Factory Premium Audio B&O amp Wiring Harness

[mshoenfelt]

I have a 2019 Lariat crew cab and getting ready to pull the interior to install sound mat for sound control and heat/cold insulation. My Lariat had the standard 6 speaker audio system. I don't need an expensive sound system but did want the Premium system. My thoughts are to purchase a factory B&O amp from a salvage truck, factory sub woofer (I know they are not the best but I just want better sound and not louder), and going to replace the factory speakers with some Polk setups and add the center speaker.

My question is, Is it likely that all the Lariats had the wiring for the premium audio even if it was not installed?

I've tried to look, but can't tell without pulling it apart, for which I would like to only do once when installing the sound mat. I don't want to buy the harness if it's already there and just no utilized. To my knowledge, I think there is just one harness from front to back of the cab that connects the B&O amp to the system and the bass has it's own harness that connects to the amp. Also seems that the center speaker connection might be present also and just need the speaker and speaker cover instead of blank cover.

Any insight would be helpful.

I have not dug into this deeply yet, as I plan on down the road audio upgrade myself, but mine already has B&O with Sub.
This subject surprisingly is not detailed (covered) in this forum other than aftermarket mods, I searched through some of the posts it is mentioned but no detail on step-by-step upgrade.
Basically, you have (XLT-6 speaker system) so the speakers are powered from the ACM

Lariat (8-Speaker) - Has harness going from ACM to AMP and Speakers are powered from AMP.
Amp to speaker/sub harness - contains the wiring needed to power the Speakers, note the B&O has different rear door speakers (Coax) This is where Ford gets the extra 2 speakers) each rear door speaker counts as 2. So, a total of 10 speakers, which is actually 8 on paper)
Marketing Tactic- To deceive

This harness (Amp to Speakers) adds the wiring for the Sub and Center Dash Speaker, in addition to the Door Speakers

So, by just using some of the posts as a ref and the wiring diagrams, I don't think you have the harness needed for just plug and play But as I stated I have not touched my audio as of yet, so I don't have any specific knowledge.

Hopefully, someone has done it and can shed some insight, on specifics if you plan on keeping factory in lieu of aftermarket (Sub)
I suggest using the search and see if you can find any info on your upgrade, I have used other forums and there were detailed postings on what is needed, but this being a truck and is limited (space-wise) it is not a highly popular audio mod that I can see on this Ranger 5G

Note: Crutchfield has some details on Ranger Audio System, but does not state if all rangers have the sub wiring - This is an indicator that it is only on the (8 speaker) system

BTW, my first aviation job was in Greensboro, loved the area and welcome to the forum

My lariat does NOT have the B&O Premium system but rather the standard set up.
What I do know is that the front doors have separate tweeters from the midrange speakers, the rear doors have full speakers, and I have no center speaker, just a solid cover.

In many vehicles, when you get the top trim, they usually use the same wire harnesses but just don't have the Premium items installed/plugged in.

I'm just looking to see if anyone else had a Lariat with the standard audio and then upgraded and noticed if the factory premium harness was already present or if I need to purchase one.

The Premium B&O sound system just seems to add the B&O amplifier behind the rear seat back drivers side and Bass amp in the center next to the amp. It also changes the solid center cover for a dash speaker cover with a center speaker added.

As for wiring, The diagram online only shows a long harnes going from the B&O amp in the back to the receiver up front. The Bass has its own short cable that runs from the Bass to the amp. In what I am seeing, there are no wires going from the amp to the speakers, just the one harnes going from amp to receiver.

I tried to look and see if the Amp harnes was present but could not without doing disassembly outside in the cold. It could be there and just be tucked out of the way which is what I was hoping someone could tell me.

As for my planned upgrade, looking at
- pulling the door panels off, adding soundmat, then upgrading the front speakers with split Polk DB+ 6502 and the rears with Polk DB+ 652.
- Then going to change out the center speaker blank cover for an actual factory speaker cover and install a Kicker 47KSC3504 for the center channel.
- Drop the headliner and install some lightweight soundmat with insulation and run my dashcam wiring for rear camera and power.
- Pull the rear seats, storage, and back panel. Pull the front seats and then pull the carpet and install sound mat. At this point I will run the B&O amp harnes if there is not one. Then reinstall all along with the factory B&O amp and Factory Bass.

This should provide sound deadening, some insulating features to help keep heat and air in and reflect sun heat an outside cold out (A/C and heat will not need to work as hard). Though the B&O system is not the best, it "should" be quite the improvement especially with the Polk speakers.

I'm just hoping someone can tell me if the B&O amp harnes is present in all lariats even if you did not get the premium sound. That way I can either order it or save the money and not be in the middle of an install and need one.

I'll update this thread after I get done and maybe add some photos for whomever is interested in the same.

This is the wiring diagrams that I have, for speaker wire runs, there are more relating to the Microphone, Rear Cam etc., but those additions would require the Sync Module and related components. I believe
Note: 8 Speaker sys 2, is for Chimes (I Think)

From what I have seen so far Ford’s harnesses are specific to the package(s) ordered. They don’t have any extra wiring. So in your case everything would need to be added for a B&O system that doesn’t exist already.

Roger that, thanks! I was kind of figuring that. The harness is not too much so I guess I'm going to end up ordering it.

I've stripped my 2021 Lariat, 6 Speaker down on the inside quite a bit as am in the process of upgrading the audio. I've already put soundproofing in the all the doors and behind and underneath the back seat. I've pulled almost every trim panel from the inside at some point. I'm almost certain there is not a connection for the sub. There is also not one for the center speaker in the dash.

I'm thinking I can purchase the B&O harness that runs from front to back because I can see it as a parts availability. I have a B&O amp, still need to get a B&O bass.
I'm wondering if this will be enough to "upgrade" my standard 6 speaker to the Premium.

What I am still not clear on is the following:

1. parts list only shows 1 cable running from B&O amp in the rear to the front of the cab. I assume it just plugs into the receiver.
2. The parts diagram does NOT show separate wires coming from the amp to each speaker. I am assuming that is done via the already present wiring, be it the canbus or from the receiver.
3. I'm not sure where the wiring for the center speaker is supposed to come from. I have yet to find if it is a separate harness, a branch of the B&O amp harness, or something else entirely.
4. I'm assuming that the receiver is the same receiver regardless if it is premium or not. I have the large screen with Sirius XM so I'm hoping that is not different. I have to do more research into part numbers to see if they are the same.
5. I'm not worried about the Bass to amp as the bass "should" come with it's own cable that plugs into the B&O amp that is sits next to on the cab back wall.
6. As for speaker upgrades, I've found adapters from factory plugs to the aftermarket upgraded speakers for the rear door and bottom front door. I have to find adapters for the tweeters for the front door and will need an entirely different adapter for the center speaker as it is different than the plugs in the door and that is providing I can figure out the center speaker wire issues of where it is or how to get one.

This is kind of a fun project. I know many would just advise putting all aftermarket, but I really just want a setup that is factory except with better speakers (though I am aware of the less than glamorous performance of the factory bass but that is ok with me). I'm sure the Polk speakers will make a huge difference and being able to use the factory B&O amp and tweak with Forscan should be just enough to make me happy without breaking the bank.

Ok, for those that are sort of following...........

I did a bit of research today and came to the following assumptions:

1. It appears that all the Lariat crew cabs use the same dash harness, part #14401, regardless of options. The harness has a wire set running up to the center of the top of the dash and I am hoping that is the center speaker channel and it is just not run through on my truck. I pulled the dash speaker cover (solid cover for mine instead of perforated for speaker)and did not find any wires under the cover. They "could" be just not run through and tied to the dash harness. I would need to pull the radio to look behind but it appears to come off the top of the harness between the speedo gauge and the radio and then run up to the center speaker position. I found a video( 2019 RANGER DASHBOARD WIRING HARNESS REPLACE - YouTube ) where a mechanic replaced a dash harness due to a rodent chewing and you can see the wires running from the main harness to the speaker area as a part of the harness itself (no connections in between). Being the same part number for all, maybe I will get lucky? Or, maybe the wires are for something else like a sensor I am not seeing but I don't think so. Interesting video though!
2. It appears that the radio itself is the same, Part#18806, regardless of premium or not.
3. It appears all the cables in a non-premium are the same as a premium with only a few exceptions, that being single or dual USB ports up front and a different cable for that, and the 2 cables that connect together to run from the receiver to the B&O Amp.
4. It appears that I would need to purchase two cables, Part# 14D202A that is behind the dash and goes from Radio Receiver behind the dash to the passenger side, and another cable part# 14D202B that runs from the formerly mentioned 14D202A on the passenger side, along the passenger side front to back, then jump passenger to drivers side near the rear going over the tunnel and then runs under the storage and back to the back wall to connect to the B&O amp.
5. There is no cable noted anywhere for the Bass to B&O amp connection and I am assuming that the Bass comes with it's own cable as part of the bass and then it simply plugs into the amp itself.
6. Front door, Tweeters, and Rear door speakers have the same part number for the premium as the lesser system.
7. B&O uses a different dash speaker cover and the Tweeter covers and different (have the B&O medallion on it that I really don't care about).

It appears to me that the receiver sends signals back to the Amp via the above mentioned two connected harness parts and then from the Amp it splits off Bass signal to the Bass module and returns signal via the connected harness parts to the receiver.

It appears that the receiver acts as a controller and then routes the individual speaker signals out to the respective speakers. It appears that the speaker signals do not come from the amp itself but rather routed through the receiver. I know that there are some changes that need to be made with FORSCAN and I'm thinking that those software changes are what tell the receiver to either send signal to the amp and then pass it on or to send it direct to the speakers.

For any with interest, I'd like to hear your thoughts on this to see if my reasoning is sound based on what I have found. It appears that others had some interest but nobody has really dug into this to the extent I have.

(For those with a Lariat crew cab, your experience sould be similar, for those with an XLT, You would need to have parts similar to the Lariat and I'm not sure it would be worth or possible to change out all the harnesses and receiver and such).

Did you ever complete this upgrade?

Would be nice if the center speaker wire was there but just tucked away somewhere.
