Very good information posted above about the intended use of the three different type of speakers.

Now, as was asked, what is your budget and what year/make/model vehicle do you have? Chances are one of us has done many different types of setups for different budgets over the years and can tell you exactly what will sound good and what won't. Here in Land O Lakes, I think we have installed equipment in every pickup ever made. Hell, I can tell you what sounds good in a tractor-from experience!
