Hi - I am working on an art project that incorporates sound. I would like to place two speakers in the frame of a doorway. The speakers would be running off of a DVD player (there's a video component in the art). My first question is - what kind of very small speakers would be best to use that are compatible with a DVD output? I would like to set them right into the door frame- so that the front of the speaker is flush with the frame. I have thought about car speakers but question compatability with a DVD player (the frame is only 6 inches wide). My second question: I hope to have a switch set into the door frame (like the light in a refrigerator - that goes on when you open the door) I would like to have the sound come on when the door is open and no sound when the door is closed. The TV and DVD will be continuously playing - but I want the sound to be intermittent. Can you advise the best way to do this? I've done a bit of wiring on projects but would really appreciate advice on the easiest and best way to do this-thanks-sandra
