I used this solution to recover an old speaker that I would have otherwise thrown away. I bought this radio with Bluetooth receiver and USB / mSD player, an amplifier and a power supply on Amazon for a few euros and everything is great.
On the back I replaced the speaker connectors with a small panel housing a male Schuko connector and an on/off switch, both of which were salvaged from a non-functioning PC power supply. The dimensions of the holes on the panel are:
Hole for Schuko male socket: 27x19.20 mm
Hole for the switch; 19.80x12.80 mm
Hole provided on the acoustic box: 47 mm
Good print!
