Hi Guys just found this great forum and in desperate need of your help please.

Fitted a aftermarket pioneer headunit from a CD 6000 a number of years ago and its been fine but a few weeks ago i lost the sound from front and rear speakers and there is only sound coming from the the front door tweeters. i tried connecting a seperate speaker direct from the back of the pioneer HU and there is sound and after a quick google im led to believe that it points to the audio control module but  i have no idea if my 2009 has one of these and if it does where i will find it?, i have had the radio out as some say it is in the dash somewhere? but cant locate anything obvious.

Ive now fitted a new headunit but it still has the same issue

can anyone help please guys

I'd start by testing the actual door speakers, they have a track record of total failure on your model. Many here on the forum have had to replace all of the speakers.

I think there are a few threads about the door speaker replacements on your model. @StephenFord might remember more details, or even the thread.

Sorry @unofix, I normally do bookmark threads of personal interest, but this issue doesn't make me lose sleep. Since I got my car 4 years ago, the rear speakers have never worked. It's never worried me as I only ever listen to 'Talk' radio. However in recent months, my driver door speaker has been troublesome leaving me down to one speaker, however, a darn good slapping on the speaker grill makes it burst back into life which will last anything from an hour to a month!

Years ago, this would have irritated me intensely, but I'm old and much more chilled out now, I treat it as a delightful Focus quirk 🤣

On reading the OP, losing all 4 x speakers simultaneously does seem to point to a fault elsewhere from the speakers, you'd have to be the unluckiest guy on the planet to get 4 x faulty speakers at the same time, but I guess not impossible if there has been some overload issue.

The audio control module (or ACM) is the head unit.

The speakers are direct wired from the head unit.

I would suggest either broken wires somewhere or the speakers all blew at the same time (which I doubt)

Direct connect a speaker wire to each speaker to prove out

@DaveT70@StephenFord@unofix many thanks  for such informative and quick  replies.

 

well i went out today after a  few days busy working to finally take a look at the door speakers but bizarrely when i put on the spotify the drivers door speaker worked normally! 

the passenger door main speaker still doesnt work just the tweeters in the front doors, still no sound to the speakers in the rear doors.

Did a quick inspection in the rubber grommits to the doors with nothing obvious, do all the door speakers go to a main wiring loom or should i just take of each door card in turn to see if theres any output getting as far as the speakers?

as @StephenFord says above be unusual for all speakers to fail together but thinking about it recently the drivers one had developed an annoying vibration no matter how loud i had it.

 

Thanks again guys for your advice

One time I had Halfords doing my MOT and with all the extra checks they do there they done a battery check and when I got the car back I had that exact issue the music was only coming from the tweeters. I disconnected the negative battery terminal for 5 minutes and put it back on and all speakers came back.

Yes. Try a 'reboot' of the cars systems by disconnecting the battery leads and either leave for 45 mins or short the leads themselves Not the battery terminals. 

If that doesn't work then each speaker needs testing individually which means, yes, taking  off all the door internal panels. 

Do you still have the original 6000CD head unit?

This unit has a built in speaker test function. Temporarily refitting it would be far easier than taking all the door panels off.

Simply switch the unit on, and hold down buttons 3 and 6. This should then play a low and high tone through each speaker in turn. The radio display shows which speaker it is testing.
