does anyone know the specs on the stock stereo sys that comes with the car.. do u think it has rca preouts or anything like that..and where can i find instructions on taking out the radio.. my friends owns one..and wants to upgrade the sound sys.. an amp and a small sub should do the trick for now...but i don't know whats behind the deck. its a 2003 accord where the deck and a/c controls are all built in one...it does not have the nav sys.
