The external speaker plugs into a box that comes with the radio. When installed, the box is hidden. The radio plugs into the box along with the antenna wire and external speaker. There must be a control board inside the box to control all the signals. </div></BLOCKQUOTE>
I have a black box behind the dash that the antenna hooks into. I'll check to see if it has a connection for a speaker jack. Thanks.
