Thanks for your interest. It comes from a used market and some electronic components are missing on the amplifier board, the rest works well.
The circuit is quite simple, a pair of LM3886 per channel in bridge with photoresistor limiter plus an NTC resistance that drives an LM317 to vary the speed of a cooling fan. I would not waste time getting the values of the missing electronic components, possibly I first put a different type of amplifier, there is enough space inside.
I don't think he's a re-branded Behringer because the LEM company belongs to the historical Italian companies. Unfortunately, today it no longer exists.

Nope, don't think so: Generalmusic - Wikipedia
Seem to be able to find the Lexus RX300 wiring diagram, but not this!
Thanks for your interest. The missing electronic components are due to unsuccessful repair attempts before buying them at the second-hand market. Here I have found some photographs of the complete electrical board, unfortunately they are not very clear and the value of the electronic components cannot be read.
