1, often wipe with a moist cotton swab
The pinch roller of the cassette player in the audio and the head of the cd player are places where dust is easily accumulated. The most important part of the cd player is the laser head. Because the laser head is a fragile part and is expensive, it should be focused on curing. Although some car audio systems are currently considered to be dust-proof during the design process, protective measures are also necessary. You can often wipe the cassettes, cassettes, and disc slots of the cd machine and the panel of the sound system with a moist cotton swab. The correct way is to gently suck the dust down with a damp cloth. As for the cleaning of the buttons and knobs, the cotton swab can be used again.

In addition to keeping the main unit of the audio clean, tapes and cd discs must be clean. The dirt on the tape and the disc not only affects the sound quality of the playback, but even damages the sound. When the laser head of the cd machine is running at high speed, if it encounters dust, the laser head will deviate from the original laser track, causing distortion of the sound and causing damage to the laser head. It is understood that tape and disc cleaning tools are available in most video stores.
3, slow release disk less change
Spring is a high-risk period for car audio laser head damage, because the climate is dry and it is easy to generate static electricity. When you put the plate, it is best not to touch it directly with your hands. Do not take the middle. Slowly put it in. Try not to change the plate frequently. Try to light it when you put it on the plate.
4, the volume should not be suddenly put to the maximum
In the use of the audio, avoid suddenly turning the volume to the maximum, so that the horn coil will burn, which will affect the power amplifier. The sudden increase of the amplitude will also burn the power amplifier.
Common malfunctions
Due to the use of the environment, it is generally difficult to achieve the same level of home audio effects. In the process of use, it is more prone to some faults than the home audio. Here are some common car audio faults and troubleshooting methods.
1, the sound of the left and right channels of the sound is not the same
Troubleshooting: First check if the host balance button is in the middle position, then check whether the front and rear input and output left and right level control buttons are the same, and whether the left and right channel settings of the amplifier input sensitivity are the same. If still can not be excluded, the host signal line can be If you adjust the left and right, the side with the smaller speaker position will become larger. If it is, it means that the host has a problem, and vice versa.
2, a channel treble silent
Troubleshooting: First check if the wiring of the splitter is turned on, then use the meter to measure the sound from the splitter end. It may be wrong to connect the speaker cable input to the bass output.
3, loud noise
Troubleshooting: Check if the negative terminal of the rca signal terminal is turned on. If the negative end of the rca signal output terminal of the host terminal has been disconnected, it can be measured by the meter, and the negative terminal is connected to the host chassis.
4, the volume is large and small
Troubleshooting: First check if the contact between the power ground wire and the car shell is loose, and then check whether the input and output rca of the front and rear stages are normal. Finally, check if the sensitivity knob is normal.
