Bump because I don't have time to look stuff up right now the other guys on here will def throw some suggestions at you. There is no "Best" sub/amp combo as a matter of fact most 2 members on here will have completely different suggestions based off personal opinions. The good news is that there are many good options and we'll give some to you our main job is to aim you away from bad decisions like that other setup. for $250 total you should be able to wind up with a pretty decent setup. You should be able to get a setup that is much louder and cleaner then the audiobahn sony setup.
