12 volt TV converter box?
Anyone here running a TV converter box (digital to analog signal) directly off 12 volts DC?
My idea is to install a TV converter box and run it directly off 12 volts in order to tap into just the audio side and listen to TV over a radio speaker. I have a 7" digital TV but you can't turn off the display in order to save battery power. Often I only want to listen to the sound and not have the picture on.
If you have or know of a TV converter box that runs off 12 volts could you please tell me what the brand and model is?
