6x9's

What are some good 6x9s to replace the factory ones?
And what exactly is a tweeter or what does it do?

a tweeter produces the higher notes in the music

some good ones are made by alpine, infinity, jl audio, focal, mb quart, and many other companies....tell us your price range and how many speakers you need. some companies to stay away from: audiobahn, sony, kenwood, and many other companies.

I got a couple very good condition alpine type S 6x9's sitting in my room at home, in boxes, work great,
