Proline-X Bronco Edition | Dual 12” Down Firing Sealed Subwoofer Box

This Proline-X Bronco Edition enclosure is specifically engineered for 6th generation Ford Broncos (2021-2025). The Direct Fit design ensures seamless integration in both 2-door and 4-door configurations. The enclosure utilizes factory mounting points and maintains cargo area functionality while delivering optimal acoustic performance. Professional measurements confirm compatibility with all Bronco trim levels and door configurations.

The downfire configuration leverages acoustic coupling with your Bronco's floor surface to enhance low-frequency response and create deeper, more impactful bass. This design approach provides superior acoustic performance while protecting the subwoofers from damage during cargo loading. The sealed enclosure delivers tight, controlled bass that complements rock, country, and electronic music genres perfectly.

This enclosure accommodates dual 12" subwoofers with maximum mounting depths of 8" and 11.25" cutout requirements. Premium brands like JL Audio, Rockford Fosgate, Alpine, and Kicker offer excellent compatibility. The 2.05 cubic foot internal volume is optimized for sealed subwoofer applications, ensuring proper acoustic loading for most quality 12" drivers.

The enclosure includes comprehensive mounting hardware and pre-wired terminals for straightforward installation. Basic automotive knowledge and standard tools are sufficient for most installations. However, amplifier wiring and integration with factory audio systems may require professional expertise, particularly for B&O equipped Broncos which utilize complex DSP systems.

Power requirements depend on your selected subwoofers and desired output levels. Most quality 12" subwoofers perform optimally with 300-800 watts RMS per driver in sealed applications. The enclosure's robust construction can handle high-power applications, but proper thermal management and amplifier matching are essential for optimal performance and longevity.

Sealed enclosures provide tighter, more controlled bass response with excellent transient accuracy, making them ideal for diverse music genres and smaller vehicle cabins. The sealed design offers superior durability for off-road applications and eliminates port noise concerns. This configuration delivers consistent performance across all frequency ranges while maintaining compact dimensions.

The enclosure requires minimal maintenance due to its sealed design and quality construction. Periodic inspection of mounting hardware and terminal connections ensures continued performance. The plush carpet finish can be cleaned with standard automotive interior cleaners. The downfire orientation naturally protects components from debris accumulation.
