Transform your single cab truck into a mobile soundstage with a custom subwoofer enclosure. Whether you’re looking for deep, resonant bass or ear-splitting loudness, this guide will provide all the necessary steps to design and build a sub box that meets your specific needs.
The size and volume of the sub box play a crucial role in the performance of the subwoofers. Determine the optimal box volume based on the manufacturer’s specifications for your subwoofers. This will ensure they operate within their recommended parameters for maximum sound quality.
Port Design and Tuning Frequency
In a ported sub box, a port is used to enhance the bass response. Slot ports are commonly used in truck boxes, providing a deeper, crisper bass. The size and number of ports affect the tuning frequency of the box. A lower tuning frequency will produce a deeper bass response. Use a port tuning calculator to determine the appropriate port size and length based on the box volume and desired tuning frequency.
Designing the Loudest Subwoofer Enclosure
Enclosure Type and Volume
For maximum loudness, a sealed enclosure is recommended. Unlike ported enclosures, sealed enclosures provide enhanced bass accuracy and control. Calculate the enclosure volume based on the subwoofer’s specifications to ensure optimal performance.
Materials and Construction
Use high-quality MDF (Medium Density Fiberboard) or plywood for the enclosure. These materials offer strength, sound absorption, and durability. Reinforce the enclosure with internal bracing to minimize vibrations and improve sound quality.
Choose a subwoofer that fits within the enclosure’s specifications and can handle the desired power output. Consider the subwoofer’s frequency response to ensure it covers the desired bass frequencies.
Amplifier Pairing
Match the amplifier’s power output to the subwoofer’s requirements. Class D amplifiers are recommended for their efficiency and compact size. Use proper gauge wire to connect the amplifier to the subwoofer.
Designing and building a custom sub box for your single cab truck requires careful planning and attention to detail. By following the steps outlined in this guide, you can create a sub box that optimizes sound quality, maximizes loudness, and complements the unique acoustic environment of your truck.
FAQs about Regular Cab/Single Cab Truck Sub Box Plans
What are the key considerations for designing a custom single cab ported truck box?

What is the recommended port tuning frequency for a deep bass response?
Around 30-35 Hz.
What are the optimal materials to use for constructing a sub box?
High-quality MDF or plywood for durability and acoustic performance.
How should the subwoofers be positioned within the box?
Facing the front of the cab for optimal sound dispersion.
What is the recommended thickness for the wood used in the box’s construction?
1 inch for sufficient rigidity and bass response.
What type of enclosure is recommended for maximum sound output in a single cab truck with the middle seat removed?
Sealed enclosure for enhanced bass accuracy and control.
How should the enclosure be secured within the truck?
Mounted securely to the truck’s frame or floor to prevent movement.
