Can i add subwoofer in my 2 channel stereo amplifier using it ?

No. It is only for converting normal speaker line coming from stereo to RCA LINE

there are justr 4 wires for speaker input.how to connect to amp for signal?also this doesnt need power supply?

The 4 wires will connect to your original speaker wires! N you have to use a rca cable to connect the Amp. And No it doesn't need power supply.

can i convert from 10 watt to .25mWatt ,with this please clarify?

NOT Sure but it converts 12V to 2.5v
