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!

i gutted the entire interior to install my system. but then again i went all out. i ran 2gauge power wire and the best rca's i could find. i ran a sony head unit 6.5 mb quart seperates in the front and rear 2 12" jl audio subs in a sealed inclosure and only 525 watts and hit 146 db. i actually cracked the windshield. then some litle punk decided they were to lazy to get a job and buy there own system and helped their self to mine. i lost over 3500 in equipment. so now i keep it very small and simple. but the celica is a very acustic car and even small systems can sond great in them
