I think whether it is a car CD or a home CD, there is a big difference in their quality and **! Furthermore, if you have a good CD, you must also have a good amplifier! Only when the CD and the PA speaker exist at the same time, can there be good sound quality!
It was a treat!! Hehe! Hope to be you! Thank you!

CD player: home. Different from general household CD equipment, it is one of the inherent configurations that are fixed in the car to use the vehicle's battery power.
Cooperate with the in-car audio-visual terminal equipment (power amplifier and woofer, etc.) to provide an operating system with sound quality due to traditional cassette equipment. The main function is to provide the necessary auditory enjoyment according to the needs of the people in the car.
CDs: each has its own good and bad.

There is no difference between a CD in a car and a regular CD. Car CD and ordinary CD requirements for CD are the same, there is no difference, ordinary CD player can be the best CD, in the car CD player can be the same. Explain that they work exactly the same.
It's just that the car CD pays more attention to the smoothness of the CD operation, the tracking ability of the laser head and the disk reading performance, so its ** is higher than that of the general CD player.

On the surface, the *** disk is very similar to the CD VCD disk. But in essence, there is an essential difference between the two. If you think that the difference between *** and cd VCD is only in the ** effect, it seems a little too simplistic.
1. From a technical point of view.
CDs are all the same because they store the required data in a tiny groove in the disc track, which is then read by the laser beam of the optical drive. However, in terms of the density of optical discs, *** is much larger than CD, so when reading *** data, a shorter wavelength laser beam is required than when reading CD data. Because only in this way can the laser beam be focused and positioned on the disc more accurately.
The minimum pit length of CD is and the channel spacing is used to read the data with an infrared laser with a wavelength of 780 790nm, while the minimum pit length of the CD is only and the channel spacing is used to read the data with an infrared laser with a wavelength of 635 650nm.
2. In terms of data capacity.
CDs can only hold around 650MB-700MB of data, while *** can hold the least amount of data. According to the various combinations of single-sided and double-layer structures, it can be divided into four physical structures: single-sided single-layer, single-sided double-layer, double-sided single-layer and double-sided double-layer. The capacity of a single-sided, single-layer*** disk is about 7 times the capacity of a CD ROM, and the capacity of a double-sided, double-layered *** disk is up to 17GB (about 26 times the capacity of a CD ROM).
Single-sided *** disks may have one or two recording layers. As with CD, the laser reads the data on the single-sided disk from the bottom of the disk, and the data on the double-sided *** disk is stored on the upper and lower sides of the disk.
3. In terms of function.
It can provide a variety of features such as multi-audio tracks (multi-language), multi-text support, and multi-angle viewing, which are not available on CDs.
The difference between *** and cd is roughly like this, although it seems relatively simple, but just a few differences are enough to make *** completely defeat cd, but because the latter two are currently relying on their advantages in the world, they still have a high advantage in the market, but I believe that in the near future, *** will officially replace cd to become the absolute mainstream.

The selection and use of car CDs are as follows:
At present, the main brands of CD players are: Clarion, Alpine, Pioneer, and Kenwood.
In addition to choosing a brand with reliable quality, the second thing is to pick your favorite songs.
Then according to the model of the car to choose the suitable CD, CCD types are very many, there are single disk, three disks, six disks, eight disks, ten disks, twelve disks and so on.
When installing the single-disc machine, it should be noted that it must be installed horizontally and fixed firmly, otherwise the shock absorption effect is poor, and the laser head is often protected when it is vibrating, which will make the CD player aging for a long time.
CD machine should be adjusted before installation of the shock absorption direction knob, otherwise there is no shock absorption function, or even damage to the CD machine, the multi-disc machine should first pay attention to the connection line between the host and the CD machine during installation, in order to prevent interference with the power cord on the car to separate the wire, and to take the original line.
Try to use genuine discs, because the reproduction CD disk is poor in the production process, and the product often has uneven disc surface and uneven pitting etching, and these hidden dangers will cause the reading speed of the bald head to not keep up with the jump point, so that the sound is intermittent, and the bald head will be damaged for a long time. In addition, users should clean their hands when taking the disc to prevent oil stains and secretions on their hands from contaminating the disc surface. When wiping the dust on the disc surface, wipe it along the perpendicular direction to the trajectory, and wiping along the trajectory will damage the disc.

The car disc only needs to open the co-pilot's glove box, put it in the long reading area, and finally push it in by hand, but only when the vehicle is powered on. Start the disc when the car is running normally, turn off the disc before parking and turn it off, or turn down the volume.
1.First of all, it should be noted that it is necessary to use genuine discs as much as possible, because the production process of pirated discs is poor, and the surface of the product is often uneven and uneven. These hidden dangers will cause the optical head to not be able to keep up with the jump point when reading at **, and over time will make the sound intermittent and damage the optical head.
2.In addition, users should clean their hands when picking up the disc to avoid contamination of the surface of the disc by oil stains and secretions on their hands. If the bald head reads the surface of the disc with contaminated surfaces, the sound quality will be affected.
When the laser head is covered with dust, the light transmittance of the optical head will be greatly reduced, which will make the reading effect worse, and the speed cannot keep up with the failure, so try to avoid dust entering the CD** machine when using. When driving on bumpy roads, it's best not to use the disc **. If there is a Chuck failure, don't do it yourself without being absolutely sure that you won't magnify the failure.
The most common is laser head dirt, usually dust. Treatment: Spray with a spray ball.
At present, the cleaning discs on the market can only do a slight cleaning, but they cannot completely solve the problem. If the laser head is contaminated with moist air, it should be cleaned with a detergent. If you use mechanical parts for a long time, you should also clean and lubricate them.
Millions of car purchase subsidies.

CD player in the car.
Can be used at home. But the dish player at home. There are almost no things that can be loaded into the car.
The disc players on the car are all specially designed, and special processing has been done in terms of shock absorption and data reading.

There are two kinds of car CDs I don't know which one yours One is able to recognize *** format** file If it is this kind of car CD, it is better You can find a blank CD and directly engrave ** into the general CD capacity is 700MB It is recommended not to engrave it full Keep it at 650MB Generally you can save 100 to 200 songs** If your CD player is not able to recognize ***** then it is recommended that you burn it with Nero's software Generally, Nero can directly generate CD format** As long as you find the corresponding *** file before, there is an option to burn** After choosing, you can directly choose to burn** disc So that you can add your *** file according to the steps Generally, the total length should not exceed 70 minutes Finally, choose to burn You can make a **CD If you don't understand anything, you can leave a message It is generally recommended to use nero7 It is easier to use.
While CDs generally only have sound signals, VCDs have both sound and video functions. At the same time, we can see the difference between CD and VCD, all the channels of the pure CD head are for the sound, and most of the channels of the VCD head have to be given to the image. Therefore, the sound effect of **CD is better when choosing a CD player with a pure CD bald head. >>>More
If you are burning **CD, use burnatonce, a top-notch **burning software, small and compact (only a few M), simple and easy to use, good reputation, and excellent sound quality for burning CDs. It also supports burning data, mirroring files, duplicating discs, and saving discs as images, but only CD-R. >>>More
Use a medical cotton swab dipped in absolute alcohol and wipe the laser head. The laser head is dirty for a long time and cannot read the disc.
1) Do you have to use a CD disk, or a *** disk?
It depends on the CD player in your car. I learned from Autohome that the new Bollywood should be CD support*** WMA, *** no. i.e. your cd player can be a traditional cd disc, or your own, wma and then burned in cd. >>>More
