You cant go wrong with a Pioneer head unit. I would go with either the 3rd or 5th choice. As far as speakers I would save money and get component speakers. They sound better and clearer than regular speakers. I have a pioneer head unit and I have infinity door speakers which do the trick cause they have adjustable tweeter. But go with a component speaker cant beat that. I eventually will do the same and move my infinities to the back doors.
