installing rear speakers (93)

how the frick do i get off the casing? do i need to take off the blue velvety stuff? p.s. im 15, will have my permit on October 26th, and am just fixing up my FIRST car so im not great on terminology.

I have a 92 and am thinking about buying new speakers for the whole car but i am debating this since to access the front speakers i have to take off the door panel. If you have already done this do you have any tips or if you haven't gotten to them yet, just a warning.

I suggest you get a Haynes manual at a local parts store and read the appropriate sections for the speaker replacements. For the rear you need to remove the entire back seat to get the panel off. For the front, removal of the door panel is not too difficult, there is an inexpensive special tool that helps with the clip removal. You will need to disconnect any power cables from the door switches (windows, mirrors and perhaps locks).
