Assembly:
Glue components to the correct positions on the board (hot melt glue works great). Secure inductors with non metallic cable ties. Solder components leads to the pads on the bottom of the board. Attach wires from input and drivers to the crossover. Insert standoffs into the bottom of the board at the four corners and mount the crossover to the enclosure.
