R11 6X9 speaker

[BZaar]

Thanks to everyone for all the great responses / pics and CORRECT information.  I now know way more than I did when I posted originally.  I will also add that my broadcast sheet does clearly show the R11 + R31 on line 10, which as we all know now gets you the AM radio (R11) with (1) 6x9 rear speaker on the drivers side (R31) + plus rear speaker fader knob on the dash.
