- Blown fuse: Check the fuse box to make sure that the fuse that powers the stereo hasn't blown.
- Broken speaker wires: Inspect the wiring inside the door panels and trunk. Make sure there aren't any loose or frayed connections that could cause the speakers to stop working.
- Faulty amplifier: If your LHS has an amplifier, it could be faulty. Try disconnecting it and see if the speakers work without it.
- Head unit issue: The head unit, or the stereo itself, could be faulty. If you've checked all the above and the speakers still aren't working, you may need to replace the head unit.
If you can't find the cause of the problem yourself, you can take your car to a car stereo installer or automotive technician for diagnosis and repair.
