Why is there no sound coming from my JVC KD-G401 speakers?
- M
  Mackenzie BrownAug 23, 2025
  If you cannot hear sound from the speakers, there might be a few reasons: * The volume level might be set too low. Try adjusting it to a higher, more audible level. * The connections could be incorrect. Double-check all cords and connections to ensure they are properly connected. * The built-in microcomputer may have malfunctioned. To resolve this, reset the unit by holding the SEL (select) button and pressing the (standby/on attenuator) button for more than 2 seconds. Note that this will erase the clock setting and preset stations stored in memory.
