To install a stereo in a Dodge Caliber, start by disconnecting the negative battery terminal for safety. Remove the trim panel around the factory stereo using a trim tool, then unscrew and slide out the existing stereo unit. Connect the new stereo's wiring harness to the vehicle's harness, ensuring compatibility with a wiring adapter if needed, and secure the unit in place. Finally, reattach the trim panel and reconnect the battery before testing the new stereo.
