Speaker replacement in a Maxima

Looking for help on speaker replacement in a 1998 Nissan Maxima.  Not sure how to remove door panels, and rear covers in the back seat window.  Any help would be appreciated!!

not sure how much ill be, but ill share what i know. if you have manual windows, you'll need a special tool or a putty knife to slide the clip off the crank. depending on how the panel is made, look for any screw that may be holding the panel on. once you have all the screws out, you should only have plastic fender plugs holding the panel on.  about the rear deck, you may have better luck going from inside the trunk. if the car has raised, grill style covers, then you may be able to use a flat head screwdriver or an upholstery tool to pop the cover off.  email me at marquisz28@yahoo.com and let me know how it goes or if you need more help.
