Step 1: Performance Verification Certificate (PVC)

Start by locating the Performance Verification Certificate (PVC) supplied with your Rockford Fosgate amplifier. We'll use data from the PVC to determine how much current your amplifier will draw from the vehicle's charging system.

Performance Verification Certificate
A PVC confirms your Rockford Fosgate amp was tested using state of the art equipment and meets or exceeds rated specifications.
