Introdução
There was no output from the Right speaker RCA output jack, so I disassembled this to try to diagnose the problem.
Confusingly, the Right audio output jacks is located to the left of the Left audio output jack.

Turn the subwoofer so that you can see the front metal panel of the plate amp. Using a #2 Phillips screwdriver, remove the 8 screws on the perimeter of the plate amp.

-
CAREFULLY and gently pull the plate amp towards you until you remove it from the enclosure. Do this gently and slowly, so as not to tear/stress the red and black speaker cable going from the subwoofer driver to the plate amp (in middle of photo).

Two pairs of (diodes?) near power connector. This is probably a full-wave rectifier bridge to convert the 12V AC from the transformer output to DC.
