Alright guys, and girls. I don't know jack about car audio, so I might as well look stupid, but atleast get some good info. Would a 200 watt amp give me any trouble on my alternator? It would be going to two 120watt 6x9's. And Yes I know they're small and probably a waste of money , but I got my Auto sentra I am going to get rid of when I'm 18, because then I can make my own life desisions because I am TO inept right now. So I am just trying to get some sound at a cheap price.
