ABSTRACT:
A multi-speaker system for use in automobiles includes a woofer, tweeter, and midrange speaker with the tweeter and midrange speaker being mechanically and electrically detachable from the woofer by removing an upper grille thereof. An external lead wire entering the rear of the woofer is branched at a location centrally of the woofer cone into a connection for litz wires for the woofer and a flexible lead wire connection for the remaining speakers to prevent inadvertant contact between the lead wires and car frame members.
