Need help with adding amplifier to my 2022 F250 B&O
In my 2025 Mach E with the B&O system I am using the APH-FD02 harness wired into my Audiocontrol D-5.1300. Within the harness their is a set of brown wires and a set of blue wires that I believe are for the dash speakers, would that be correct? If so, couldn't I un those in parallel with the front speakers and get adapters so I wouldn't have to run speaker wire to the back for the upgraded dash speakers (tweeters/mid)?
You didn't mention it, but if your Mach E still has the factory amplifier, I'd strongly recommend removing it from the equation. You don't want to try keeping the factory amp, amplifying its signal, and then running it through the D5.1300's DSP. What happens in that scenario is you're double-stacking DSP tuning — the factory processing on top of the D5.1300's — and amplifying an already heavily compressed signal. It'll get louder, sure, but your sound quality will never be where it should be with that kind of setup.

Yes — just make sure to grab a wiring diagram for your exact vehicle from https://www.motorcraftservice.com/ to confirm everything.

I'm thinking I still have the amp involved in this situation. With the FD-02 I believe I am just intercepting the speaker signal after the digital signal is processed since I can't convert the digital signal using this harness, correct? What if I ran it through a LC5i Pro or KEYLOC (or simiar)
Here's the core issue: even if you manage to counter-balance everything B&O has done to the signal, you're still stuck with low-resolution outputs from the factory's DAC (Digital to Analog Converter).
Think of it this way — you start with beautiful, high-resolution lossless audio streaming from your phone. Picture it as a 4K image. That quality holds all the way to the factory amplifier. But then the factory system downsamples and converts it to something closer to Super Nintendo graphics from 1990. From that point on, no matter what you do, you can't bring it back to 4K. You're just polishing Super Nintendo graphics.

What you really need is an amplifier replacement interface, like the ZEN A2B, to get a clean, usable signal to work with. The LC5i is just a converter — it changes the signal path but doesn't actually correct anything. And while the KeyLOC is a great piece of equipment, it doesn't handle the high frequencies well in these vehicles because the B&O system is just too heavily manipulated. Even a Mosconi DSP can't truly make it sound good at that point.

Crossovers are on the tweeter itself, and depending on the factory system in the truck will determine what is running the tweeters and how it's wired. A lot of variations in these trucks

On the 2018 the tweeters are powered from the head unit. Hope that helps.
