Ok...let the flamefest begin...

I have never done anything when it comes to audio in the car...but I just recently purchased a stealth box for my del sol...I know how to "put it in", but dont know how to "hook it up" (the amp, wires, CD Player..) is there a place online that will show me how to do this IN DETAIL, or should I just pay someone to do it? What type of amp should I get?
