  If your Rockford Fosgate Car Receiver doesn't turn on, it could be due to a few reasons. First, the voltage applied to the red and yellow wires might not be between 10.8 and 16 volts, or there might be no voltage at all. Check the battery, connections, and fuses, and repair or replace them as needed. If the voltage is above +16 volts, have the electrical system inspected by a certified car service center. Another potential cause is that the source unit isn't properly grounded, so inspect the wiring and repair it if necessary.

  Speakers popping when turning your Rockford Fosgate Car Receiver on or off can be caused by a couple of issues. It might be that the auto antenna and remote B+ aren't configured correctly, so check the wiring and repair as necessary. Another cause could be a bad component in the signal chain. To find out, check connections and bypass all components between the source unit and the amplifier. Connect one component at a time to determine the culprit. Connect this component to the Blue wire and check for pops. If pops persist, repair or replace component as necessary.
