for example...

The alpine sub you have, you say is 4ohmDVC. Meaning it has 2 voice coils. (4 terminals on the back of the sub) you can wire these voice coils in different ways.
Wiring them in series or parrelell will give you a different resistance (ohm) on the amp.

When you look at amp ratings, it MAY say, 500wrms@4 ohm.
700wrms@2ohm.

you buy the approprate sub(s) to give you your desired load (thats the ohms value) on your amp.

so if you have 1 4ohmDVC sub, and you want to put a 2ohm load on this particular amp, wire it thusly,

if you want to put a 4ohm load on the amp, you will need to have a 2ohmDVC sub,

its usually half the max power. If he keeps the gain low it should be ok, will be a waste of a good amp though imo.
