Here Are My F150 Supercrew Subwoofer Box Plans:

Below are the methods you can use to build your custom subwoofer enclosure for F150 Supercrew. However, you don’t have to follow the exact dimensions for your custom enclosure plan because box dimensions may vary depending on the Ford F150 model year.

Building a Behind-the-Seat Subwoofer Box:

Follow the below steps to build the enclosure that you can place behind your F150 Supercrew Cab back seat:

1. Gather the Necessary Tools and Materials:

Before you begin the process, make sure you have the following tools:

• Medium-Density Fiberboard (MDF) or plywood
• Measuring tape
• Circular saw or jigsaw
• Screwdriver or drill
• Screws
• Wood glue
• Terminal cup
• Speaker wire
• Subwoofer of your choice
• Carpet or upholstery material (optional)
• Right subwoofer for you F150 Supercrew

2. Measure the Available Space:

Measuring the space behind your F150 Supercrew’s seats is critical for building a subwoofer enclosure that fits the available space. This helps you determine the maximum dimensions for your box and avoid any obstructions or irregularities in the area.

Determining this information beforehand will help you build an enclosure with adequate airflow and audio quality while still fitting in with your vehicle aesthetics. Proper measurements are vital to getting the best possible results from your new audio setup!

3. Design the Subwoofer Box:

Take adequate measurements to create a snug fit and sufficient clearance for both the subwoofer and any wiring that needs to be connected.

Consider the desired volume when designing, which will help provide a more optimal bass response. Finally, shaping is essential as it can also affect sound waves and how they interact with each other within the box.

With careful consideration of these factors, you should be able to construct a suitable subwoofer enclosure for your F150.

4. Decide the Cutout Area For Subwoofer:

To decide on the cutout area, follow the below steps:

• Check Subwoofer Specifications: Gather the subwoofer specifications you intend to install. Give extra attention to the subwoofer’s mounting depth, outer diameter, or any recommended enclosure volume requirements the manufacturer provides.
• Calculate the Cutout Diameter: You can quickly determine the cutout diameter by knowing the outer diameter of your subwoofer. Usually, I recommend making the cutout diameter slightly larger than the subwoofer’s outer diameter to ensure a proper fit. This allows for easy installation and accurate mounting of the subwoofer.
• Determine the Mounting Depth: The mounting depth of a subwoofer is the distance required to fit securely into an enclosure. Measure the available space in your installation area and compare it to the subwoofer’s depth to ensure enough room for proper installation without any hindrance from other components.

5. Cut the MDF:

To cut MDF or plywood, first transfer the measurements onto it and then use a circular saw or jigsaw to make the cuts. To make a subwoofer box for F150 Supercrew, you will need front, back, sides, top and bottom panels.

Wear protective gear like gloves and goggles when using power tools like a circular saw or jigsaw. When making your cuts with these power tools, keep even pressure on them for clean cuts, as extra pressure can cause splintering of wood chips at the end. Before beginning your project, you should also consider the location of any nails in the MDF or plywood.

6. Assemble the Subwoofer Box:

Start by applying wood glue along the edges of your subwoofer box panels. Then, join them together and secure them with screws or nails. Make sure to pay close attention to alignment and ensure there’s an excellent, tight fit between each panel.

Once all the panels have been assembled correctly, you can finish off any exposed edges with caulk or sealant for an attractive look. 

7. Carpet or Upholster the Subwoofer Box:

To carpet or upholster the subwoofer box:

1. Start by measuring the surface area.
2. Cut a piece of upholstery material in the same shape and size as your measurement.
3. Glue one side of the fabric to the dry subwoofer box, ensuring all sides are properly glued down.
4. Position the terminal cup and ensure it is secured to provide proper ventilation for your subwoofer.
5. Use additional glue to keep it firmly attached and give it a finished look!

Building an Underseat Subwoofer Box for F150:

Here are the steps that will help you build the under-seat subwoofer box for Ford F150 Supercrew:

1. Measure the Available Space:

To build the enclosure for your F150 Supercrew’s subwoofer, you must first measure the available space under the seat. Use a measuring tape to note down the length and width of the area you can work with.

Additionally, check for any obstructions or irregularities that may affect how much space is available or where and how you install the box. With this information, you can determine which type and size of enclosure best fits your needs.

2. Determine the F150 Under Seat Sub Box Dimensions:

The dimensions of an under-seat subwoofer box for an F150 can vary depending on the specific model and seat configuration.

Generally speaking, the height is around 3 to 6 inches (7.62 to 15.24 cm), the width typically ranges from 8 to 12 inches (20.32 to 30.48 cm), and the depth usually goes from 10 to 18 inches (25.4 to 45.72 cm).

You must measure your space carefully so the box fits your F150 comfortably without causing interference or discomfort for passengers in the backseat area. You need to make it down fire design.

3. Determine the Cutout Area of the F150 Underseat Enclosure for Your Subwoofer:

Follow the below steps to get the cutout area plan for your enclosure:

• Determine Subwoofer Specifications: You can check the sub’s specifications to determine its outer diameter and mounting depth. This information is usually included in the manual or the manufacturer’s website.
• Calculate Cutout Diameter: The cutout diameter for a subwoofer is calculated by taking the subwoofer’s outer diameter and adding a small margin, usually 1/4 to 1/2 inch. This extra space ensures proper fit and eliminates potential interference between the subwoofer and enclosure during installation.
• Determine Mounting Depth: When deciding the depth of the subwoofer, always provide enough space to fit into your custom enclosure without coming into contact with other components. Measure and compare the depth of your subwoofer to ensure it will fit properly.

From here, follow the steps 5, 6, and 7 that are mentioned for the behind-the-seat section.

What Is the Right Direction for the 2019 F150 Supercrew Subwoofer Box Behind Seat?

The recommended direction for placing a subwoofer box behind a 2019 F150 Supercrew seat is to position the subwoofer facing towards the vehicle’s rear.

This setup allows for better low-frequency response and distribution by optimizing sound waves bouncing off the rear wall. To find which orientation produces optimal sound quality, experiment with different placements and configurations until you find one that works best for your specific setup.

When installing your subwoofer box, ensure it is securely mounted to not interfere with any safety features or disrupt seat functionality.

According to my experience, positioning the subwoofer facing towards the rear will provide an enhanced overall sound experience that immerses listeners into its full potential without compromising safety or comfortability in any way imaginable!

Factors to Consider When Choosing or Building a Subwoofer Box for Your F150 Supercrew:

Here are some of the most important things that I suggest for F150 owners so that they won’t waste energy or investments in useless products:

• Available Space: As mentioned above, different model years of the Ford F150 Supercrew Cab require different dimensions for your sub-box. Therefore, you must consider the measurements under the rear seat, trunk, or any location where you place to place the sub. You must also ensure that the box dimensions fit within the allocated space without obstructing other components or compromising passenger comfort.
• Subwoofer Specifications: This is one of the most critical factors when planning your subwoofer box. Understanding the sub’s specifications, recommended enclosure type, and dimensions will help you build the powerful truck audio system. 
• Enclosure Design: You must consider the enclosure design for optimal audio quality and performance. The sealed box is excellent for tight, accurate bass response; ported box produces louder output and deeper bass; the bandpass box gives the highest possible production with mid-bass emphasis.
• Construction Material: When choosing a construction material for your F150 Subwoofer, consider Medium-Density Fiberboard (MDF). It has proven strength and acoustic properties. Additionally, it is durable, resistant to vibrations, and can give your subwoofer the solid foundation needed for optimal performance. Choosing MDF offers these benefits and more.
• Box Construction: When planning a custom box for your F150 Subwoofer, consider the box construction carefully. Proper techniques like joining panels with screws, applying wood glue, and reinforcing critical areas are necessary to ensure stability and durability. You may also need bracing or internal supports depending on the design and requirements of the subwoofer.
• Air Leaks and Internal Damping: Enclosure air leaks can reduce overall performance, so sealing all joints and openings using silicone caulk or gasket tape is essential. Adding internal damping materials like polyfill or foam will also improve audio quality by reducing internal resonances within the box.
• Safety and Vehicle Considerations: Safety should be a top priority when installing a subwoofer box in your F150. The box must be securely mounted to ensure it doesn’t move while the vehicle is in motion. The subwoofer box must also not interfere with safety features like seat movement or visibility.
