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 .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 assemble the box to guarantee an airtight box that will not come apart due to excess vibrati 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. Please read and follow the diagrams closely to insure maximum woofer performance.
