Building the Enclosure
Determine the dimensions of your enclosure.
Be certain the box dimensions that you have designed will fit in the location you
have chosen in your vehicle. Sometimes making a cardboard box with the same
outside dimensions is helpful.
It is recommended to use
%
inch thick MDF (medium density fiberboard) for your box.
Use a
"T"
square to verify precise right angle cuts before you assemble the box.
Use high quality wood glue and screws to assemble the box to guarantee an airtight box
that will not come apart due to excess vibration and pressure.
It is recommended for sealed enclosures to stuff the interior of the box about
50
-
75%
fiberglass insulation or Dacron fiberfill for increased sound damping and woofer performance.
For ported enclosures, it is recommended to staple
1"
thick fiberglass insulation to the
interior walls of your box.
Use slide on connectors for spade style connectors or bare wire for push and screw
terminals. Do not solder the wires to the factory connectors as this may cause damage to the
voice coil or tinsel lead and may void your warranty.
