Today i was looking into upgrading my stero system which turned out to be a problem. I have only had the car for around 6 months its a 99 ss and the radio itself is an aftermarket sony. The guy at circut city told me i had 5x4 in the front and 6x9 in the far rear. So i went home and started looking.In the far rear were some wimpy ass like 4xnothins and the front were definatley not 5x4. But the clincher was the fact that the speakers in the back seat (which i was told didnt exist) were sitting there un hooked. Can some one please tell me if the speakers i have came like that or how i can fix it or somethin. Oh and the speakers are delco all the way around.
