I've seen them 3 different ways:
1) the female connector is attached to the sub cabinet and the drivers are wired to it; the wires from the A370 pass through a hole in the amp box and have the male connector hooked directly to the A370 wires; then to plug it up just insert the male connector into the connector on the speaker cabinet and twist to lock.
2) the female connector is mounted to the amp box and connected to the A370 wires; the hook up wires to the drivers are made long and the male connector is attached to them; then to plug it up insert the male connector from the speaker wires into the female connector on the amp box and twist
3) attach a female connector to the sub cabinet and connect the drivers to it; connect a second female connector to the amp box and connect the A370 wires to it, then make up a separate cable with a male connector on both ends. Connect the amp and cabinet with the interconnect you just made.
When you buy the kit from Danny you get enough connectors for method 1 or 2. If you want to do method 3 you will need more connectors.
As Rich said, all the Neutrik connectors have to be 4 pole, 2 for the driver coil and 2 for the servo coil.
