Sounds like you could have an issue with the factory amp or it could be grounded out wire on one of the speakers.
This car comes with "Smart amp", Which can monitor the output to the speakers. And if one of the speaker goes out it can cut power to all of them.
Try disconnecting one speaker at a time to see if the sound comes back on. That way you will know the faulty one.
I have also included the wiring diagram for your reference.
Please let me know of any questions.
