What kind of subwoofer does this fit?
This enclosure is precision-built for a single standard 8" round subwoofer. The cutout diameter is exactly 7.125" (7-1/8").

Will it fit in my vehicle?
Yes, it features a practical daily footprint that maximizes output while keeping a space-conscious profile in your trunk or cargo area. The exact external dimensions are 24" W x 9" H x 13" D.

How is the performance and wiring?
Designed as a true high-end, custom-ported specification, this cabinet steps far out of the lane of generic boxes. It is precision-engineered with a custom slot-port tuned to 34Hz to deliver incredibly deep, aggressive, and highly efficient low-frequency extension tailored perfectly to high-performance round 8-inch subwoofers. It features an upgraded 2" round nickel-plated binding post for secure and reliable wiring connections.

   

PreFab™ Custom-Spec Series: The Off-The-Shelf Custom Enclosure

   

In the car audio community, off-the-shelf boxes usually mean thin panels, generic tuning, and choked output. We developed the LAB PreFab™ Custom-Spec series to completely rewrite that narrative. Proudly manufactured in the USA, this series delivers true custom-shop acoustic performance without the custom-shop price tag or wait times.

   

Each cabinet is precision-cut from solid high-grade MDF and engineered around a highly optimized, high-velocity custom slot-port design. Instead of generic calculation curves, these enclosures are built around real-world manufacturer specifications to ensure proper port area, maximum flow, and ideal airspace matching. It is the ultimate plug-and-play solution for audiophiles and daily bassheads who refuse to compromise on custom-level low-end extension.

        

The Custom-Spec Advantage:

   
           
  • True Custom Slot-Porting: Engineered with optimized port areas and precise tuning to replicate custom-shop low-end extension and power handling.
  •        
  • American Made Solid Build: Designed, cut, and assembled in the USA using high-grade CNC-cut MDF to ensure maximum acoustic efficiency.
  •        
  • Manufacturer-Spec Airspace: Built closer to specialized manufacturer parameters than any generic box on the market—ready to ship, ready to slam.

Good fit, good construction.
Style: CA12289
This filter was a good fit for my Corolla. It appears to be well made. The gasket is resilient and looks like it would seal well, preventing any leakage past the filter. Construction was good, with no holes or gaps in the filter paper itself. Unfortunately, the buyer usually has no way to judge the performance of an air filter, and I'm no exception, so I can't say how effective it is in actually removing dirt from the air going into the engine. But I would buy this filter again.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.
