What to do if my Rockford Fosgate 1000 Amplifier does not turn on?
- JJill FieldsJul 26, 2025
If your Rockford Fosgate Amplifier isn't turning on (and the power LED is off), here's what to check: * First, ensure the voltage at the REM terminal is between 10.5 and 15.5 volts. If it's not, inspect the alternator, battery, fuse, and wiring, repairing as needed. If the voltage exceeds 15.5 volts, have your electrical system checked by a certified car service center. * Next, verify the voltage at the B+ terminal is within the same range (10.5 to 15.5 volts). Again, check the alternator, battery, fuse, and wiring. Also, have the electrical system inspected if the voltage is too high. * Finally, confirm the amplifier is properly grounded, checking the wiring and repairing if necessary.
