What model pioneer speakers will be the best bang for my buck? I remember reading that once you get past a certain point you cant tell the difference in quality of sound if you pay more. My 04 civic has 6.5" in front and 6x9 in back. I know nothing about the specifics of speakers which is why I'm asking. I have an amp and subs (2 12" pioneers) but I would rather have awesome sounding music that I can crank up rather than ear crushing bass. So looking to sell the subs and replace with speakers.
