Going by the specs you posted...use one sub with that amp. Wire the coils in parallel for a 2 ohm load and you will get RMS to it.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

The only recommended way to wire two subs to this amp is a series / parallel connection and let the amp rest at 4 ohm mono. The amp will not dissappoint with this "little" power at all. A better match of subs to the amp or amp to the subs would be preferred but work with what you have for now. Stevdart nailed suggestion #2. Here is how to safely wire this system.
