[spoochmlb52]

Hey guys im still in highschool and this is my 2nd car, i first had a pontiac but thats dead, now i have just got a 1993 Lexus es300 and im very pleased with the car.... I already installed my deck and sirius sattelite today. Now i need to replace all the speakers. I need to know how to remove the rear shelve speakers and all the other ones with out breaking anything. I dont wanna mess anything up. I have some extra sony xplod speakers form my old car that i wanna throw in the back, there 6x9, i belive theyll fit but how do i access removing the rear speakers. Also what size are the speakers in the dash, thanks!
