How to choose the best place to install the speakers in the car?
When choosing speakers for cars, guided not least, it is necessary to features of their placement in the vehicle cabin. Since the installation, you may have to carry out some interventions in the interior. Many vehicle manufacturers are factory equipped their cars speakers, or allocate them special regular places where I can then install the speakers.
However, even if the speakers in the car already, you do not always satisfy the car owner. He may not like the type of sound and acoustics in the cabin accommodation. Therefore, they seek to replace the regular speakers for more powerful and sophisticated models to achieve a better and sound quality.
How to choose your seat to install car speakers?
To get a good sounding audio to the car interior is recommended to install at least 4 speakers — Two front and two rear. It is important to remember that the front speakers are of lower quality than the rear. This is due to the fact that the front speakers account for a large load, and they are responsible for creating the front stereo pair. Of course, if you put more speakers, the sound will be more realistic and vivid. For example, in this 4th add a stereo pair in front and in the rear doors.
Note that this is true only for those cases when additional channels are the same quality as the core. Otherwise, it just would not make sense, and only just wasting your money. If we deal with the acoustics, the right to do everything necessary to qualitatively and not skimp on equipment. Especially if it is very important for you to achieve the perfect sound.
Where in the cabin of the machine can be installed speakers?
To create an effective sound system inside the car have a few options:
- First — increase the number of speakers. This solution is quite popular, so it does not require any complicated manipulations or calculations.
- The second — use high-end component of high power loudspeakers. Installing speakers proven and reputable firms (Focal, Morel, Hertz, Rokford Fosgate et al.), gives an opportunity to get an excellent playback quality.
Also note that in any case, no matter what option you choose, be sure it is recommended to add to the audio one and ideally two subwoofers. This will make it more saturated bass and makes the sound richer and more powerful.
Of course, it will cost a lot of money, but can also cause some inconvenience. For example, you need a powerful amplifier (or amplifiers), line-out on the radio, which does not affect the adjustment of the front/rear. If not available, then you will need to use an active crossover. In addition, for the installation of all of this wealth must still find a place in the cabin: where to mount the speakers, which deliver power, and where to place the subwoofer, etc.
EXAMPLE standard arrangement of acoustic elements of the system inside the car
Find a place to install coaxial speakers easier. But here, it is recommended not to forget about some features of their installation. Indeed, except for the frequency response of each speaker is also directional characteristics. For example:
- low-frequency sounds (less than 200 Hz) can propagate well in either direction, they are not easily fear obstacles and their envelope.
- midrange sounds (from 200 to 400 Hz) have a property such as absorption, for example, backs of chairs, etc. However, they are clearly focused, although they may go around some obstacles inside the machine.
- high frequency sounds (above 4000 Hz) are transmitted almost in a straight line, they do not create the stereo effect. Therefore, it is recommended to use separate tweeters, who are best placed in front of the cabin. Direct radiation is necessary so that the axis of the speaker fell in a region of people's heads in the front seats, a first reflected sound, and then already passed in the right direction.
Features speakers mounted in the front panel
As we have mentioned before, the sound quality affects the location of the front and rear speakers, and subwoofer. It is important to understand that all the speakers creating a certain sound field. And on their orientation relative to the listener, will depend directly on the sound characteristics. Low-quality speakers or installation errors lead to the fact that the sound turns out blurry, and it is impossible to properly adjust the sound stage.
The sound stage in perfect speaker should be placed at eye level in front of the audience. It goes beyond the boundaries of interior — so it seems that the sound sources are also still on the hood, are distributed across the width and depth. Correctly chosen location affects the purity of the sound. It is very important that there is no non-linear distortion, tonal imbalance. All tools must be legible, ie, sound waves do not interfere and cause interference.
A few nuances that are important to consider when installing and configuring the speaker sound
In the formation of the audio system is very important front speakers. These dynamics play a major role. For stereo highest priority are medium and high frequencies. At the same time, it is obvious that in the front are not very many places where you can set the CH/bass speakers. Typically, they are placed on the dashboard or in the front doors are sometimes used space at the bottom side from the front panel.
The measurements show that the installation of speakers in the front doors, provides for the driver and passengers the optimal balance between sound in the low and high registers. This option is preferred over the installation in front of the speakers.
Unfortunately, most of the regular places that were identified by speakers at the factory, not the most successful, is acoustically unsuitable space. Most often, the plastic niche, but it is not the best material. At low temperatures it narrows fastening elements begin to experience increased load. In the worst case, cause the plastic parts resonate with vibrations of the diffuser, which negatively affects the quality of sound transmission, since the interference created.
To increase the reliability, it is recommended the available installation space strengthened through special metal inserts. Moreover, not prevent perform additional processing of the acoustic space in which the speaker is mounted. For example, when mounted in the front doors are a very good option is to use special additional patch pockets, the required volume. This will help ensure the correct acoustic design that will increase the efficiency and acoustics make it more clear and accurate bass response.
There are many options for placement of the car speakers in the front doors. The sound quality will be immediately affected by the distance to the audience, and the mounting height and the direction of radiation and the distance at which between them are high frequency and mid/bass head.
The rear speakers are designed to add bulk, fullness of sound. They also help the passengers who sit in the rear seats easier to hear music as sound up front they can not reach the full. Rear speakers often mounted in the rear shelf. Rear speakers are better suited for use with low-frequency sounds.
Features of sound ratio speaker settings in different areas of interior
It should be remembered that the sound field during playback in the cabin of any car — a combination of two fields: the front and rear. That is, in any case, the sound waves are superimposed on each other. And here it is important to keep a balance, because the delay signal from the rear speakers can spoil the whole picture. Back field must be non-intrusive, it merely adds to the overall picture, making it brighter and more saturated. That is why it is important to always use the subwoofer. Without it difficult to achieve a good bass, a subwoofer is required to provide bass support for all audio and surround sound will be more uniformly dispersed in the space of the automotive interior.
The most ideal option to configure the system so that the volume ratio of the front and rear of car speakers and subwoofer are not caused in the listener the impression that the sound comes only from the next speaker. Sound should fill the entire space. In this case, you can achieve high-quality and clean sound that give you pleasure and will not tire on the road. To adjust the sound processor can be used, or a modern radio, which has ample opportunities for setting and adjusting the sound, including the ability to control sound delay.
