Don't know if this is the right subforum.
I found this old amp. But I don't know if and how it works. Can anyone help me?

Thats an old car audio amp, from the early-80s... IIRC those usually were under-dash / seat installed.
 
~14.4V DC, and you'll need a compatible DIN plug and block connector.

Thank you. Do you know where I could get adapters for this?

I've been out of car audio since the early 1990s.  I would start by searching the car audio forums for pioneer DIN plug and block connector sources. That amps is 30+ years old and seriously rusted out and in need of some DIY repair.  Bent corroded pins generally don't work very well if at all
 
Heres the pin out for that amp:

Good Luck!!
