To disconnect the negative battery cable, remove the dash panel surrounding the radio. If necessary, remove the air conditioning control panel and front console trim to access the radio mounting screws. Remove the mounting bolts and pull the radio outward to access the backside, then disconnect the electrical connectors and antenna lead. For the Car Speakers, remove the door trim panel and disconnect the electrical connector. Remove the speaker mounting screws and remove the speaker from the vehicle. For tweeters, remove the door trim panels or package tray to access the screws mounting the tweeters. Disconnect the electrical connector and remove the tweeter. On Sciara models, pry up the speaker grilles and unbolt the tweeters. Installation is the reverse of removal.
