Cerwin-Vega likely doesn't even have the schematic for the thing. They
likely bought a plate amp module from a Chinese contractor and integrated it.
Pull the thing, see who made the plate amp. You may find some people in
China have reverse-engineered it, and you may also be able to look up the
data sheet for the PWM IC on it and discover the whole thing right out of
the sample circuits.
