MTX Audio F250X00BK20A-TN ThunderForm Dual 10" Amplified Enclosure – 1999-2016 Ford F-250/F-350 Regular Cab

FITMENT NOTE: Fits 1999-2016 Ford F-250 and F-350 Super Duty Regular Cab (Standard Cab) models. Does NOT fit SuperCab (Extended), Crew Cab, or 2017-Up New Generation Aluminum Body trucks.

The MTX F250X00BK20A-TN is a custom-engineered, all-in-one bass solution designed to bring massive low-end to the limited cabin space of Ford Super Duty Regular Cab trucks. This high-output ThunderForm is rotationally molded from high-density polyethylene (HDPE), creating a virtually indestructible, resonance-free housing that fits perfectly behind the seat. This "Amplified" model is a complete plug-and-play system, featuring a built-in 200-watt RMS Class D amplifier perfectly matched to drive the dual 10-inch Terminator series subwoofers. Finished in a scratch-resistant Black, the F250X00BK20A-TN provides a stealthy, factory-integrated look while delivering the deep, impactful "Thunder" that MTX is legendary for.

Denim feels thin but soft
Size: 32W x 32L, Color: All My Days Selvedge
The denim seems thinner than from years ago. 100% cotton feels soft. Fit me same as other stretchy 505 that are made with elastine. Waist size is fine. Haven't washed them yet. Yes, the price is high, but I like the 100% cotton and will likely buy more selvedge jeans.

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
