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
