WOW! What a royal PITA to replace these rear speakers.I have a '94 maxima, but i think the speaker replacement is the same for several generations of Maximas. Eliminating that useless rear speaker amp was easy.
So I pried on the speaker covers for about an hour with no success. It seemed so easy because inside the trunk you can see the speaker screwed down. Well those covers are molded into the rear panel. So I had to remove the lower back seat (just pull up hard on the lower seat to remove), to get at 2 lower bolts holding the upper back seat in the 2 low corners. Remove 2 lower corner bolts. Note that the hook on the lower seat mounts outside the screw hole, not inside. Then remove the armrest cover from inside the trunk (2-4 phillips screws). Once the armrest cover is removed, there are 2 M6 (10mm socket) bolts holding the seat in (remove). THEN, if you lay in the trunk and look up, there are 3 alignment spots on the upper seat that fit through holes cut for them, on the sheet metal. I squeezed the male alignment things, then pushed up to release the seat back. Now the rear seatback is out.
I released the green tabs from underneath (inside the trunk), then I pried up on the rear cover to expose the speakers. I only got the cover up, not off. I removed the front speaker screws with a stubby phillips. The rear screws I had to use a right-angle screwdriver. Painful and slow. Then I used the screws that came with speaker and the sheetmetal clips over the factory screw holes. They are smaller, so they thread in by hand quite easily, and only need some tightening. I ran new speaker wire, to eliminate that dumas, useless "static-amp". Solder and shrink tub your connections and suddenly your stereo is awoken!
Have fun!
