I have a Rockford Fosgate power 600.4 that has suddenly started playing crackly high frequencies. I don't know how else to describe it, maybe kind of like clipping. I checked that it was not the head unit by changing input sources. It has been running in a bridged configuration for a couple years now. Because it has been running fine for a while, this was easy to tell when it ocurred.
I would like to try and debug this myself for fun so am hoping yall can point to a good place to start. I also work with a bunch of electrical engineers and have access to a number of debug tools if that helps. But I'm a mechanical engineer so my knowledge on this is relatively low.
Thanks for the help!
