If you have other options, i'd go with a class D amp for the sub. I've seen Phoenix Gold 400.1 Class D amps for 150 on ebay. You'd be better off with that than a class a/b amp simply because class D are much more effecient, and also they allow 1,2,4 ohm settings and still put out the same power.
I have one, and people ask me where the hidden sub is.
class d's are generally only more efficient before full output - they do well until you get them to make full power - at that point they rival the best class a/b's.
generally they are good from a $/watt standpoint!
