MTX Audio F150C04BK12A-TN ThunderForm Amplified 12" Subwoofer Enclosure – 2004-2008 Ford F-150

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 F150C04BK12A-TN is a vehicle-specific, all-in-one bass solution designed to bring deep, powerful low-end to your Ford F-150 without sacrificing its interior utility. This custom-fit enclosure is rotationally molded from high-density polyethylene (HDPE), creating a virtually indestructible, non-resonant housing that fits perfectly under the driver’s side rear seat. Unlike most truck enclosures that use 10" drivers, this ThunderForm is loaded with a high-output 12-inch Terminator series subwoofer, providing significantly more surface area for deeper bass extension. This "Amplified" model includes a built-in 200-Watt RMS Class D amplifier specifically tuned to the enclosure’s volume, ensuring maximum performance and a simple, factory-integrated installation.

Key Features
  • Vehicle Specific Fit: Custom-molded specifically for the 2004-2008 Ford F-150 SuperCrew and SuperCab 4-door models
  • High-Output 12" Subwoofer: Features a larger 12-inch Terminator series driver for increased air movement and deeper bass compared to standard 10" truck boxes
  • Integrated Amplification: Built-in high-efficiency Class D monoblock amplifier delivering 200 Watts RMS (400 Watts Peak) of clean, dedicated power
  • Stealth Design: Mounts out of sight under the rear seat, preserving all passenger legroom and seat functionality
  • Indestructible HDPE Construction: Rotationally molded high-density polyethylene is resonance-free and color-matched in Black to resist scratches and match your interior
  • Smart Engage Technology: Automatically turns the system on when it detects a signal from the factory speaker wires (no remote turn-on wire required)
  • Universal Connectivity: Equipped with both high-level (speaker) and low-level (RCA) inputs for easy integration with any radio
  • External Bass Control: Includes an EBC remote knob, allowing you to adjust the subwoofer volume directly from the driver’s seat
  • Sealed Enclosure Precision: Features a 0.94 cubic foot sealed internal volume for tight, accurate, and musical bass response
  • Frequency Response: 24Hz – 160Hz
  • Dimensions: 8.25" H x 34.5" W x 14.5" D

Runs big
Size: 24, Color: Night Hawk
Super cute but runs big. I’m typically a 25 and bought a 24. It’s still too big

SUPER great denim-should last for years!
Size: 30, Color: Truest Blue
lI don't know if these will be flattering on me, but I LOVE THEM. They're hip and cool and I will wear them although I am 65. Would look best with shorter shirts, but of course, not showing belly. A slim young woman would "kill" this look. Denim is heavy duty and all hardware top class. The ad said to size down, but I ordered my regular size. The waist is a little tight on me, but the barrel legs are loose and hang nicely. Definitely something I will wear with platform ankle boots or sneakers. I anticipate people will absolutely love them (younger folk) where people my age, may say hmmm because they are a statement piece.

Love these authentic FP moxie jeans
Size: 29, Color: Truest Blue
I purchased two pairs of moxie FP jeans on Amazon both on sale. I love how different they are. The paint splatters are just the right amount in my opinion. I think the barrel leg is just wide enough without being obnoxious. I like an oversized look and these were the right price for me on Amazon. I love the rope waistband on these too
