Watch a full tutorial as a 2021 Ford F150 Truck will have a Stinger 1000 watt bass amplifier and Skar audio 12" shallow mount subwoofers installed. We will be adding this amplifier while keeping the factory audio sound system.
Note - this F150 was NOT equipped with the Bang & Olufsen (B&O) audio system from Ford. If you have B&O, the factory amplifier and subwoofer is behind the back seat where you need to tap into for signal to your new LOC / Amp.
This video applies to Ford F-150 models for years 2021, 2022, 2023, 2024 and newer. This video also includes trim removal, amplifier wiring, and installation.
