FORscan question about upgrading B&O system

[Nibroc99]

Hey y'all, 2022 Bronco Wildtrak 4-door with the B&O system and Lux package.
First of all, I don't want to hear about any other amplifiers or A2B interfaces haha - I've already got this stuff and will be using it. I am aware of the mObridge system for rich people (this is a joke about how expensive that system is, not a dig at people who have it ), and I know Kicker has their own thing that plugs right in, etc. No need to point out how good those systems are or that I should use them instead.

With that out of the way, a rundown of my setup. I already have this equipment from my setup in my old vehicle, which I kept when it got totaled by a drunk driver (big sad). I tapped into the factory stereo using a LOC, which obviously you can't do with the A2B B&O system. I would have opted for the 6 speaker system if I could, but I needed a used vehicle fast when my old one got totaled and couldn't be so picky, haha.
I'm gonna be upgrading my sound system using equipment I kept from my old car that got totaled. I will have a full-range component setup in both the front and the rear (specifically two sets of the Skar SPX-65C) driven by a 4-channel amp (SKv2-100.4AB). I've also got a Rockford Fosgate R2-500X1, which will drive a Kicker Comp-R 10" woofer in its own box. I'll likely just remove the existing subwoofer enclosure behind the panel to make a good spot for my two amps, especially since the Skar amp is a big boy. I'm going to interface into the existing stereo using the PAC AmpPro AP4-FD31 Amplifier Interface, which I finally just saved up enough to purchase. For the rear speakers, I'm gonna put the 6.5" component speakers in SSV pods, which I'll load with sound deadening. I'll put the rear component tweeters likely in the overhead bar in front of the pods (but I'm going to experiment with a few locations before deciding where to drill holes lol).

Now for my FORscan question. I've heard people talk about making changes in FORscan for the audio, but I've done so many searches in Google, Facebook groups, and on both this and the Bronco Nation forums, and I can't for the life of me find specific info about what people are changing - only "I made the changes in FORscan" and stuff like that. Is there anything I'll even need to do in FORscan with the PAC AmpPro AP4-FD31 or does anyone know if that just outputs full-range flat EQ signals to the front and rear channels without any FORscan changes needed?

Thanks in advance for any help everyone!

There are no Forscan changes for the B&O system that have been discovered, to my knowledge

You absolutely could use a LOC with B&O, but the wiring may be a bit different, and, as you go to great pains to point out - you have zero control of the input signal and you get what you get that way

Unfortunately, none of the speakers have full range outputs, so I'd need to use a DSP to combine the signals of at least two outputs anyway if I were using an LOC, at least based on what I've read. This is just because I'm using my own crossovers, which I'm sure have a different freq split than the factory front channels. I haven't measured any output signals with my oscilloscope yet though so that's hearsay lol.

This is all true and why no one really recommends it. Even with a DSP you may have some issues because none of the signals are clean - you are still getting a post-processed signal with EQ and timing adjustments, and trying to use more processing to counteract that.

Which is why the A2B interface is recommended

Gotcha gotcha. Well, hopefully the PAC AP4-FD31 outputs a clean signal and not a processed garbage signal haha. I'll report back once I hook it up and check the RCA outputs with my oscope

Let us know how it turns out!

Definitely going to do a nice write-up of my build!

Question - do you know if there's a certain wire I can tap into for the signal wire so that when the radio is on the amps will turn on with it? Rather than just making it run on ignition power which I could easily do of course.

On the B&O I’m not sure. Most folks use line signal detection on the speaker level input for a trigger. There are separate modules you can get if your LOC doesn’t have it built in

Gotcha, I'll just have to do that then if I can't find a wire to tap. If I do find something I'll certainly post it here and on my build log thread I just started. Thanks!
