A component set consists of, tweers (2), mid range drivers (2) crossover (2). If you get a component system, you will not be able to use the bose tweers, they suck anyways. Just replace it all. Though i agree that you get what you pay for, to an extent. Try, cadence. They are awesome quality and fairly priced. You will need another 4 channel amp to power the comapnents. 400-500 watts would suffice. Some one siad that they had 5 1/4 front door speakers. My 07 has 6.5 front and 5 1/4 rear. I had the bose system as well.
Once again, how are you running power to your current amp? What gauge copper did you use? Have you upgraded the electrical sstem in any way?
