Building the Enclosure

Determine the dimensions of your enclosure.
Be certain the box dime

nsions 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 .75* inch thick MDF (medium density
fiberboard) to build you speaker

box.
Use a "T" square to verify precise right angle cuts before you assemble
the box. Use high quality wood glue and screws to assem

guarantee an airtight box that will not come

apart due to excess vibrati

ble the box to

on and pressure. It is recommended for sealed enclosures to stuff the
interior of the box with approximately 50% Dacron or Polyester
fiberfill for increased sound damping and woofer performance.
For ported enclosures, it is recommended to staple 1" thick Dacron or
Polyestrer 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.

Recommended wiring

The following page will give you a few different options to match the
impedance of the woofers to the impedance capability of the amplifier.
