replacing factory speakers in my '99 GT Options

[runriot95]

I just recently got my '99 celica and I'm already itchin' to replace the sound system. My question is on how to remove the old speakers. The door speakers have 4 slots that look like you just slide a screwdriver in them and pry the grills off but when I do that it feels like I'm gonna snap the plastic grills. Any suggestions on how to remove these?

The rear speakers- I got the grills off but then I learned you have to remove the side panels as well. I removed all visible screws on the panel and pryed the trim panel away from the door jam but it seems like something is still keeping the panel on. Do I have to remove the rear seats to get at another screw?

Also, are there any tricks to removing the head unit that I should know about or is it just simply a matter of prying up the trim?

Any and all help will be greatly appreciated. Thanks!

The front door speakers can only be accessed by removing
the whole inner door trim, this will mean removing several
screws along the underside of the door, removal of screws from the door pull cover and 2 screws covered by 2 round
black plastic caps (looks like a large chocolate button.)
Oh yeah there are two plastic clip fasteners near the
outer edge of the door.These look like little round plugs.To
pull these out you must press the centre part in until it clicks.
Also one screw in the armrest.Remove triangular plastic cover off the door mirror base.You can now lift up the
whole door trim upwards by the armrest.Behind it you'll
find access to the speaker which is "moulded in".The rear
speaker is a lot more involved since it requires removal of
rear side panels, one bolt by the speaker and one bolt holding the trim behind the rear seat. The rear speaker should come out attatched to a triangular frame.This is
moulded into place too.I'll stop here cos my fingers are gettin numb.. The head unit trim can be removed by first
pulling the panel around the gearstick gator, here you'll
find 2 screws holding the centre trim in.Once removed just
ease the plastic trim off nice and easy..
