Welcome to our blog article on blueprint Silverado extended cab sub box plans. In this article, we will provide you with detailed information and tips on how to design and build a subwoofer enclosure for your Silverado extended cab truck. Whether you are a car audio enthusiast or simply looking to enhance the audio quality in your vehicle, this guide will help you create a custom sub box that fits perfectly in your truck and delivers exceptional bass performance.

Understanding Subwoofer Enclosures

Before we dive into the blueprint and construction process, it is important to have a basic understanding of subwoofer enclosures. A sub box serves as a housing unit for the subwoofer, providing the necessary air space and structural support for optimal sound reproduction. There are various types of subwoofer enclosures, including sealed, ported, and bandpass enclosures, each with its own unique characteristics and sonic qualities.

Sealed Enclosures

A sealed enclosure, also known as an acoustic suspension enclosure, is a fully sealed box that provides a tight and accurate bass response. This type of enclosure is ideal for those who prioritize precise and controlled bass reproduction, as it minimizes the interaction between the subwoofer and the air inside the box.

Ported Enclosures

Ported enclosures, also referred to as bass reflex enclosures, feature a vent or port that allows the air inside the box to interact with the external environment. This interaction enhances the bass output and extends the low-frequency response. Ported enclosures are known for producing louder and more boomy bass compared to sealed enclosures.

Bandpass Enclosures

Bandpass enclosures are a combination of sealed and ported enclosures, featuring two chambers and a ported section. This design allows for efficient transfer of air and creates a narrow frequency range that emphasizes specific frequencies. Bandpass enclosures are popular in car audio competitions due to their ability to produce extremely loud and punchy bass.

Gathering Measurements and Specifications

Before you start designing your sub box, it is crucial to gather accurate measurements and specifications of your truck's interior. This will ensure that the enclosure fits properly and maximizes the available space. Here are the key measurements you need to take:

Truck Interior Dimensions

Measure the dimensions of the available space in your Silverado extended cab truck where you intend to install the sub box. Take note of the width, height, and depth of the area, as well as any obstructions or irregularities that may affect the box design.

Subwoofer Specifications

Refer to the specifications of your chosen subwoofer to determine the recommended air space requirements. The manufacturer usually provides guidelines on the ideal box volume and tuning frequency for optimal performance. These specifications will help you design a sub box that complements the subwoofer's characteristics.

Designing the Blueprint

Once you have gathered all the necessary measurements and specifications, it's time to design the blueprint for your subwoofer enclosure. This step involves creating a detailed plan that outlines the dimensions, shape, and construction details of the sub box. Here are the key factors to consider:

Enclosure Type

Based on your preference and the characteristics of your subwoofer, choose the type of enclosure that best suits your needs. Consider factors such as bass response, power handling, and available space in your truck.

Box Volume and Shape

Calculate the box volume required for your specific subwoofer based on its specifications. Determine whether a rectangular or irregular shape will fit better in your truck's interior and provide optimal performance.

Material Selection

Choose a suitable material for constructing your subwoofer enclosure. MDF (medium-density fiberboard) is commonly used due to its durability and acoustic properties. Ensure that the material is thick enough to minimize vibrations and resonance.

Port Design (If Applicable)

If you decide to go with a ported enclosure, carefully design the port dimensions to achieve the desired tuning frequency. The length, diameter, and shape of the port significantly impact the bass response and overall sound quality.

Constructing the Sub Box

With the blueprint in hand, it's time to bring your design to life. Here are the steps to construct the subwoofer enclosure for your Silverado extended cab:

Gather Materials and Tools

Collect all the necessary materials, including the chosen wood, screws, glue, and insulation. Additionally, ensure you have the appropriate tools such as a circular saw, drill, jigsaw, and measuring tape.

Prepare the Wood Panels

Using the measurements from your blueprint, cut the wood panels to the required dimensions. Take care to make precise cuts to ensure a tight and secure fit when assembling the box.

Assemble the Panels

Apply wood glue to the edges of the panels and secure them together using screws. Use clamps to hold the panels in place while the glue dries. Ensure that the joints are tight and sealed to prevent any air leaks.

Reinforce the Box

To enhance the structural integrity of the sub box, reinforce the internal corners with additional pieces of wood or braces. This will minimize vibrations and improve the overall performance of the enclosure.

Install the Subwoofer and Wiring

Once the box is fully assembled, install the subwoofer into the designated space and secure it using screws or brackets. Route the necessary wiring for power and audio signal, ensuring proper connections and insulation to prevent any electrical issues.

Seal the Box (For Sealed Enclosures)

If you opted for a sealed enclosure, seal any gaps or seams in the box using silicone caulk or foam gaskets. This step is crucial to eliminate any air leaks and maintain the desired air space.

Tune and Test the Subwoofer

After installing the sub box in your truck, it is important to fine-tune the subwoofer's settings and test its performance. Adjust the gain, crossover frequency, and phase settings to achieve the desired bass response. Conduct various listening tests to ensure optimal sound quality.


Designing and building a subwoofer enclosure for your Silverado extended cab truck requires careful planning and precise construction. By following the blueprint and construction tips provided in this article, you can create a custom sub box that perfectly fits your truck and delivers exceptional bass performance. Enjoy the immersive audio experience as you hit the road with your newly installed subwoofer!
