Autosound. Myths about auto sound

Today, cars have ceased to be just a means of transportation, the more prestigious, the more beautiful the appearance. More and more amateurs and craftsmen began to invest their work in the interior decoration of the vehicle, which accordingly interested the buyer. After all, you can have a car like everyone else, but with a completely unique inner world – decoration, color, materials, sound system.

Car sound evolved from conventional two speakers to powerful subwoofers with dozens (!) Of speakers. Even began to host championships for car sound, which reveal the most powerful, most spectacular. It is no accident that many people show interest in equipping their car with a powerful and unique audio system, but there are many myths that put the uninitiated into a dead end. Debunking these errors and will do.

Power of my radio – as much as 200 watts!

The basis of error lies in the confusion of different concepts – the power of the nominal and the maximum. Typically, manufacturers of sound equipment indicate the maximum, peak power, but such indicators can be obtained only on special stands, almost in the laboratory. The usual consumer will not get such power simply by definition. If you want to know the real power, then look for the nominal parameters, if they are at least 4 * 15 W, then this is not bad. Many people are wondering, where did this difference in values ​​come from? The fact is that the peak power is the limit for the equipment, when the equipment reaches its end, the tests to achieve such figures are literally a test of survival. It is curious that manufacturers are embarking on some tricks to reach high figures, which, as you know, are better sold. Thus, during the tests, the equipment can be cooled with liquid nitrogen, which will help squeeze out their latest juices. But the numerous Asian brands, famous for their cheapness, do not get puzzled at all by testing, simply stating high power, taking it from the ceiling. The risk of being exposed by such manufacturers is minimal, since the user still can not verify these figures.

In a good expensive car, music is by definition excellent.

We will start from the conceptual bundle “quality auto sound”, which means first-class components that successfully combine with each other and installed in the car by specialists. Equipping machines with high-quality sound is unprofitable, first of all, for the manufacturer – where is the guarantee, what is an auto, with a weighty price premium, will sell well? Qualitative sound will be appreciated only by professionals, and practice shows that they are still trying to improve on their own what they already have. Experts note that models with a really cool built-in audio system are units, among them one can call the Audi A8, which has the Bang @ Olufsen acoustics, or the Volvo S80 with the Dynaudio system.

There are 12 speakers in my car, they give a stunning sound!

Quality sound does not depend on the number of speakers. In the case of using mediocre quality equipment, one can get the opposite effect: all the noise, rattles will sound simultaneously from all 4 (8,10,12) speakers. In most cases, it’s enough to have a powerful front, a subwoofer and a 4-channel amplifier for strong and beautiful sound. The increase in the number of speakers in the car is often insisted not by engineers, but by marketers. Not surprisingly, in the segment of the most expensive systems, the number of speakers is approaching two dozen. For example, in the Lexus audio system Mark Levinson consists of as many as 19 columns located throughout the salon. Naturally, mostly they perform image functions, rather than somehow complement the sound. Often the shape of the speakers, their size and location depends on the imagination of the designer. You can see a beautiful speaker in the most secluded place, but in fact it will be almost empty.

An active subwoofer can replace several other components.

The difference in the active and conventional subwoofer is that in the first case the amplifier is placed directly in the case. In fact, this neighborhood is not indisputable from the point of view of efficiency. It is better to choose the option with the placement of a subwoofer in the trunk, and the amplifier – in the cabin, the seat of a passenger is perfect for this. Naturally, the active subwoofer is much larger in size, so it takes quite a bit of space in the trunk. Myth is born of simple human psychology – well, how can “active” equipment be worse than “passive”?

The more different functions in the audio system, the better.

And again, the hand of marketers can be traced, which provide the devices with a bunch of additional functions. The phone must have internet access, an audio system – a TV and GPS navigation and so on. Usually the consumer is faced with the fact that some of the many components work unimportantly. Attempt to give the device a lot of extraneous functions is inherent mainly to firms that are looking for their buyer in the lowest price category. Solid companies do not exchange for small things, paying attention to the quality of sound directly. For example, in the head units of Pioneer the radio is completely separate from the CD player. So do not rush to the radio with functions of an alarm clock, game center, navigator and other things, follow the proverb: “Better less, yes it is better.”

It is better to select the components so that they belong to the same brand.

It is not difficult to understand the logic of such people, who obviously want to solve the compatibility problem in this way. In a specialized magazine, you can see how among the, say, head devices, the company N became the winner. Often the buyer goes to the store, simultaneously buying not only this product, but also a subwoofer, amplifier, speakers of the same company. Collecting the entire set, the buyer will naturally be satisfied, at least from a moral point of view. Meanwhile, often firms that produce the best head units are rather mediocre in the production of other acoustics, producing it only to fill the line of components. What is the reason, you ask? The whole hitch is that it is inside different components. For example, in the case of a radio tape recorder, there will be microelectronics inside, based on modern relevant technologies, but in the case of a speaker – macroelectronics. The professional seller will tell you which manufacturer is strong in which components, but the illiterate seller and will try to sell a whole set of products of one firm.

аку The acoustics of an automobile manufacturer is better for a car.

Indeed, the car is better to choose “native” parts (bulbs, swords, etc.), but that’s only auto sound in this list is not included. By the way, few automakers in general make acoustics themselves, you can remember except that Daewoo and Hyundai. Usually, manufacturers order such devices on the side, only marking them with their logo. But, as has already been discussed, the staffing system is by no means the best option. Experienced music lovers generally try to abandon the built-in audio system when buying a car. There is also a clear benefit, and saving time when installing the hand-picked version. Here we also touch upon another myth. Many people think that the quality of the work of standard equipment can be corrected by buying an expensive subwoofer. However, this is not so – for the work of good technology you need a full quality complex, and in conjunction with mediocre any products will begin to trash.

It’s better to choose the acoustics that won the auto sound competition.

Actually, there are different competitions. Some of them related to the SPL (Sound Pressure Level) are aimed at giving the maximum volume of sound. For these purposes, the machine is equipped with all kinds of “rolls”, reinforce the glass, so that not the ones flew away, and the sound is triggered by the remote device, being at a distance to not deafen. But this has no direct relationship to the quality of sound.In order to determine really worthwhile equipment, it is necessary to investigate the general composition of the background music, how half-tones appear, and how the sound components influence each other. To fully test the equipment even selected several records of different styles. That is, a quality sound makes it possible to hear all the nuances of music, both individually and in a single sound.

It is best to install audio equipment in a “sedan” type enclosure.

This myth is rather ancient and has almost become obsolete today. Ten years ago, the audio system was a tape recorder with speakers, and few people heard of subwoofers. Myth was born of the following considerations. Only in the sedan behind the rear seats the shelf is rigidly fixed, and in other types of body it is mobile. Therefore, the speakers will experience shaking, which can affect the sound quality. Today, no one clings to the rear speakers, it is more effective to install a classy subwoofer and a powerful “front.” Today, the priorities literally turned upside down – it’s in the trunk of the sedan that the subwoofer is in isolation, while single-volume bodies are more suitable for car audio installation. In the sedan, the sound passes through the rear wall, but the compression effect will be noticeably weakened by it.

You can buy a capacitor and listen to music for hours without fear of planting a battery.

In an acoustic system, the capacitor accumulates energy, being ready to give it away at the first necessity. But the capacitor in no way replaces the battery, nor in this its purpose, because in any case it is powered by a battery, being a link of an electrical circuit. It will not be accurate to evaluate the performance of the capacitor in terms of how much time it will play music with the engine off. The specialization of the capacitor is very narrow – to give part of its energy in the event that the main source’s charge is not enough to ensure normal sound. This can happen if additional consumers of energy are connected, but a capacitor is required, in fact, only the most powerful systems, with an actual power of several hundred watts.

I’m good at electrical, so I’ll install the audio system myself.

This myth is a consequence of our difficult heritage, when everyone was simply obliged to be a turner, a mechanic, and an electrician. Today, there is no such need anymore, but there is still a consciousness in the minds that everything can be done by one’s own hands, one has only to listen to the advice of a knowledgeable person or to read the corresponding magazine, besides, one can save money. Nobody denies that it is easy to do the simplest work – to cut for example a radio tape recorder in the dashboard, but we are talking about professional auto sound. You need to choose from hundreds of combinations of dozens of necessary components, combine all this neatly with wiring, while “listening” to the scene in search of the perfect sound. To get a high-quality sound in the cabin, it’s not enough to collect all the components, you also need to configure them to transfer all the nuances of music. By the way, weak training is not only for garage masters, but also for many installers in dealerships. After all, usually there is no regular post “master of auto sound,” there is only a “master of additional equipment,” which deals with both the protection of the crankcase, plastic carcasses and car audio. Is it worth to expect from him really high-quality, jewelry work, which fully reveals the possibilities of expensive equipment?

Class music can be bought for little money.

Really cool audio system costs not 100 and not 300 dollars, unless you are looking for a budget option. Starting the search for technology, remember – miser pays twice. Decide on your requirements, then show the machine to specialists. For each car there is a standard algorithm of conversion, which, incidentally, can not be followed, having developed an individual plan.The main thing is that people who specialize in this particular car deal with auto sound are not doing dozens of other things in passing. After all, as the English proverb says: “The shoemaker makes good shoes because he makes shoes and nothing more than this.”
