimize the audio system, it is necessary to use a MOST adapter, which is included in the system, «pulling» a digital audio signal from the bus in the form of a regular SPDIF. Then the process is already familiar – you can choose the best processor option with a built-in amplifier, systems with external audio DAC and other innovative devices to improve the sound quality.

The choice, of course, is yours, and it is necessary to choose the best option based on the design features and the construction of the standard system in the car.

Stage 4 – replacing the standard system

In the case of not only poor sound, but also poor-quality functioning of a standard car receiver, you can make a complete replacement of all components. First, you need to have a good look at the head unit and determine if other car systems connected to it – the on-board computer or the climate control. If not, then you can safely change it without changing any functionality of the machine. In the case of a full relationship with climate control or on-board computer, then the replacement process will be a little more difficult or even impossible. This is individual for each case and is likely to entail many financial expenses.

In the case of the size of the media receiver, there will also be no difficulties, since manufacturers now provide different transition frames, thanks to which you can connect a 1DIN radio tape recorder to a 2DIN. Manufacturers of car stereos also provide devices that are suitable for a certain brand or model of car, and are located in the panel part on the pin-to-pin principle.

An interesting option would be to use the car radio without changing the head unit. Thus, the user connects the new media receiver to the staff one, making the latter additional. As a result, the audio system will be built on a new device, and then the sound of the music will become better and more powerful.
