speaker problem

Went to fit some fli speakers today, passenger side is working fine, drivers sides not working, tried the original, and that's not working either :s any ideas anyone? I cut off the original connector to splice the wires into the speaker, my wiring is sound and I know the speakers work....
 
Sounds like a broken cable, the girlfriends is the same, have a suspicion that it will be part of the cable in the door joint, (open and closing often can fatigue it or wear it), but easier to check the connections behind the head unit.
