Official summary
Due to a supplier chip-shortage, 2023 Bronco vehicles built on or before 11-Jul-2023 and equipped with a 6-speaker sound system come with a non-operational rear amplifier. This non-operational amplifier (service part number N2DZ-18C804-B) will not produce sound (by design) from the rear subwoofer. The non-operational rear amplifier and subwoofer assembly will appear identical to a working system. Customers have been notified and compensated appropriately for this change to the vehicle. For more details, refer to the Electronic Field Communication titled Product Offering Changes: Ford Bronco Au

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
