Custom Subwoofer Enclosures

SMS Car Audio builds custom subwoofer enclosures for customers who want stronger bass, cleaner fitment, and a more professional install than a generic prefab box. Enclosures can be planned for daily drivers, trucks, Jeeps, custom builds, and high-output systems.

Built-to-Order Bass Solutions

The enclosure is one of the most important parts of a subwoofer system. Airspace, port design, subwoofer model, power handling, vehicle space, and listening goals all affect performance. A properly planned box can improve output, response, and reliability.

Enclosure Options

• Single subwoofer enclosures
• Dual subwoofer enclosures
• Truck underseat boxes
• Jeep and SUV enclosures
• Custom fitment planning
• Built-to-order designs

Before Ordering a Custom Box

Confirm your vehicle, subwoofer model, available space, amplifier power, desired sound, and finish preferences before ordering. SMS Car Audio can help plan the enclosure around the system instead of forcing the system around a generic box.
