X20D would be a decent choice. The X40 was reviewed in the newest CA&E and it produced slightly more power than what it's rated at. Got good marks all around.
Another option would be the Pioneer Premier PRS-D2000. I auditioned the 720PRS comps running of this amp and I was very impressed.
If you want to save a lot of money and don't mind refurb and can live with a larger amp, check out the Kicker KX450.2
