Audio Systems: REAR SPEAKERS, rear speakers, zise

Question
I NEED TO REPLACE THE ORGINAL REAR SPEAKERS ON A 97 CAVALIER. THE FRONT SPEAKERS WORK FINE, BUT I HAVE NOTHING COMING FROM THE REAR. I USED A TESTER AND I HAVE POWER TO THEM, BUT NO SOUND. HOW DO I GET TO THEM TO REPLACE THEM.

THANK YOU VERY MUCH

Answer
you have to remove the rear deck to get to them
but first check the small factory amplifier some cavaiers not all of them have a 2 channel small amplifier the zise of a cigarret pack this unit is in the trunk  left side  the box is gray and blue or black and blue

because 2 speakers don't go bad at the same time
