Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada kuasa | Blown fuse, incorrect wiring, loose power connection. | Check inline fuse, verify +12V, GND, and REM connections. Ensure connections are secure. |
| Tiada output audio | Incorrect input selection, loose RCA connections, amppenguat tidak dikuasakan. | Verify Input Select switch position. Check all RCA connections. Ensure amplifiers are powered on. |
| Bunyi herot | Input level too high, output voltage mismatch, EQ settings too extreme. | Reduce head unit volume. Adjust Input Level and Output Voltage switches. Reset EQ bands to flat and adjust gradually. |
| Engine noise/hum | Ground loop, poor ground connection. | Ensure a clean, secure ground connection. Experiment with the Ground Isolation switch (200Ω/GND/ISO). |
| bass lemah | Digital Bass Processor level too low, Subsonic filter set too high, EQ bass band reduced. | Increase Digital Bass Processor Level. Adjust Subsonic filter to a lower frequency or off. Increase 50Hz EQ band. |
