If they are 2 ohm dvc, and are 2000 watt's rms you will need an amp that puts out around 4000 watt's rms times 1 at 4 ohm's. I don't know an amp that big of hand sorry. What is the specs for that 1300 audiobahn?
Too expensive, you won't find a decent amp that will power those subs without paying thousands of dollars. If you were to spend all that money to power those subs, you'll eventually wonder why you did in the end with the results you'll get. Those subs are heavily overrated and inefficient. The cheapest good $300 amp that is powerful is the JBL 1200.1, so you'll need subs that work around that.
