Overview of F150 Sub Box Under Seat

F150 Sub Box Under Seat

The sub box under the seat in an F150 is designed to enhance the audio experience within the vehicle. It provides a dedicated enclosure for a subwoofer, allowing for improved bass response and overall sound quality.

The primary benefit of having a sub box under the seat is its space-saving design. Unlike traditional subwoofers that occupy valuable cargo or cabin space, the under-seat sub box utilizes the otherwise unused space beneath the front seats. This allows for a more discreet and integrated audio system without compromising on performance.

However, it’s important to note that under-seat sub boxes may have limitations compared to larger, more traditional subwoofer enclosures. The compact size of the under-seat box can restrict the size and power handling capabilities of the subwoofer that can be installed. Additionally, the placement of the subwoofer under the seat may affect the sound dispersion and frequency response, resulting in a less optimal bass experience compared to larger enclosures.

Comparison to Other Sub Box Options

In comparison to other sub box options available for the F150, the under-seat sub box offers a unique combination of space efficiency and sound enhancement. While larger, traditional subwoofer enclosures may provide better overall performance, they require more space and may not be suitable for all applications.

Another option to consider is a behind-the-seat sub box. This type of enclosure mounts the subwoofer behind the rear seats, offering a compromise between space efficiency and performance. Behind-the-seat sub boxes are generally larger than under-seat boxes, allowing for the installation of larger and more powerful subwoofers. However, they may still require some cargo space for installation.

Ultimately, the choice between an under-seat sub box and other options depends on individual preferences and requirements. Those seeking a discreet and space-saving solution may find the under-seat sub box to be an ideal choice, while those prioritizing performance may prefer larger, more traditional enclosures.

Choosing the Right Subwoofer for F150 Sub Box Under Seat

Selecting the ideal subwoofer for the F150 sub box under the seat involves careful consideration of several factors. These include the subwoofer’s size, power handling capabilities, and sound quality preferences.

Subwoofer Size

The size of the subwoofer is crucial as it must fit within the designated space under the seat. Compact subwoofers with a diameter of 8-10 inches are typically suitable for this application.

Power Handling

The subwoofer’s power handling capacity should match the output of the amplifier that will be powering it. For optimal performance, choose a subwoofer that can handle the amplifier’s maximum power output.

Sound Quality

The sound quality of the subwoofer is subjective and depends on individual preferences. Consider factors such as bass response, clarity, and distortion levels when making a selection.

Recommended Subwoofer Models

  • JL Audio TW3-8W3v3: A compact 8-inch subwoofer known for its exceptional sound quality and bass response.
  • Alpine SWS-8D4: Another compact 8-inch subwoofer that offers a balanced sound with deep bass and clear mids.
  • Rockford Fosgate P3SD2-8: A 10-inch subwoofer with a powerful sound and high power handling capabilities.


When choosing a subwoofer, it’s important to consider the trade-offs between different options. For instance, a larger subwoofer may provide deeper bass but may take up more space. Similarly, a subwoofer with higher power handling may require a more powerful amplifier.

Tuning the sub box under the seat is crucial for achieving optimal sound quality from your audio system. Proper tuning ensures that the subwoofer blends seamlessly with the rest of the speakers, delivering a balanced and immersive listening experience.
