1. Troubleshooting for Speaker Basic inspection of speaker Inspect the sound from speaker after verifying that the speaker mounting screws is removed and the wiring connector is connected precisely to remove vibration transmitted from body trims and surrounding parts. Case Troubleshooting No. Case Inspection/Remedy 1 Trembling sound Before replacing the speaker, inspect that the mounting screw is installed normally. After re-installing the speaker, verify that no trembling sound is heard. When hearing a trembling sound again, replace the speaker with new one. 2 Noise Check if the wiring connector is connected normally. If not, reconnect the wiring connector. In case of radio static, check if there is a noise from CD. If a noise is heard with the radio and CD on, replace the speaker with new one. NOTE: In case there is only radio static, this causes from poor radio reception. Thus the speaker needs no repair and replacement. 3 Speaker in operative Inspection of the wiring connection between the battery and the speaker Before replacing the speaker, inspect the wiring connection between the battery and the speaker is normal. Check the supplying power to the speaker and the resistance, then inspect the sound quality. Specified impedance: 4 ± 0.6ohms (Scheme 15): Checking Supplying Power To Speaker And Resistance If the speaker works poorly, replace it with new one. CAUTION: When handling the speakers, do not damage the speaker with impact, Like drop or throw. Be careful not to cover water and oil over the speaker. Caution during handling of speaker because the material of diaphragm is paper which is easy to be torn by impact and external force. Modifying the audio system may cause damage the speakers.
