What could be the reason for a sudden loss of sound in a Nissan car audio system?

Nissan car audio suddenly not working may be due to abnormal CD player power supply, fuse failure, speaker malfunction, and other reasons. Abnormal CD player power supply: Check if the CD player's power supply is normal. When there is power, the indicator light should be on, and the CD player compartment should be able to open and close normally. Fuse failure: If there is power, consider whether it is a modified audio system. Check if the modified fuse has failed. If not, check if the audio output line has come loose. Speaker malfunction: Car audio systems, whether in terms of sound quality, operation, or shock resistance, have reached a high standard and can handle the bumps of a car on rough roads, ensuring stable performance and perfect sound quality. Therefore, the possibility of speaker malfunction is low, but it cannot be ruled out without inspection.
