A: The manufacturer should have suggestions on all of that or they can be found in the spec sheets/manual for the subs.

Any subwoofer that has at least a 400RMS rating( if using Two Subs
Or 900RMS handling if running only 1 Sub
Becarefull on the Ohm impendence of the sub(s) since the Amp you have is 4ohm mono stable
So if two subs use a dual voice coil 4ohm
If a single subwoofer being used use either a single 4 ohm or a 2 ohm dual voice coil
