Key Features

BOX DEAL! Kenwood KFCWPS1200F 12" 1400W Car Subwoofer and Sealed Enclosure - In Phase Car Audio BX12SL

Choosing a bass box can be hard as not many people sell them and ideally they need to be built by people who know subwoofer parameters, box design and understand how sound waves travel. Not to mention, have joinery knowledge.
Our expertly designed boxes will fit into a majority of vehicles. Our box's panels are 20mm thick and we use high density MDF only for enhanced durability. This enables the box to have a long life and great bass performance.
When shopping online for a box, be careful. A lot of boxes will be advertised for £15-£35 and are often made from inferior MDF and unsustainable sources. Not to mention, sealed badly. This kills off the tight accurate bass you are seeking
The Kenwood KFC-WPS1200F leaves no room for compromise. This sub is perfect for a sealed enclosure and the bass response is next level. Kicking out 400W RMS, there is a plenty of power to be had.
High Quality Carpet 
The Soot Black carpet has high grade fibres commonly found in industrial carpet used in offices and schools, whilst maintaining a soft to touch texture. This compliments the expert box design to go with it.

MDF Like No Other

The box structure is fabricated from high density MDF that has similarities to high end laminate floors. Made for performance without compromise. Enjoy tight bass in your car with a proper made box.

Binding Post
The binding post is made from high quality plastic will metal terminals plated with a gold finish.

Instead of loose and unstable sounding bass, you can have softened bass that sounds amazing thanks to the synthetic filling.

Sealed Box
The sealed technology allows a tight bass output instead of a loose and unfiltered bass output. This allows accurate bass as well.
