Speakers
I used this speaker for the front 4x10 in my 67 dart. I have no speakers in the rear yet. Front one does what I need it too. I can hear it very well and sounds good. I had my factory 67 dart radio converted to am/fm with auxiliary hookup and 45 watts x 4 output with modern electronics, by randb conversions in Tennessee. I bought the speaker from him also. Jegs link was just easier to find and has plenty of info. Notice that on the bottom side of the speaker both left and right front wires will be connected to speaker.
