I know this is the wrong place for this but I know you could probly help more than anybody. The dvd player in my car has to be manualy turned off even after the ignition is off. Is there something I can Buy or Build that will act like the remote turn on of a amp, so that the dvd player turns on when the head unit turns on and shuts off when it does? If I have to build it where would I go for plans?
I'm not sure how I'd go about doing that one. If you have any sort of trigger signal, you can use relays for what you want to do easily enough, but without any sort of trigger, you pretty much need to just have a toggle switch for the amplifiers for the remote line, or just wire the remote trigger to the ignition line instead of a pwr antenna lead, and have the amp on when the keys are in the ignition.
