I'm having some problems with the speakers on the passenger side.


The rear passenger door
And the front passenger door (excluding tweeter)

If I crank the volume up it starts working.

Is this a common speaker problem or a loose connection in the door ?

Thank you


Dec'17: found twisted pair of green wires, chaffed to metal
under the rear mount of the front P seat.

looks like heading for the front door.
Hopefully that's it.
