Premium Alpine Subwoofer + Custom Ford F-Series Enclosure: The Ultimate Bass Solution
The Alpine RSW10D4 subwoofer combined with our Proline X direct-fit enclosure creates the perfect bass solution for Ford F-150 (2015-2023) and F-250 (2017-2023) truck owners who want serious audio performance without sacrificing valuable space. This carefully engineered system addresses the unique acoustic challenges of Ford SuperCrew and Super Cab trucks by positioning a premium shallow-mount subwoofer behind the passenger-side rear seat, maintaining your under-seat storage while delivering impressive low-frequency response.
Performance That Exceeds Expectations
The Alpine RSW10D4 shallow subwoofer is the heart of this system. It features an oversized 4-inch voice coil powered by a neodymium magnet that delivers an impressive 600W RMS of power handling. Despite its compact design, requiring only 3.25 inches of mounting depth, this subwoofer achieves the same cone movement (20mm of excursion) as full-size subwoofers, producing deep, accurate bass that enhances every genre of music.
Custom-Engineered For Your Ford F-Series
Our Proline X enclosure isn't just another generic box – it's specifically designed for the acoustics of Ford F-Series trucks, with an optimal 0.5 cubic feet of internal volume for enhanced bass frequencies.

Ultra-Shallow Design
The Alpine RSW10D4 features an innovative shallow-mount design that's perfect for the space constraints of modern trucks. Despite its compact profile requiring only 3.25 inches of mounting depth, this subwoofer delivers premium bass performance that rivals much larger drivers. This makes it ideal for Ford F-Series trucks, where installation space is limited but audio expectations remain high.
Extreme Output Capability
Don't be fooled by the slim profile – the RSW10D4 features the same cone movement (20mm of excursion) as full-size Alpine R2-Series subwoofers. This remarkable excursion capability allows the shallow driver to move significant air volume, producing deep, powerful bass that enhances any music genre from hip-hop to country, rock to classical.
Advanced Motor Structure
At the heart of the subwoofer is an oversized 4-inch voice coil controlled by a powerful neodymium magnet. Alpine's proprietary Gen2 DD-Linear Magnetic Circuit technology employs a compact and efficient dual-gap voice coil structure that provides superior control over the motor, resulting in significantly lower distortion and precise bass articulation even at high volume levels.
Optimized Sound Projection
The lightweight yet rigid aluminum dust cap allows for quick sound transitions with minimal distortion. This specialized design efficiently projects bass off the speaker's surface, creating a hard-hitting yet smooth low-frequency response that integrates naturally with your vehicle's existing sound system.
Superior Construction Quality
The RSW10D4 is built with a die-cast aluminum frame providing the rigid, sturdy foundation for powerful bass reproduction. This premium construction ensures high energy transfer while minimizing unwanted resonance and distortion, resulting in cleaner, more accurate bass performance throughout the subwoofer's operating range.
Flexible Installation Options
With dual 4-ohm voice coils, the RSW10D4 offers flexible wiring configurations to match a variety of amplifiers. This versatility allows you to wire the subwoofer for either 2-ohm or 8-ohm impedance, making it compatible with a wide range of aftermarket audio systems and amplifier specifications.
Ford F-Series Direct-Fit Design
The Proline X enclosure is specifically engineered to fit 2015-2023 Ford F-150 and 2017-2023 F-250 trucks with SuperCrew or Super Cab configurations. This isn't a generic "universal" box—it's a precision-designed solution with exact dimensions that fit perfectly behind the passenger-side rear seat without modification to your vehicle.
Space-Efficient Solution
Understanding that truck owners value their cargo space, we've designed this enclosure to maximize audio performance without sacrificing utility. The enclosure tucks neatly behind the rear seat, maintaining full access to your under-seat storage area – a major advantage over universal solutions that often require compromise.
Acoustically Optimized Volume
With 0.5 cubic feet of internal volume, this enclosure provides the ideal acoustic environment for the Alpine RSW10D4 subwoofer. This precise volume has been calculated and tested specifically for this driver to deliver optimal bass response and transient accuracy in the unique acoustic space of Ford F-Series cabs.
Premium Construction Quality
