To get the maximum performance from a single 10” woofer, this enclosure is designed so that it works best with the seat bottom folded down.  Notice that:

  • the top of the enclosure has been designed to following the contour of the seat bottom
  • a small distance is left between the cone of the subwoofer and the seat bottom
  • the subwoofer mounting baffle is on a slight angle
  • the front of the enclosure has an exit for the output of the subwoofer when the seat bottom is folded down on top of the enclosure

This creates a horseshoe shaped slot.  Slot loading the subwoofer provides a substantial gain in output when compared to conventional under-seat enclosure designs that simply fire the subwoofer up into the seat bottom.


When it comes to vehicle specific enclosures, nobody does it better than Q-Logic.  Our Q-Customs line of subwoofer enclosures has more offerings than any other company!  Given that, it’s quite likely that we have an enclosure to suit your needs.  In addition, we’ve been in the vehicle specific enclosure business longer than anyone else – since 1993.


Q-Customs Enclosures represent the state of the art in subwoofer enclosure manufacturing.  Since many Q-Customs enclosures go in incredibly tight spots, like behind interior panels and under seats, it is not possible to build them entirely out of MDF.  Using a hybrid of MDF and vacuum formed plastic panels allows us to increase the available interior volume of the enclosure without increasing its external volume.

Vacuum forming allows us to make incredibly strong, thin, and lightweight enclosure parts that allow Q-Customs to fit the contours of even the tightest of spaces.  Q-Logic brought vacuum forming technology to the subwoofer enclosure business in 1993.  Over the years, we’ve put what we’ve learned to work to provide the best vehicle specific enclosure that you can buy.

custom fit

In order to be called a Q-Customs Enclosure, these vehicle specific enclosures have to sound GREAT – just like our standard Q-Enclosures do.  Since Q-Customs Enclosures are designed to fit in tight spaces, they are all of the Type 1 variety.  When loaded with the subwoofer of your choice, expect the same great performance that our standard Type 1 Enclosures deliver!

Many of our customers choose a Q-Customs Enclosure when they want the addition of a subwoofer to their vehicle appear like it was installed from the factory.  Q-Customs Enclosures are offered in a number of factory-matched colors so that they blend in with the vehicles’ interior quite nicely.  In many cases, we use a combination of carpeting and factory matched coloring to achieve that factory look.

It is our intent to ensure your satisfaction after the sale.  To that end, we make ourselves available to you should you have any questions at any point in the process. This product is BRAND NEW IN BOX and is not refurbished in any way.
