2 Miller and Kreisel subwoofer internals sent in for repair. This time it is (2) VX-7 systems. I did replace all of the electrolytic capacitors (except the main filter caps), Resolder and retension the Molex connector, cleaned the bass level, and crossover frequency pots too. It turned out very well.
