rh9cg, i recently ordered some stuff from crutchfield, and they gave me master sheets for the bonneville, and one shows how to remove the door panel, it'* a little off on some parts, but it gives a good picture on what needs to come off

i scanned the page, if you would like a copy just pm me your email address and i can send it to you

the tweets are 1.5 and the speakers are 51/4 the door is a pain to get off without damaging clips take your time on your first try just to salvage as many as you can without ruining the teeth on em, there is a screw behind the light and on mine there is 1 under the arm rest and be careful of your lock switch if you have power locks i cracked one of mine and had to buy a new one hehe

oh and i almost forgot the stock speaker harness wont work with any after market speakers i clipped mine with about an inch of wire left on the backs of them just in case i ever wanted to put the stockers back in for resale, but i would definatly solder the wires to the speakers because it gives them much better sound quality. and they wont fall off if you drive like me
