Knowledge is Power
I felt the need to help you originally because I really like power hx2's. Then you insulted us. Don't insult members if your asking these questions to us. Your question is pretty basic and with the magnitude of your question you dont know all that much.//content.invisioncic.com/y282845/emoticons/bsflag.gif.21f42eccd34b7d1eb1608fb1b59b69c3.gifYou are correct in that you do not need 2000 watts to power anything. However, in order to get the Power HX2's loud you need that much. Think logically, they take 1000 RMS each. Usually you can go around 1200-1400 RMS per.
Now, I have 10's.
I guarantee I could make your car rediculouslly loud with what you have. Your problem is your box its that simple. Build a new one or buy one. Port it. They will do everything they arn't at this point. You have plenty of power anywhere from 500-750 those woofers will be loud and they will be reaching there potential. Granted these woofers can take tons more on burps but thats for competeing.
To answer the original question stay with the two woofers. Read above to know what you should do with them. And don't be a smarta$$ it won't get you very far here at all.
