I don't have any better pics, this was taken when I installed my nice new Memphis 6x9s. But you will need a 15mm socket and wrench, pop out the bottom seat and remove, unbolt the 4 bolts for the seat belts, slide rear seat up and out, 4 hanger hold it on so you have to lift and pull out. After the deck is held in by 2 big plastic retainers on each side iirc, then it just pops up and slides out over the speakers, then you see what I have pictured above... after that, you're on your own.
