Sure you can....wire the VCs in series for 8ohms //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
But seriously, you can wire only one VC, but that's not recommended because it will change everything about the sub. The recommended box sizes will no longer be right, etc etc etc.
So pretty much your options would be to wire the coils in parallel for 2ohm mono (which the amp can't handle), wire them in series for 8ohm mono (which wouldn't give a whole lotta power out of the amp), or buy a 2 channel amp and put one coil on each channel.
