It is going to be a matter of personal preference and what sounds good for the type of music you listen to. Best thing to do is go to a couple different car audio stores..(not best buy) and listen to the different speakers with your type of music. I personally like MB Quart, Rockford Fosgate, and JL Audio for the types of music I listen to. For amps, you can never go wrong with PPI, ADS amps though you will pay for them, if you are on more of a reasonable budget give punch amps by rockford fosgate a try.
