A previous purchase of some car audio equipment left me in need of an enclosure for a Kicker subwoofer. Rather than buying a pre-fabricated box, I decided to build my own.

Unfortunately, I didn’t document the process, so excuse the lack of pics.
The box was constructed of 5/8″ MDF, and I drew up plans using AutoCAD to roughly accommodate Kicker’s recommended internal space for this model. The pieces of the box were glued up, brad nailed and upholstered, minus the side panels which were done last and then press fit in. Bracing was then added within, as well as a bead of silicone along all seams to eliminate any potential air leaks.

Although difficult to see in the picture, the side of the box features an embossed logo. This was achieved by cutting out the design in thin card and gluing it to the MDF panel before upholstering. Working with such a thin material, the design easily shows through – this also goes for any imperfections in the box however, so a good onceover should be given before applying the fabric. Body filler or wood filler can be used to touch up trouble spots.

Second time around, I’ll add a port. Otherwise, it came out nicely.
