Is it possible to wire a PIR to a traditional stereo CD player/music centre?

The actual CD player or music player doesn't have any connections for a PIR, and if you powered it through a PIR then it would only turn on each time and then you would have to press play manually. What you could do however is use the PIR to switch on powered speakers, and have the music playing all the time on the cd player (on loop for example) and then only when the powered speakers come on do you hear the music. You could do this by wiring a plug and socket arrangement to the PIR so that the PIR is plugged in to the wall socket and then when it detects motion it switches power on to the outgoing socket coming from the PIR. Hope that makes sense.

Hi you could also do the same thing with normal unpowered speakers if you get yourself a relay with 230v coil circuit you could then wire the speakers through the relay switching terminals & have a pir energise the coil & thus make the connection to your speakers but likewise you would have to keep the cd running on a loop all the time.
