I have a 2002 Saturn SL2 and the back speakers are 6 1/2". I don't know how to take the front door panels off so i don't know about the front. I believe both the front and rear speakers are 6 1/2"
ford falcon au's take 5x7 speakers front and back
In trunk the felt below the speakers is removable by a couple of friction buttons. Take them out and then unscrew the speakers and disconnect the wires.
Just take out the speakers from the speaker box and make a new box for the speakers if they dont fit.
They can take 5 1/4 inch speakers. 4 x 6 speakers fit too.
size is 12/150
the rear seat back will probably have to come out and then you have to take the rear package tray out to get to the bolts holding the speakers in.
Take off the inside door panel and see what might be in the way when the new speakers are installed.
rear 6"X9" and the front is 6.5"
