Okay, So I finally got these finished.
Here is a picture of the 2 speakers, the one on the bottom shows how the layers come apart.
First thing I did was pop the RCA logos off
Here are the 2 emlems side by side. The RCA one has 2 legs and the polk only has 1.
I drilled a hole in the center of the 2 and the polk logo fits fine. (sorry about the blur)
Behold the awesome 3 watt RCA speakers (that don't work)
Next to the polks (I found out later that the screw holes didn't quite line up, but the self tapping screws went in just fine.
