Since an audio system is not something very necessary in a car, it does not affect its safety and technical characteristics, the manufacturer does not focus on its quality: the main thing is that there are no breakdowns. As a rule, for standard acoustics, equipment is used from well-known companies, but budget options.
The standard system has a narrow frequency range, which gives the listener a plastic sound, the sound has no volume, and at high volume the sound from the vibration of the door trim begins to be heard. Premium cars have quite elite acoustics from well-known manufacturers, so such cars do not require replacement of the audio system.
High-quality sound in a car allows you to convey all the tones of sound, it has volume and strength. Good quality sound is clear, and the door paneling does not ring out. With all the shortcomings, the standard system is very reliable, matched to the design of the car, so if you just listen to the radio in the car, rarely turn on the music publicly, then it is quite possible to limit yourself to the “native” audio system.
The number of speakers in a car is not the most important factor in the acoustics of a car, much more important is its type. The minimum set of loudspeakers should be one pair of two-channel, which consists of a high-, mid-frequency and a crossover filter. The tweeter is placed higher, the midrange ones are lower, the subwoofer can be placed anywhere.
It is important to ensure that the speaker is rigidly attached to the vehicle parts. When buying new speakers, keep in mind that OEM speakers are often smaller than custom ones. Next, you should take into account all the technical components: the resistance is more than 4 ohms, the sensitivity is 92 decibels. All manufacturers of acoustic systems offer various types of acoustics in different price categories: from budget to professional.
Budget options from well-known manufacturers cost about $ 50, premium models can go up to $ 2,000, on order - up to $ 10,000. You should not buy a speaker system of an unknown brand, it will not last even a year, therefore, if there are money constraints, it is better to use a reliable standard system.
