I have an '84 T-bird with speaketrs mounted under the dashboard. The right-hand one is loose (the sound stops and starts now and then), but the instructions in the Chilton manual I have are for an older version of the '84 T-Bird with a partially-removable dashboard shelf. The shelf in my car is all one piece and I have no clue about how to move what has to be moved so I can check the speaker wire.
Any suggestions?
