Watch a full tutorial as a 2025 Ford Bronco Truck will have a Stinger 700 watt bass amplifier and an Audio Control 12" shallow mount subwoofer installed. We will be adding this amplifier while keeping the factory audio sound system.
Note - this Bronco was NOT equipped with the Bang & Olufsen (B&O) audio system from Ford. If you have B&O, the factory amplifier and subwoofer is located behind the rear panel where you need to tap into for signal to your new LOC / Amp.
This video applies to Ford Bronco models for years 2021, 2022, 2023, 2024 and newer. This video also includes trim removal, amplifier wiring, and installation.
*Factory Subwoofer wiring located behind the rear cargo panel next to the factory subwoofer.

If you want a pre-assembled LOC T harness (for the base trim non-B&O Broncos), I offer one on my website here:

If you are instead installing a 4/5 or multi channel amplifier to also power your door / dash speakers (for the base trim non-B&O Broncos), I offer a full harness here: provobeast.com/product-page/2021-ford-amplifier-t-harness-wire-kit-for-factory-oem-head-unit
