DIY Subwoofer and Amplifier Upgrade
You have been busy, looks good.

I finally had some time to write up this mod. It is definitely worth the effort for anyone who got caught up in the
Option Code 58E, 2023 Subwoofer delete.
This option code will
automatically be added to affected vehicles. Vehicles with this option will be produced with 6-speakers; however, they will be equipped with a non-functional amplifier that does not support subwoofer functionality. The vehicle will not retrofit (meaning Ford will not upgrade this in the future).
" This particular option deletes the subwoofer from models equipped with the standard sound system, which typically has seven speakers including the subwoofer. This option pertains to Base, Big Bend, Black Diamond, Outer Banks, Badlands, Wildtrak, Everglades, Raptor, and Heritage Edition series models. However, it seems as if this will apply to all non-B&O sound systems moving forward. "
The ‘Audio – Six (6) Speakers Subwoofer Delete” option will be listed in the Optional Equipment section of the Window Sticker and customers will receive a
$250 MSRP credit on the vehicle invoice.

First, a big shout out to
@FCoyote at Bronco6G for his informational links.
Second, these are the parts (or similar) you will need:
Background, why does the amp and speaker need to be replaced? Short answer: Ford inventory constraints. Dummy amp has no chips on circuit board. Dummy speaker has no magnet. It appears the dummy components are there only to connect the viable wiring.
