They're 2 ohm SVC (single voice coil)

Basically if you wire them in series, like in the pic that you posted, you double the impedence that they are rated at, 2ohm up to 4ohm. Reliable and efficient but you don't get many watts. If you wire them in parallel you halve the impedence, 2ohm down to 1ohm. Lots of watts but inefficient and prone to overheating. Some amps are 1ohm stable but its still inefficient.

Youre best bet in my opinion is to get two 4ohm subs and wire them parallel to get it down to a 2ohm load. Plenty of watts, efficient and reliable.

Stick with SVC if you had trouble with that. DVC is a bit more complex.

So basically series = double ohm load
parallel = half ohm load.
