How do you remove non-Bose rear speakers from a 1997 Nissan Maxima?

I have had to remove the lower section and upper section of the back seat to start this process. To do this slide your hand along the bottom edge of the lower seat until you feel a ring, now pull this towards the front of the car (Remove lower section of seat from car now). Next there is a screw on both bottom sides of the upper seat section that connects the seat to the car, Remove these two screws. Now I found two more screws inside the panel that folds down in the middle of the upper section of seat. Lower the panel and pull the fabric retainer up and away from the trunk wall. These two screws were in the car at a ridiculous tightness, I literally had to get my biggest screw driver to turn these out. Once these screws are out then the seat is free and remove from car. Now the reason these need to be removed is because Nissan mounted the speaker grills right to the rear window deck. In order to remove this you need to remove the seats, and now the side panels that sit next to the rear window and hold down the rear window deck. These come off fairly easy, Just start at a corner and wiggle and pull until each bracket seperates from the car. Now the rear window brake light needs to be removed in order to remove the rear window deck. This I have not figured out yet how to remove without just breaking it off out of frustration (hence the reason I'm on the net looking for answers.)

To complete the removal of the rear deck to access the speakers below, you need to crawl into your trunk with some pliers and a flashlight. If you look up to where the speakers are you should see a couple of white retaining clips. If you squeeze the exposed end with the pliers (careful not to break clips) and push up on the deck simultaneously you should be good to finish your project. Thanks a lot Nissan for making that so flippin complicated.

The center brake light mount is actually removed by turning the whole assembly counter-clockwise about 1/8 of a turn.

Try to use the Nissan speaker adapters plugs so you don't need to cut wires and mess up the electric system, you can get those from eBay or amazon.
