De-complicating Audio in the Bronco

[mObridge]

Budget friendly diy

I like the Hertz CX100s across the dash and then the MP165 in the kicks.
The morels tempo ultras sound better but dont fit in the dash that well.

The Audiofrog range is also another great option and they do fit!

Just did a 25 Heritage with base audio two weeks ago and found its the new a2b for the sub only amp. Acm still powering all the other speakers. Have a dtc for a2b. Haven’t found anything with forscan to disable the a2b to get rid of it.

Did you remove the factory sub amp?

Is there a subwoofer that would still fit in factory space and work with this?

Kicker compr 8 inch!

I’m running Audiofrog tweeters and midrange in the dash and they are sounding awesome

I can’t find it but thought someone posted ford changed the 25 b&o configuration? If so are there systems for beginners that will work better than others?

Which ones are you running in the dash? Any modification needed?

Im running the GB40 in the dash, they are a direct fit without a need for a speaker adapter

Hi all. So I installed the MObridge amp today. Or at least I think I did. When I finally turned on my car, hoping for the big reveal, I’m getting no sound and my radio’s volume won’t go above zero. I’ve checked all the connections (I think). I have not configured the DSP yet. Maybe that is the issue? If anyone has any ideas, please let me know. I’ll plan to call Fraser on Monday if I can’t figure it out.

Had the same problem when I put it all back together. There was one 4 pin wire coming out of the mobridge harness that I hadnt plugged in because I assumed that all of the separate wires coming out of the harness would plug into the various loose wires coming in elsewhere, not back into the amp (why would you plug the amp into itself? I figured they would just wire that up internally).

Turns out that one plugs into the Mobridge amp on the OTHER side. After I plugged it in on the other side, volume worked and everything worked perfectly.

Elbroncodor, thank you. I didn’t have that plugged in. I just plugged it in and now the volume control will show the volume increasing but I can’t actually get any sound.

Send a pic of install. Check to see if you have connector in right slot of head unit. It could be programming on the amp. Mine was missing and had the same problem. Fraser can tell you and get it remotely setup.

 

[ChrisNYC]

Thank you all. Here are some pics of the amp. For the harness, I have it in the far right side replacing the black connector.

That 4 pin connector that plugs into our amp is CAN from the factory connector. Not possible to wire internally

**2025 Bronco updated B&O**

Ok so we have been able to dissect this system and ill outline the differences between it and the old system.

There is indeed a new amplifier, now all new Fords received an amplifier update in the 25 model year. This updated changed the A2B (audio bus) communications from the headunit to the amplifier. However, for example in the F150 B&O system ford basically kept the amp the same and just changed the coms. There was no improvement to the actual audio quality itself (Good for us, not good for people who paid good money for a 'premium' Audio system).

2025 Bronco owners did get lucky! No that lucky though... The amplifier used in the Bronco has now changed to the same one as previously seen in the Unleased systems in the F150. This amp has more channels and slightly more power so the system itself is no doubt better than the 24 Bronco system. Still lack luster to most though but non the less an improvement!

As of right now the only way to properly upgrade these audio systems is to use the F25 Pre-amp from NAV-TV (https://navtv.com/products/NTV-KIT1...tkJGzxsJGTXWL98c1Byc3FQpLeQ68NJGeb5taGams30mY)

I have attached the new wiring diagrams.

Does this mean that the rear pods are now amplified? Is there any idea as to the power / channel?

They were always amplified however it was by the front ACM @20w RMS ish. Now they are driven off the back, they now would probably be running between 30-40w RMS at absolute best. We are yet to measure this though.
