Well i have a 1998 Chevy Blazer and i really want to add a new audio system in the car because most of the speakers are blown out and the radio is very outdated. Well anyways, i really want a good system that doesn't sound muddy, isn't the loudest thing on the street, but i can hear the music (highs and lows and some tremble) clearly, perfect amount of bass, and Affordable ($600 and below). So what kind of speakers, subs (Specifically Watts), equalizers, amps, aftermarket stereo, and cables would i need to buy and of which brand?

P.s. Im a noob with this kind of stuff and i know a bunch of people on here in the car discussion are experts with this kind of stuff. Ive also looked on other websites and can't find the info im looking for.
