All right, today I went buy the local audio shop and got a quote on a sound system. Keep in mind i'm a newb. For 4 Infinity 6x8's ($190), 1 crossfire ur142 amp ($139), 1 Crossfire CF 12" ($85) a 12" box ($65), a new head unit ($200) and labor it would run about $800-$900. I'm asking for Christmas and can't get it all. Now, I know at least the front speakers are a must. But my parents wont spend $900 on a system for me (which is reasonable). WHICH ITEMS ARE MOST CRITICAL????
