Ford F150 Behind Seat 24-25

QUICK DEFINITION
A "Behind Seat" subwoofer enclosure for the 2024-2025 Ford F-150 is a specialized audio solution engineered to fit into the limited recess between the rear cabin wall and the back seat. Unlike universal boxes, these are CNC-cut to contour around the 2024+ specific obstructions (like the relocated factory amplifier) and utilize shallow-mount driver technology to deliver deep bass without compromising seat functionality or passenger legroom.

Ford F150 Behind Seat 24-25 Buying Guide

The 2024 and 2025 Ford F-150 introduced a significant challenge for audio enthusiasts: a redesigned rear cabin wall with relocated factory components (amplifiers and modules) that makes older "universal" truck boxes obsolete. Standard enclosures simply won't fit without permanent modification or loss of seat function. This collection solves that problem with vehicle-specific, direct-fit enclosures designed to nest perfectly into that dead space, restoring the low-end punch missing from the factory B&O or base audio systems.

Choosing the Right Solution: 10" vs. 12"

In a "behind seat" application, depth is your most valuable currency.



The Single 10" Route: This is the gold standard for "Invisible" audio. A 10-inch driver, like the JL Audio TW3 or Kicker CompRT, typically requires less air space (internal volume). This allows the enclosure to be smaller, ensuring the rear seat locks back into place effortlessly with zero resistance. It produces tight, punchy bass ideal for rock, country, and pop.



The Single 12" Route: Historically, putting a 12 behind an F-150 seat meant sacrificing seat travel. However, with new "Ultra-Shallow" technology—specifically from Wavtech—you can now fit a 12-inch cone in the same depth as a 10. This moves significantly more air, providing deeper sub-bass extension (rumble) preferred for hip-hop and electronic music.

Technical Features: The "Shallow" Revolution

To fit massive sound into a 3-4 inch deep box, these loaded enclosures rely on advanced engineering, not just smaller magnets.

  • Concentric Suspension (JL Audio): The 10TW3-D4 uses a specialized structure where the spider is placed inside the voice coil, compressing the mounting depth to just 3.25" while maintaining long excursion.
  • Oversized Voice Coils (Wavtech): The ThinPro 12 utilizes a massive 5" voice coil. This allows the magnet to sit around the coil rather than behind it, reducing depth to a shocking 3.0" while handling 750W RMS.
  • All-Weather Design (Kicker): The CompRT series features UV-resistant cones and weather-proof surrounds, making them durable enough for work trucks that might see dirt or moisture when seats are folded up.

Installation Advice

These units are "Loaded Enclosures," meaning the subwoofer is pre-installed and wired internally. Installation generally requires:

1. Removal of the factory rear wall carpet/padding (in some trims) to gain an extra 0.5" of depth.

2. Relocation of the factory jack kit (often moved to under-seat storage).

3. Wiring to an external amplifier (the factory radio power is insufficient for these drivers).

COMPARING MODELS
Series / Model Best Application Sound Profile Power (RMS)
Kicker CompRT 10" Budget-Friendly / Daily Driver Punchy & Aggressive 400W RMS
Wavtech ThinPro 12" Max Output / Deep Bass Deep Extension (High Air Movement) 750W RMS
JL Audio 10TW3-D4 Sound Quality (SQ) Audiophile Tight, Accurate, Warm 400W RMS
INSTALLER'S TAKE

For the 2024+ F-150, always test the "seat fold" immediately after placing the box but before bolting it down; if the seat back feels tight, you may need to trim the rear cabin carpet padding to gain that critical ¼-inch of clearance.

Frequently Asked Questions

Will these subwoofers fit the 2024 F-150 PowerBoost (Hybrid) model?

Yes, most behind-seat enclosures for the 2024-2025 F-150 are designed to clear the hybrid battery vents located under the seat, as the enclosure mounts to the rear wall. However, always double-check the specific product fitment notes regarding the Pro Power Onboard inverter location.

Can I power these loaded enclosures with the factory Ford amplifier?

No. While the 2024 F-150 B&O system has a factory subwoofer channel, it only produces roughly 50-100 watts. These aftermarket enclosures require 400W to 750W RMS, necessitating the installation of a dedicated aftermarket mono amplifier.

Why choose the Wavtech 12" over the JL Audio 10"?

Choose the Wavtech ThinPro 12" if you prioritize volume and deep sub-bass rumble (SPL), as its larger cone area and higher power handling (750W) move more air. Choose the JL Audio 10" if you prioritize accuracy, musicality, and tight transient response (SQ).

What happens to the factory jack when I install this box?

In most 2024+ F-150 behind-seat installations, the subwoofer enclosure occupies the space where the factory jack is stored. You will typically need to remove the jack and store it in a generic bag under the rear seat or in the truck bed tool box.

Do I need to cut metal or modify my truck to install these?

Generally, no. These "Direct Fit" enclosures are designed to utilize existing bolt points or friction fitment behind the seat. You may need to remove the rear wall insulation carpet or relocate the tire jack, but structural metal cutting is rarely required.
