Door speakers stopped working

[Guest]

Hi all,

Just recently the mid and tweeter speakers have stopped working on drivers side. As soon as I enter the vehicle you here a couple of second crackle from the mid speaker, it stops and then neither the mid or tweeter have any output? The woofer is fine! I have removed the door card and wiring seems fie, no visible nicks or damages?

Is the tweeter speaker linked off the mid?

Any ideas would be appreciated 

Thanks..
