1: This enclosure is designed so that the sub fires through the pass through hole of the rear bench seat. First construct the front of the box from 3/4-inch MDF, using wood glue and nails to fasten the pieces together.

2: Use plenty of supporting pieces of MDF, such as the reinforcing squares in the corners of the bottoms and the angled pieces supporting the top.

3: The step up on top will hold the 6x9’s that will fire through the rear deck.

4: Seal the box with silicone so that it’s airtight.

5:  Cut a baffle board to fit your subwoofer.

6: The front side of the baffle board will be visible, so Jay wrapped it in gray carpet. To firmly attach the baffle to the enclosure, Jay used aluminum L-bar.

7: For the back, Jay cut pieces from 3/4-inch MDF and layered them double thick.

8: Mount the subwoofer, filling in the airspace with batting.

9:  When everything is mounted, you can see the subwoofer through the pass-through to the trunk. The gray carpet covers up the MDF.

10: Seal up the back of the enclosure with another piece of MDF. Screw securely. Note the square Jay drew on the back to mark where the is located.

11: To this piece of MDF, Jay mounted the amplifiers and capacitors for the system using the supplied hardware.

12: This location is within easy wiring distance to the battery.

13.  The finished enclosure viewed from the cabin.

14: The entire enclosure hides behind a trim panel of  ½ -inch MDF carpeted to match the rest of the trunk.
