I bought a couple new speakers to install in the dash of my Astro van. I removed one of the old AC Delco speakers, but I do not know how to connect my new speaker to the plug in (runs the wires to the radio). On my new speakers, I simply have a + and - wire, but I need to plug this into the jack that the old speaker was connected to. Do I need to buy this connector for my new speakers? Anyone ever changed their speakers in an old Astro Van?

clip the connector and strip the wires. use wire nuts or electrical tape to secure them
