Current system. New system ideas/help.

So, I currently have a 2011 DX 1000.1 amp running at 2 ohm(1,036 RMS) 4 ohm(550rms). I have 2 CVR's that can't handle this amp so I want to upgrade. I'm thinking about an AA Havoc 15" because it can handle well over what my amp is putting out. But I would like to keep going down the line of two 12's because they have more cone area = louder. I 've started a few threads like this before but just don't know what to get or do, I'm so lost. I'll possibly get a new amp down the line, even though I already have 3 of them, why not add another one? Anyways, any ideas and help or suggestions would be wonderful. Thanks.
