AM/FM radio and wire identification

Both green and black wires go to the speaker? Car only has one central dash speaker.
There is a tiny Pentastar under the "15" between 102 and 108 FM:)


Damm! totally missed that! Good eyes!!

Speaker has two terminals I beleive.




Yeah I figure sound wont be great, id just like to hear something while I cruise :)



Do you have a model number? I was googling "Motorola PD2509" since that was on the label underneath.


Also, I noticed when the AM decided to work occasionally, there was interference with the engine speed. I know there's noise supressors built into the car, who knows after 50 years if theyr'e intact. Would my radio guy be able to install a noise surpressor into the internals of the radio itself? He's already going to add an aux cable wire I can route under the dash. Is internal noise surpression even a thing?
