Connecting soft circuit sensors to a sound system?

I want to make a sensor that will cause a sound system to emit music. There are some 'ibles for making soft-circuit sensors, but I want to make it so that a speaker produces sounds when an object triggers a sensor. When somebody stands on this sensor, sound will come from a speaker. I don't have any experience with electronics but I can learn. Sorry if my explanation is repetitive.

I assume I have to get one of the Bluetooth Audio receiver boards like this . I think I should be able to find a 5volt connection somewhere in the Sonos speaker to power this unit and then have to hook it up to the AUX connection in parallel to get the audio going.  I was wondering if someone knows of a good bluetooth audio adapter that can pair multiple devices.  Also any other ideas or suggestions would be appreciated.  Thanks

Car Audio Kludge

I recently bought a used car. It has a radio, but no faceplate. While I could probably find a replacement faceplate or even install a new radio myself. I want to see if I might be able to DIY my own stereo out of the bits of my radio I do have and maybe an MP3 player or something. I figure the amplifier and power systems are all hanging out in the box there. So all thats actually missing is the part that acutally makes the audio to send to the amp. Anyone out there know enough about car stereo to confirm/deny my thoughts on this and maybe provide some advice?

How do I fix this without running two individual mono channels? Thanks in advance!

I guess he put in a full sized ear jack and it takes mini so it is obliterated. I got rid of the physical jack and all its parts but it still outputs audio to the dead jack apart from the "turn the fone on"  sounds. So, am I missing something? Is there some secret thing that is stuck in the on position? Anyway, probably lots of kids have broken earjacks so maybe someone has the same problem and knows a fix?
