[paintballinu12]

I am looking into buying a good system for my car. I love listening to loud rap music, and i want a system that can put out some serious sound. However i don't know much about car audio. It will be going into a 1999 Ford Explorer. I don't want to get ripped off and theres only so much im willing to spend, about a thousand dollars. So give me your feedback on what i should buy. I know i want some subs and new speakers, but i need help. So gimme ideas.
