FITMENT NOTE: Fits 2004-2008 Ford F-150 SuperCrew (Crew Cab) and SuperCab (Extended Cab) 4-Door models. Does NOT fit 2004 "Heritage" (old 2003 body style), Standard Cab, or 2009-Up F-150 trucks.

The MTX F150C04C12-TN is a custom-engineered, vehicle-specific subwoofer solution designed for 2004–2008 Ford F-150 owners who want high-output bass with a factory-integrated look. Finished in Charcoal to match common gray interior trims, this ThunderForm enclosure is rotationally molded from high-density polyethylene (HDPE), making it virtually indestructible and resonance-free. While most under-seat enclosures are limited to 10-inch drivers, this model is specifically designed to house a larger 12-inch Terminator series subwoofer, providing the extra surface area needed for deeper, more impactful bass. As a "Loaded" model, it is non-amplified, giving you the freedom to connect it to your choice of external mono or bridged amplification for a truly custom-tuned audio experience.
