Our take on the Q-Customs Factory-fit Subwoofer Enclosures


Designed to give you factory fit and finish plus great sound and durability, this Q-Customs enclosure by Q-Logic holds one 8" Type 1 subwoofer and fits under the driver's side rear seat, without sacrificing any space. (Note: the bottom seat cushion will not fold over once this enclosure is mounted beneath it.)

The photo shows how well this enclosure integrates with the interior of your vehicle. It looks like original equipment, but gives you deep, pounding bass no factory sound system can touch. Internal volume is 0.35 cubic feet.

Please check with us before purchasing by using the vehicle selector on our site, or calling a Sales Advisor at 1-888-955-6000 to verify fit information. Choose the color that matches the model year of your vehicle.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Compatibility: The enclosure is roughly wedge shaped with a "green" plastic front faceplate, and it`s bottom is contoured to follow the shape of the floorboard (driver`s side rear) in 97`-98` Ford F-150 extended cab trucks. The "green" plastic fascia is colored to match the "green" interior found in some 97`-98` F-150 extended cab trucks. Check the Install Guide for applicable vehicles.

Note: The bottom seat cushion will not fold over once this enclosure is mounted beneath it.

Cosmetics: The enclosure front is finished with a "green" molded plastic fascia plate with a wrinkled surface pattern . The main body of the enclosure is made of particle board covered with medium grey/black box carpet. The enclosure has an integrated molded black plastic base that is shaped to allow the enclosure to follow the floorboard contour of the above mentioned vehicles.

Wiring: The input terminals are gold plated 5-way binding posts with plastic wire retaining nuts. The wire supplied to connect the terminal cup to the woofer is terminated at both ends with 0.210" female quick slides.

Replacement bolts: Four replacement bolts are provided to take the place of the original Ford factory driver`s side rear seat  hinge bolts (the Ford bolts are longer than necessary and, if not replaced, would damage the top of the enclosure).


  • Internal volume: 0.35 cu/ft.
  • Maximum speaker frame diameter: 8.768"
