If you're looking to hook up a good system, don't go to Best bUys or circuit city or any of these large chains. They'll stick you with shit you don't need. I would go to the small audio chains and they'll bargain with you. Be smart though. You need to know what is it exactly you're looking for and do some research on audio systems. Now if you just need a stereo and speakers, its ok to go to these large stores. What kind of system and how much cash do you want to spend and what kind of car do you have?
