I know you have to take out the seats to get the rear speakers out. But How do you take out the back seats? I have a 94 G20

Here is a link that has pics and instructions. Be careful with the headliner on the rear posts when removing the rear deck, I have one side that is all lumpy and bumpy now. http://www.carstereohelp.com/stereoremovalInfinitiG20RSpkR.htm
