Why Autobahn? Im running 2 Rockford Fosgate 15's. And i have very good sound and bumps. What rating are the subs your getting? How many Ohms and so forth. As for amps I would save my money and get a rockford,jbl,apline or eclipse amp. Dont waste your money on crappy parts. Why spend the money twice? Do it right the first time. Saves money in the long run.
