Can't hear the speaker

[Mountain Aire III]

We have a 40' MountainAire DP.
The speakers in the coach have a mind of their own. The two speakers in the bedroom work fine but the two passenger side speakers up front don't work. Durning our travels over rough roads the speakers come to live for a brief period. I have checked the connections at the radio and found them to be secure. Clearly there is bad connection somewhere. I have tried to follow the wire to the speakers but have not been successful. I even tried removing the electrical panel by the front door to see if I could get to that front speaker and check its connection but have not been able to access it. Has anyone experienced something similar? Any suggestions would be appreciated.

If you have over head fans open the panel in rear of cabinet. In there you will find all this wiring. Has speaker wiring, clearence lights up front and other wiring which is marked on each wire as to where it goes like spk left rear bedroom and so forth.


This pic shows the passenger side spk which multibles to the passenger side spk in kitchen. The spk's have wire clips attached to them front spk will have two wires connected on clips. Drop spk in kitchen by removing grill and screws holding spk to check. There are wire nuts in the wiring mess location.
