I don't know that 1 12 inch CVR is going to turn heads, but a good amp to get for that sub would be a mono channel 400 or 500 watt Kicker amplifier.
As long as the amp rms between 300 and 500 watts you should be good to go. Don't get junk ie: Pyle, Legacy, Boss, American Pro, Lanzar, Sony, JVC, etc.
Stick with Kicker, MTX, Alpine, JL, Pioneer etc for amps.
If I were you I would get the CVX instead of the CVR. You would probably want around a 800 watt amp for that though.
Hoped this helped.
