The AV can take over 1500wrms. If the box is a high Q (small sealed), you can shove in the power. Only reason why i say this is to prevent bottoming out of the sub. If in a ported box, you could also shove in a lot of power.. just don't turn up any of the "bass boosts". As long as the gains are set correctly, and no bass boosts.. you should be fine with that horrible amount of power.
