What would be better for me? Coaxial or component car speakers?

[dyno_05]

I was looking at upgrading the speakers. I was looking at the best buy one's. IDK if they do the installs thou. They used to at the future shop i remember. I can prob find a shop that does it if not easy in my city.
I was thinking just getting coaxial as i can keep the radio (kicker speakers have good review, i think 6.5"). If I go component id need to replace the radio most likely. IDK if replacing the radio will mess things up like the steering wheel buttons or something else the radio controls. I like those. I kinda don't want to be the guy shaking the neighborhood ether that is another reason I may go coaxial. Just want something that sounds a bit better. If it's that much better maybe put out the extra couple hundred of dollars.
Got a Crystler 200.

Generally speaking, a component design is better than a coaxial design.
Many component speakers come with a passive crossover, so you will not need to replace your stereo.
If you replace your stereo, you will need an adapter, if they make one for your car, to keep your steering wheel buttons working the same way.
