Basses in the car must be adjusted professionally

A modern car is almost impossible to imagine without a good audio system and decent bass. As a rule, machines of a standard sample can not boast of a good sound, so it is better to do such work yourself. During the construction of the audio system, perhaps the main task is to create in the machine a so-called sound stage, on which the images will be clearly localized and perfectly focused. Usually, the rear location of the subwoofer significantly complicates the formation of sound in the low frequency region . If the wrong parameters are set incorrectly and the wrong frequency is set, the overall melody may collapse, and the sound of instruments with a low and medium range will scatter around the cabin. Can this be avoided? How to make sure that the bass in the car was installed correctly?

The sound theorem

In theory, the simplest method is to install a subwoofer in the front of your cabin. Only in this case the emitter will be located next to the midrange and tweeter speakers, and the alignment of the sound scene will be much simpler. Quite often that's exactly what they do. Professionals perfectly understand all the advantages of this decision. They are even ready to accept some difficulties, for example, a rather complicated process of creating a hull of uneasy shape. However, an ordinary music lover such a task is beyond his powers. Does this mean that we should be satisfied with the subwoofer, which always buzzes and gives out incomprehensible basses to the car? Of course not.

Is there life below 100 Hz?

If you do not want to place a subwoofer in the trunk of a car, then you need to carefully consider what is happening in the car at frequencies that are below 100 Hz, and, of course, just resort to those features of auditory perception that nature has generously rewarded us with. The researchers of acoustics note that in the region below 700 Hz the temporary localization of the sound source is triggered. This eventually leads to the fact that our brain perceives the difference in time of arrival of the acoustic signal to the right and, accordingly, to the left ear of the person. If no such effect is observed, the listener seems to think that the sound source is located directly in front of it, and a sharp increase in the difference indicates a shift relative to the center. This localization scheme works well in the upper bass and in the lower middle.

And now let's consider what will happen when we install the speakers. What bass in the car will the technician give out? During the middle frequencies, sound waves will begin to form . They will spread through the car, will be reflected from the walls of the cabin and begin to interact with each other. As the frequency limits decrease, the propagation of waves begins to decrease. However, let's not go deep into the physics of all these processes, let's talk about more accessible and understandable things.

What should be the case for the subwoofer?

In order for the bass to go to the car really high-quality and deep, it is necessary to pay special attention to the subwoofer case. Specialists in auto sound do not advise buying ready-made and cheap boxes, which are abundant in the markets. These boxes are usually made of very thin plywood, which simply is not suitable for working with powerful low-frequency sound reproducing equipment, because such a case in the process of operation quickly begins to vibrate and rattling. Indeed, a quality box can be built using strong, uniform and hard materials. It is best for this case to use MDF and HDF. Keep in mind that the walls of the shell should have a thickness of at least 2 centimeters, if there is more - this is even better.

The thicker, the better

Ideally, the front wall should reach 70 millimeters, and the side supports - 40 mm. To further strengthen the strength of the structure, spacers between the walls should be used. Acquiring the body, be sure to knock it out. If, in response, you hear a loud response, such a box will not work, but if the sound is muffled, then this is exactly what we need. Feel free to purchase such a case and install it in the car. With it, the bass for your car will be saturated and truly quality. However, this is not all. Keep in mind that such cases can themselves be sources of sound distortion, especially if unsuccessful calculations were made during design.

A little about the cabin

In order to get a good bass, it is not enough to assemble a classy subwoofer enclosure, it is also necessary to correctly adjust the frequency of filter division. An unsuccessful box can become a source of extraneous sound, about the same happens with loose parts that are in the car's interior. Do not forget about this when you are preparing the car for mounting the audio system. Of course, the bass in the car in 2013, that is, in the "fresh", not yet realized what Russian roads are, is easier to install than on a car with mileage. There are fewer poorly fixed parts, more technologically advanced materials are used, so the sound is more saturated and deep.
