There is no sound from the audio speakers (left & right) which are located in the front doors.
All other speakers in the car are working fine. The balance level on the radio (HU-415) is properly adjusted. There is no front/rear fader.

I am not sure if it is the speakers that are blown, contacts that are finished or something in the wiring.

Has anyone experienced this issue or have any suggestions on how to resolve it?

I thought originally it was only the left door speaker not working and wanted to test the wiring with the right door speaker. I attempted to remove the right door speaker, but saw no sound from that one also.

Your advice/suggestions are appreciated.
Thanks
