American Sound Connection GM2X10-EX07 Dual 10in Sub Box - Custom Fit

Our review of the American Sound Connection GM2X10-EX07 finds it best suited for Silverado and Sierra owners who want a clean, powerful bass upgrade without cutting carpet or losing cargo space. The single biggest reason to consider this enclosure is its custom fit for 2007-2013 Chevy Silverado and GMC Sierra extended cab trucks, which delivers strong low-end performance while tucking under or behind the rear seat for a near-factory look. It balances sound quality and practicality, though build durability has mixed feedback from some users.

Key Features

• Excellent construction: The enclosure is built from quality materials and assembled to hold dual 10in subwoofers securely for long-term use.
• Optimized sound quality: The internal design and 0.60 cubic feet of air space per sub aim to produce cleaner, deeper bass that complements full-range speakers.
• Custom fit: Shaped for the rear seat area of 2007-2013 Silverado and Sierra extended cab trucks to preserve a factory appearance and maximize usable space.
• Compatibility: A 6in mounting depth accommodates the majority of 10in subwoofers so installers have wide driver options.
• Low profile: With a depth of 14-3/4in and front/rear heights that taper, it fits under seats and near transmission humps without excessive intrusion.

Who It's For

This enclosure is ideal for truck owners who want to add substantial bass to their factory or aftermarket audio system while keeping a neat, installed appearance. Installers and DIYers who prefer a vehicle-specific solution will appreciate the fitment and the ability to use common 10in subs with the 6in mounting depth.

Those who need a sealed box tuned for very compact subs or who require heavy-duty carpet and reinforcement for extreme SPL competition may want to look elsewhere; some customers reported carpet rips and occasional panel damage under heavy use.
