rockford sub and amp question

That shows the coils in series - 4 ohm impedance. I didn't look real close at the specs so you may want to check and see what the amp output is at 4 ohms.

The main parameter is impedance. The impedance of the speaker should match the impedance of the amp. Speaker impedance can be higher, but you lose some volume. If speaker impedance is too low, you run the risk of damaging the amp. In this case, since the amp will handle loads down to 2 ohm, you will be OK.

As long as the speaker is rated for the same or more power as the amp, you are OK. Unless you plan on using a bigger amp later on, no need to buy a speaker with "excess" power handling capabilities. But it doesn't hurt anything either - assuming the speakers have the same efficiency (being from the same line from the same manufacturer, they should be close), they will all put out the same volume per watt.
