I have a Fosgate Type RF X 4 that I bought in none working condition. It had 2 blown power fets. I replaced those along with the drivers and gate resistors. The amp now powers on and functions well. The only problem I am having is the fan. There is no voltage to the fan plug. What should be driving the fan and where should I be looking for it at? Also, someone has made modifications to the amp previously. I am not sure what their purpose is and whether I should return it to how it came from the factory. See photos.
I've never seen an x4 but the mods you show are factory.
The fans are typically thermally controlled in Rockford amps. Try heating one of the thermistors to see if the fan will start.
Rockford may send you the diagram for the amp if you email them.
