Dreams of clear and surround sound in a car are easy to realize. All that is required of you is to have a minimum amount of knowledge about acoustics, correctly select the main elements of the system and decide on the location for their installation. We will pay attention to these aspects in the article.
Types of speakers for cars
Any speakers intended for use inside a car belong to one of the following types:
The quality of music reproduction in speakers of this type is much higher, but at the same time they have a significant cost. Two and three-component columns. Component acoustics are available in two- and three-component versions. The first type of device consists of several low-frequency speakers and a tweeter. Three-piece speakers have two additional tweeters that control the low and mid frequencies. Three-component speaker systems provide the highest sound quality.
Acoustic screen in the door
The screen is most needed for speakers with high and mid frequencies. The main purpose of using the screen is to provide the clearest and at the same time deep bass. The optimal playback range for such a speaker should be at least 50Hz.
There are two options for acoustic screens:
- Internal - the material is installed under the door card;
- External - a special box is made in which the loudspeaker is located. It is attached on top of the door card.
Each option has its own advantages and disadvantages.
Connect the amplifier to the car
To properly organize sound in a car, you first need to understand the types of subwoofers, amplifiers and the location of speakers, and then choose the correct connection diagram and correctly lay out the speaker wiring. Stories from our readers “Fucking basin!!! Otherwise, it becomes necessary to treat the inner surface of the interior door trim, the inner surface of all plastic parts, the inner surface of the ceiling, the roof of the body, and pour damping liquid into the mirror with vibration-damping materials. Speaker bands - speakers, acoustic system, acoustics - the number of speakers in the acoustics, which each reproduce their own frequencies.
Accordingly, it is physically unsuitable for wires. The simplest design with no air holes. A significant portion of high and bass frequencies are not transmitted, and the natural overtones of musical instruments are lost. All amplifiers are designed to operate with a certain load impedance. The amplifier may have a certain class: AB and D. The wires going to the speaker systems should not be parallel to the power cables. It turns out that the influence of the door on the performance of the midbass can be neglected, and the speakers should be chosen from some well-known company - the more expensive, the better. If it does not decrease, but increases, then the polarity of connecting one of the speakers is not correct.
A two-coil subwoofer, as well as two, three or more subwoofers, can be connected in four ways: each coil separately, parallel connection of coils, serial and combined. When connecting from a radio, there is no point in selecting speakers by power. In principle, there is nothing complicated about this, but due to ignorance or in a hurry, you can make an incorrect connection, at best the system will not sound right, and at worst, failure of a component or the entire system. Typical car audio system circuits: two-way (two-way audio system)
Installation of car speakers
In household speaker systems, the right and left speakers are usually located at the same distance from the listener and approximately at the level of his head. It is unrealistic to meet such conditions in a car, therefore, when installing a component speaker, the need to achieve possible approximation to the ideal comes to the fore.
Speaker placement options: where to install speakers
It was experimentally established that for front acoustics, the optimal placement of speakers is on the edges of the dashboard and the adjacent part of the A-pillars. In this case, you need to ensure that the speakers are brought forward as far as possible.

Experts also advise placing speakers of different frequencies belonging to the same channel in close proximity to each other. This will ensure sound integrity and consistency. The speakers can be oriented in opposite directions: one should be directed at the driver, the other at the windshield of the car, so that sound waves are reflected from it.
Unfortunately, large speakers are difficult to place along the edges of the dashboard. Therefore, many car owners choose a compromise option.
It makes sense to place the woofers and midrange speakers in the lower front corner of the door, and the tweeters on the A-pillar or in the same corner of the dashboard. This scheme provides acceptable sound quality with less time and money.
Only the most desperate music lovers will appreciate such a creative option for placing speakers on a car door.
Internal acoustic screen
Pros:
- There is no need to damage the door card, which preserves the interior of the car;
- All elements of the internal screen are hidden under the casing, so there is no need to perform any decorative work for the speakers to not only sound beautiful, but also look decent;
- A powerful speaker will be held more securely, which will allow it to be “swinged” more strongly.
