So I think I found the reason the front door speakers not working... they simply aren't there!
Taking the door card off completely showed the wires glued on the door behind! Only issue is these have no power to them, tried a 6x9 speaker which is big but I had one to hand and nothing from it. I checked continuity from the amp and there is continuity.
What could be the cause for no power, amp not putting anything out? What is the output of the amp too, I plan on getting some speakers but not sure what output the amp gives.
