Design Features

KDC-12 KDC-15

• 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 ¾ 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.

The following page will give you a few different options to match the impedance of the woofers to the
impedance capability of the amplifier. Please look and follow the diagrams closely to insure maximum
woofer performance.
