Front Left and Right Door Speaker Fault - No Sound

Hi, I seem to be having an issue with my front left and right door speakers (mids and tweeters) on my newly purchased car. They have never worked and this today has been confirmed on VCDS (log below, subwoofer is working fine). I know in the past that one of the rear doors was replaced but all speakers are working fine on this rear door.

I have a few questions:

Are the front door speakers connected to a amplifier or directly to the head unit?
Could the amplifier be causing an issue?
Can i remove the grill on the door card or does the whole door card need to be removed?


Any ideas would be greatfully appreciated.
