Metra 72-5602 is a speaker connector designed for 2010 and up Ford/Mazda vehicles. It allows you to connect aftermarket speakers to the factory speaker wiring without cutting or splicing any wires. The connector includes four wires: solid white, white/black, new speaker (+), and new speaker (-). If you intend to retain the factory tweeter, connect the solid white wires together and to the positive terminal of the replacement speaker. Connect the white/black wires together and to the negative terminal of the replacement speaker.
