I need advice

I own a white 2002 Toyota Tacoma Prerunner Xtra cab. I want to put speakers, amplifiers, mids, subs, or whatever it takes to make it beat but i'm not really sure of what to buy. i need some advice on what is going to fit my truck also. Just whatever i'm gonna need to make it hit hard, tell me what that is and maybe make a reccomendation on a good product. Thanks
