I haven't posted on this in a while. I opened the amp up and took some pictures. It definitely looks like its been under water, but nothing stood out to me as an obvious short. I cleaned it up with alcohol and re-installed it, but still no sound. Does anyone know how I could go about troubleshooting if the amplifier is actually toast?
I have some aftermarket amps that i would rather install over replacing this thing, but someone told me most of the aftermarket digital converters require the factory amp to still work. not sure if that is true.
