personally, I would get some extra $$$ and change the speakers while you got the door panels off as they are a b1tch. try some 6" splits for the front and some good 6x9's in the back. dont rely on the rears for good bass tho. I tired, it failed the toyota wiring is ........ wel fun to understand. I used the power the pwr from the old stereo, but all the speakers stuff is all new cable. the front panel where the stereo is, is just a clip-in. There are 4 bolts that hold the stereo and the tray under the stereo in. undo them and TADA!, the stereo is out hope this helps, FYI, if you in my area, I can help :D
