Hi all i've found one drivers side speaker is not working (middle one).

 

I'm trying to find out if the 3 speakers in the drivers door use the same audio wiring feed or do they have there own separate amp feed. if they use the same feed it would be a simple wire/speaker fault find as the other two are working fine. however if they have there own separate amp feed it could be an amp fault.

 

XF Face Lifted

Bowers & Wilkings 1200w system

 

any ideas?

Thanks

 

Ian

Ian,

 

Don't know the answer i'm afraid .

 

Bowers and Wilkins are highly regarded . Your car cannot have been long out of warranty, it might be worth giving the dealership a ring as Bowers and Wilkins might have their own warranty on the audio system .

 

It might be worth getting in touch with them also .

Thanks for your reply Trevor. Not that happy with my stealership At the moment. I'll have the door card off at some point and post my findings.

Ian,

 

Most of the stealerships are dire, mine was so bad, as was Jaguar themselves , so I bought a Mercedes

5 Months to get my car booked in for a thumping noise then took 7 days to say it was a bad tyre. Shocking

Ian,

 

Took mine in, they said they didn't have the part, and neither did Jaguar, and couldn't get it until after Christmas .

 

Told them I didn't pay £50K for a car for it to be stuck in the garage for weeks, so I sold it .

 

ATB,

Don't get me wrong I love this XF it has all the bells and whistles but I think it will be my last Jag.

Ian,

 

Same here. Tried my very best, but Jaguar really don't do themselves any favours .

 

They weren't bothered in the slightest when I told them I was going elsewhere because their customer relations are very poor .

 

ATB,

Ok so I found some time to remove the door card as I also wanted to sort the common door rattle. I could not see anything wrong with the speaker wiring so continued to fix the rattle.

After refitting the door card and reprogrammed the auto window thing, I found the speaker now works.

Solved

After this speaker stopped working again I did some fault finding and found something that led me down the garden path so its share time

When the system screen boots up I was getting a small fizz for half a second from all speakers including the non working speaker. This told me the speaker must be connected to the amp.

I found the below wiring diagram and unplugged the multiple plug, I then used a tester and found the resistance on both working and non working circuits to be the same 2 ohm. I then swapped the two speakers over and found the speakers are fine.

Must be the amp I here you say

Errr no!

I then removed the wires with there pins from the multi plug and swapped left with right as to move the fault to the other side.

You guessed it the fault remained on the same side.

I then came to the conclusion that even though the resistance of the two circuits read the same it could only be the wiring.

Bingo running a new cable solved the issue and no longer get the fizz sound on screen boot up too.
