After replacing the stock Concerjunk with the Pioneer multimedia unit I realized how bad the stock speakers actually were. (Only inside speaker had failed completely)
Since the space they had occupied under the cabinet was so tight, I had to fabricate a couple spacers to allow for room for the deeper Pioneer units.
Everything now sounds like it should, so much better quality it is hard to believe. (I still have to put little white caps over the screw heads)
Next step will be replacing the extrior speakers.
