This circuit is an universal protection for audio amplifiers, that includes: 
- delays about 5 seconds switching speakers on when power supply is turned on. 
- switches speakers off immediately after power supply is turned off. 
- switches speakers off if end power amplifier gets out of order. 
Power supply could be in the range 12 to 20 Volts. 
Overall dimensions PCB 46х29 mm. 

This kit is disassembled, requires assembly and soldering.
