Alpine S-Series Plug & Play Full System Bundle Upgrade 2 & 4-Door (B&O System) | '21- Current Ford Bronco

Free US Standard Shipping with 30-Day Returns Ford Bronco B&O audio amp wiring differs by model year: Pre-2025 requires our T-harness connected at the factory radio for front-to-back speaker wiring; 2025+ uses integrated rear OEM harness only. Older models (pre-2025): The B&O amplifier requires running a new speaker wire T-harness from the amp (rear) to the head unit (front), connected at the factory radio, bypassing the OEM setup. 2025 and newer models: The updated B&O OEM amplifier integrates fully with the existing rear wiring harness—no need to run new wires to the head unit. The original harness is retained entirely in the rear. Demonstration: LINK We are pleased to announce our complete Play and Play full-system Alpine S-Series audio bundle for your Ford Bronco! This system is only applicable to the Bronco B&O systems. **2-Door Broncos: Please review the "Vehicle Fitment Guide" section below. We've taken the guesswork out of it for you so you can easily install a full system upgrade into your Bronco and enjoy the tunes rather than deal with trying to figure out what fits where and what is needed. Our bundles are 100" plug and play with all of the chosen components wired and terminated for smooth and seamless installation. Note: The integrated PAC module diverts the chime and alert signal from the dash center speaker to the driver side speakers. With this, the center channel speaker is abandoned, hence why the bundle does not include a dash center speaker replacement. Check out the Bronco Audio page to view other options.
