Alright, no pics but I can tell you how.
Unfortunately for our civics you can't get the to speakers from the trunk so you have to take off both rear panels under the small rear side windows. You might need to take off the bottom plastic that runs along the bottom of the door sil to get the side panels off. You also need to bring down the seats becuase behind them is a hidden screw type plastic thing that you must pop out, *DO NOT LOSE THIS* Look at it from the side and you will notice that you must pull the side plastic straight out to pop it out without breaking it. Once you do the same thing to both sides your able to take out the rear deck. The rear deck is much like your door panels, it pops off so gently pick up the plastic, make sure to slide the seat belts through the slit located at the bottom on the whole they are located in the rear deck, your whole rear deck while come out in one piece. Once its off your able to get to the rear 6x9's. Just go backward to put everything back together, make sure everything is snug and tight becuase if you have subs that rear deck will vibrate and cause alot of distortion during loud bass sessions if the deck isn't properly secure. Good luck, this was like a crash course in taking off your rear deck, if you run into any problems or got any questions PM me and I will help you out.
