I need some opinions on what is a good 6x9 I want a little extra sound in my car without adding subs so any advice???

 

youre not gonna get a magic result by just changing speakers. the quality will increase but you will never magicly have an amazing system with one single upgrade. that said.

alpine, pioneer, helix, DLS, hybrid audio, massive audio, kicker, rockford fosgate, image dynamics. these are some of the most reliable brands.

They have some pretty good prices. My buddy has bought a few things from them. with good results.
