Ok.. driving home tonight the alternator/battery light came on. At an idle I can feel the car feels rough.. Its definitely not idling right.. Should I assume the alternator went out? Should I even drive it to the dealer? Still under extended warranty at 89990..

Anyone have this problem? Figure I should take my amp and speakers out so the dealer doesn't try to screw me..

I love my car.. but she is a ***** sometimes.. fifth trip to the shop in three months..
