Free US Standard Shipping with 30-Day Returns We are excited to introduce our Plug-and-Play Hertz-Audison Full-System Audio Bundle, designed specifically to transform the audio experience in your Ford Bronco. This premium system is exclusively compatible with Broncos equipped with the factory B&O audio system, delivering high-performance sound, superior clarity, and powerful bass—all while maintaining a seamless, factory-integrated look. Whether you're cruising the highway or hitting off-road trails, this upgrade ensures exceptional audio quality to match the rugged capability of your Bronco. TIP: Choose no subwoofer and opt for this DUAL 10" TAILGATE ENCLOSURE! 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 2-Door Broncos: Please review the "Vehicle Fitment Guide" section below. For the Non-B&O, see the product page: LINK Note: The integrated PAC module diverts the chime and alert signal from the dash center speaker to the driver-side speakers. Because of this, the center channel speaker is bypassed, which is why this bundle does not include a dash center speaker replacement.
