Jiamen carman car audio car CD question 200

Probably a mechanical breakdown!

It may be like a Panasonic CD: the inlet and outlet discs and the running bald head share a motor, and the mechanism inside is the bite between the gears and the teeth. Unlike other CD players, the two motors go their own way and there are fewer gears!

That is to say, the tooth or gear of the CD bezel does not work, although the disc goes in, the "door" is not closed, the bald head will not work, and the butterfly will not be able to read out normally!

Disassemble the movement, connect it to the main unit with a flexible cable, and power it up to see how it works!

I just wanted to say, is your line connected incorrectly?

The CD has 2 wires.

In general, this is the case.

There are two plugs, one for the power supply and one for the four speakers.

First of all, let's talk about the plug of the power supply, the big red is the 12V live wire, the orange is the memory power cable, and the 12v live wire is also connected to the black wire, the negative antenna, do not do research, and this problem has nothing to do.

The second group is very simple, 8 follow-ups, 4 groups of different colors, 4 speakers each, it's as simple as that, you try to do research, and if the problem hasn't been solved, it's a mechanical failure.

It's really hard to say, go to the audio store and check it out!

Jiamen car audio? There is no value for maintenance, and I threw it directly into the trash can and drove to buy an imported brand machine.

In fact, it is an ordinary CD, but because the noise in the car is relatively large, the listening environment is relatively bad, this kind of CD improves the part that is easy to be drowned by the noise in the car, mainly the low-frequency part, therefore, listening to the car-specific CD in the general audio, there may be a phenomenon of excessive low-frequency weight.

In fact, most of the so-called car-specific CDs are ordinary CDs, but find some with a stronger sense of rhythm, you can hardly imagine listening to soothing**or sad** while driving, and the rhythmic** can make people excited and prevent dozing.
