How to Build a Subwoofer Box for Two 10 Inch Subwoofers (8 Steps)

By Nichole Liandi

If you want to add some bass punch to your vehicle, a pair of 10-inch subwoofers can put the audio firepower you're looking for into your car. Two 10-inch subs provide plenty of surface space to move the air you need for big bass. An important part of the system is a solid, well-constructed box to house the subs. With basic materials and tools, you can build a box that'll complement your subs and let them do their work.

Step 1

Measure and cut two end panels from the MDF with a circular saw. The panels should measure 14 by 14 inches.

Step 2

Measure and cut top and bottom panels from the MDF with a circular saw. The panels should measure 14 by 28 inches.

Step 3

Measure and cut front and back panels from the MDF with a circular saw. The panels should measure 13 by 28 inches.

Step 4

Assemble the top, bottom, front and back panels together to form a hollow box. Overlap the pieces so the dimensions measuring around the box are 14 by 14 inches. Screw the pieces together with wood screws, spaced every 3 inches.

Step 5

Place the end panels onto the box and screw them in place with wood screws spaced every 3 inches.

Step 6

Cut two openings in the front panel of the box for your subwoofer. Space the openings so they are equidistant top to bottom and side to side.

Step 7

Drill two 1/4-inch holes in the back of the box, centered on the openings in the front. Feed a piece of speaker wire into each hole from the outside. Reach inside the box from the front, grasp the wires and pull them out the front openings.

Step 8

Connect the speaker wires to your subwoofers. Place the subwoofers in the openings and screw them into place.
