If you shop around online, you will come across many of what we call “Pre-Fabricated” subwoofer enclosures. Some that you run across are vehicle specific and others are for simplicity of adding bass to most modern vehicles in a compact fashion. While these work great for most average consumers, online basshead shoppers and SPL competitors that want more than average bass were stuck purchasing raw subwoofers and finding a qualified enclosure builder to build them an enclosure. While this is an option, most of the time its hard to find someone that really knows what they are doing to optimize your raw subwoofers to the max.

So Kicker decided to build the perfect loaded subwoofer enclosure for those that want an extreme amount of bass but engineered to deliver maximum performance from the subwoofers. This is hands down, the most extreme loaded enclosure we have ever seen and will for sure put a huge smile on bass heads around the world. Here are a few key points about this enclosure and what makes it “bass head certified”:

  • The port is flared perfectly and tuned to 31Hz for some serious bump – without the expense of a custom enclosure.
  • Heavy, birch-veneer plywood construction, and thick internal bracing keep the enclosure stable, even under extreme SPL levels. Covered in durable black carpet and custom embroidered with the KICKER logo.
  • The QL7R12 is pre-wired to a pair of Two-Ohm terminals. All you need is an amp!
  • With 2,400 watts of RMS power handling, this computer-designed basshead subwoofer system makes rattling your ride easier than ever!


The subwoofers chosen for this amazing enclosure are the Kicker 12-inch Square L7R Series. They did not just select a random subwoofer or pick these based on what would look best. No, they chose the L7R series for their reliability, displacement of the square cone and the power handling these subwoofers can deliver. From the signature red stitching to the braced rear subwoofer frame, these subwoofers are built for delivering an insane amount of bass. Here are a few key features these subwoofers offer:

  • UniPlate™ solid pole piece & backplate construction ensure the sub stays cool, even under extreme power loads
  • Full 360-degree back bracing keeps the entire cone strong and stable for smooth, distortion-free bass.
  • Signature red stitching binds the ribbed Santoprene® surround to the injection-molded SoloKon™ cone for added strength, even under extreme stress.
  • KICKER’s L7R Square Sub technology gives you up to 20% more cone area than a round sub.
  • Dual voice coils come standard on all L7R models, for ultimate wiring flexibility. Get the highest possible power out of your amp.
