I have a 2002 Jetta with a single din stock deck in it... i bought a wiring harness for my dual 7" flip out cd player... i start the car the cd player comes on and the system sounds really good, then i shut the car off, cd player stays on so i shut it of with the remote. Then i start the car again and cd player doesnt turn on. Then after a while the cap stays on like its running power from something and it kills the battery, so i have to pull the wires off so it doesnt kill the battery in the car. I was told that i need a harness that has a 12 volt shut off when u open the door but i have no clue what this thing is doing, anything will be helpful.. thanks
