FernMTL,

 

ANC has really nothing to do with the speakers.  ANC is connected to those three mics in the ceiling. 

There maybe 4 wires running to one speaker, or really one door.  I cannot say for sure on yours since you have a different system, but on mine where I had four wires, the front doors I believe actually did have four wires, two for the woofer and two more for the tweeter, the back doors were a little different and maybe how your fronts are where there is four wires connected to the woofer, but two of them actually go from there to the tweeters and there is no separate (tweeter) wires from the head unit or amp.  Clear as mud?

Actually, the ANC has every thing to do with the speakers.

 

Copied from a Ford document.

 

Active Noise Control

 

What It Is 

• A feature of the 2.0L Atkinson-cycle I-4 engine that helps reduce, or cancel, low frequency noise produced by the engine due to vibration at low rpms (1000-1500 rpm), such as when at idle or in gear 

 

How It Works

• Microphones in the vehicle interior headliner detect and measure the amplitude and phase of the engine noise sound waves 

• This information is relayed to the active noise cancellation module 

• The module takes into account engine speed to calculate the target frequency that needs to be cancelled, targeting only unwanted engine noise and not      other noise inside the cabin such as the audio system or passenger conversations 

• The module then uses this information to generate a sound wave that has the same amplitude as the engine noise but reverses it 

• The reversed sound wave is directed through the audio system speakers and combines with the original engine sound wave to cancel each other out 

 

Key Benefit 

• Reduced interior engine noise resulting in a quiet cabin

He asked if the speaker wires had anything to do with ANC, the speaker wires have nothing to do with ANC, do the speakers affect your ANC?  I would assume based on ohms, freq response and watts, yes.  Other than that NO.

 

I asked this before but nobody answered.  ANC in a perfect world may work wonders, but what about when your perfect world has the windows rolled down, how does ANC know the difference between an inside sound and outside?  There are no mics on the outside of the vehicle.  I prefer "Clean" sounding music rather then a signal that is getting injected with sounds to remove perceived unwanted noise.  I used to get strange cutouts where the sound was totally lost and then static sound from my passenger speaker, since removing ANC it hasn't happened.

Also have you ever had two sound sources playing through the same set of speakers?  You do with ANC, give it a shot on your computer and see how it sounds?  Music is sound, ANC is injecting sound no matter what, it is a frequency being generated and added to your music playing.

Here are the Sony Audio wiring diagrams from the 2014 Service Information DVD. They are definitely for the 2014 Fusion/MKZ Hybrids. There are also diagrams (4) for "THX Audio". Let me know if you need those too.

Hello, can you post again these schematics? they are not opening...
