Is this Wiring Diagram Correct for the 9-Speaker non B&O?

[RedRocket]

I found this but cant get clarification.

Are the door mids wired in parallel with the A Pillar tweeters, as indicated here?

This is what PTS shows for the 9-speaker left-hand drive config. I assume that some of these are 2-way speakers where Ford counts them as two speakers instead of one, because it only shows a total of 6 speakers wired to the DSP.

Interesting. On the 9 speaker, in my car, i have 9 distinct drivers.

1 - Center Dash (IP)
2 - L and R A Pillar Tweeters
2 - L and R Upper Door 3.5” Midranges
2 - L and R Lower Door 6.5” Woofers
2 - L and R Rear Quarter Pannel 6.5” Full Range (non 2-way)

From what I understand the B&O has 2-Way speakers (Woofer with separate tweeter) in the rear, plus a Subwoofer, making 12 speakers.

I just bought the Maestro A2B amplifier replacement inteface + AR-FO5 for 18 UP Ford Vehicles. It’s wiring guide confuses the issue for me.

I think I found it. The other 3 speakers in the 9 speaker system are powered by the ACM.

Ah, now that makes some sense. That means the tweeters and center will have to have new wiring run from the amplifier I am installing in the trunk. The ACM, that is built into the head unit of the car, correct? it does not run to the amplifier in the rear of the vehicle?

Thank you so much for all of this information. Very helpful.
i am going to bypass the ACM for those speakers and run new cable. I have an 8 channel amp with full DSP so I can just “roll my own”.

Ford really makes all of this a bear.

So you mean the 9 speaker system is really a 5 speaker system.



Counting individual speaker Drivers In a system is lame. Every OEM does it I’m sure.

With that logic and math, that means that my home theater has AT LEAST 34 speakers

It’s a 5 channel system if you count the front stage as a proper 3 way speaker setup. But it appears they have it segmented into a 7 channel system, breaking the front components up. It’s kind of idiotic how they did it.

so ford math, 9 drivers is a 7 channel system that should be a 5 channel system. Adding a sub should be 5.1

the B&O should be a 5.1 system since it has a sub, but they say it’s a 12 speaker system.

Is it easy to add a sub to a 301A with the “9” speaker system? Honestly didn’t realize it didn’t have a sub smh

It’s not too bad. The convertible is a bigger pain. But the trick is to tap the rear speakers and use an amp with line level input, or a LOC. Then it’s about routing power and a remote turn on to the engine bay. A ground of course.

im doing a stealth install and using a Cerwin Vega Slim Powered sub that fits in the spare tire. https://cerwinvega.com/products/12-...ered-subwoofer-vpstx12?variant=43108266508468

now… after using the factory system for a month, I’m so dissatisfied I’m doing a full system replacement, so ill still use that sub, but use a DSP to control it instead of a LOC or line level.
