What to do if Rockford Fosgate Amplifier does not turn on?
- JJanet CervantesJul 26, 2025
If your Rockford Fosgate Amplifier doesn't turn on, verify that the voltage to the B+ terminal is between 10.5 and 15.5 volts. If it isn't, check the alternator, battery, fuse, and wiring, and repair as necessary. If the voltage is above 15.5 volts, have the electrical system inspected by an authorized car service center. Also, make sure the amplifier is properly grounded by checking the wiring and repairing it if needed.
