To uninstall the radio, one has to first remove the cable connected to the negative terminal of the car battery. For the models from 2000 to 2005, remove the glove box, and unplug the heater control cables that are placed underneath the glove box. Then, it is necessary to take out the center trim panel and, possibly, the radio mounting screws/bolts. Pull the radio out, reach behind it to remove the electrical connectors and the antenna lead and installation is the reverse of the removal process. For the door speakers, first, you have to disassemble the trim panel of the door, then have to take out the screws that are attached to the mounting of the speaker, to pull out the speaker and eventually, you have to disconnect the electrical connection of the speaker.
