One Speaker not working

[98GRDisco]

hello everyone, question about speakers in a Disco 1.

Ok the question is are all speakers working in yall's disco one with the integrated amp? I was trying to replace the radio and I noticed the rear driver side speaker does not work in my Disco 1 and i don't know if it ever did work.

Here is the weird thing though the rear 6.5" mids are working the fronts are working an the rear passenger side is working and from what little wire I can follow it is not cut or anything.

How many channels does the OEM amp have because I am thinking on of the channels are blown.
Let me know what yall think could be the problem please.

You could take out one of the speakers that work and exchange it in order to test it. I also had one that was out. I exchanged them both but I still have one spare. If you need one let me know.
