I'm looking at installing some better speakers in my sedan, and from crutchfield, I'm seeing that 6.5" in front, and 4" in rear is what I need. I did a search adn found that people have had some problems installing them.
What are some good ones, what are components, and should I get a separate amp if I'm still using the factory head unit (I like the 6-disc). I figure I'd go with something really nice for front, then decent in back. not sure if I'll ever add a sub at this point. With better speakers I won't have to.
