How to change the car stereo? How to replace a car stereo?

Tune the anus to the starlight.

The car audio is divided into a set of speakers, coaxial speakers and subwoofers. The set of speakers is divided into two-way horns and three-way horns. The two-way speaker is the treble + mid-bass + crossover, and the three-way speaker is the treble + midrange + bass + crossover.

The coaxial horn is that the treble and the mid-bass are on the same axis, and the point sound source is called the coaxial horn. The subwoofer is generally more than 8 inches, and the diaphragm is very large, which is used for low-frequency sound.

The location of the installation is determined according to the different models of the installation, according to the performance of the sound field, generally speaking, when the audio is modified, the set of speakers is installed in the front sound field, and the coaxial speakers are installed in the rear sound field. So how do you install the tweeter in the front sound field? Like some Nissan series models and Honda Fit models, the original car does not have a tweeter, so when modifying, you can make an inverted mold or make a hole in the door panel to install the tweeter.

The most standard and best positioning is to put the tweeter on the A-pillar or the triangle position of the door panel (like Mazda M5, M3) The coaxial speaker of the rear sound field is directly installed in the position of the original car audio, and the best installation position is, of course, in the rear door panel position, like some models, the original car is in the rear partition position, such as Civic, Camry, then it can be installed in situ, or the rear sound field horn is installed on the rear door panel. If you want to save space, then make an inverted mold, and install heavy bass according to the space of the trunk.

A set of sound with good effect, equipment matching is one thing, installation is also one thing, and debugging is also one thing. If you just generalize how to achieve the effect after the audio modification, you still have to position it according to the model, according to your own modification budget, and make reasonable and appropriate modifications according to your own listening style.

1.First of all, you need to disassemble the door panel of the vehicle, replace the horn, if there is a horn on the workbench, you need to replace it with a tweeter, if there is no horn, you need to install a tweeter, install the amplifier system in the trunk position or under the co-pilot seat position, and install a subwoofer in the trunk, which will have a very good effect.

2.Including power amplifiers, peripheral equipment (including limiters, effects, equalizers, VCD, ***, etc.), speakers (speakers, speakers), mixers, microphones, display equipment, etc.

3.Among them, speakers are sound output devices, speakers, subwoofers, and so on. A speaker includes three kinds of speakers: high, low, and medium, but not necessarily three. The development history of technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect transistors.

If you open the speaker settings directly, the speaker switches of the four doors will be displayed, and you can just click on it.

Due to the limitations of the use environment and conditions, home audio is not suitable for modification to use in cars.

The main reasons are as follows:

1. The power supply mode of the system is different, the car is generally a single 12V DC power supply, while the home audio is 200V AC power supply, in order to use the push-pull power amplifier form, even the DC power supply inside the audio will be powered by positive and negative power supply. In addition, the power supply environment of the car is more complex and harsh, and the power supply system of the car audio has higher anti-interference and redundancy capabilities. Therefore, the power treatment of converting home audio into car audio is very complicated.

2. Car audio is used in car sports in some cases, and environmental noise becomes the main killer that affects the sound effect. The main feature of home audio is to ensure that the output sound signal is restored to the original sound as much as possible. Therefore, from this point of view, home audio is not suitable for conversion to car audio.

Here's how: Step 2:

Then let's turn up the gain of channel-1 2 until it's loud, or the maximum sound you can accept, then we turn down the volume of the console, put in a vocal disc or a disc with stronger low frequencies, and then slowly turn up the volume of the console until it is slightly louder than you can listen normally.

Step 3: Sound insulation and shock absorption is a means of slag, and we can reduce the probability of this sound through the crossover (cut-off frequency) on the main engine or power amplifier.

Step 4: The next step is to adjust the rear sound field, no matter what state the front sound field is, the rear sound field should be set in the HP shape such as the medium state.

Step 5: The adjustment of the bass is a key to the car audio, and a good adjustment will make the sound guess turn upside down.
