I have a 2007 Focus with a 6000CD fitted.
The sound is only coming out of the Front Near Side Speaker. The other three are dead!!
I have swapped out the head unit for another and there was no effect. I have checked the ISO plug and all seems fine, its still the original ford ISO harness.
The strange thing is that last week we had a really hot day and then all 4 speakers burst into life for a day. Now its back to output from one speaker again.
Ive not taken off the door cards as I cant see that 3 speakers would have a loose connection.
Any help appreciated.............
