How do I add an Amp and replace all Speakers if I have a Symphony II
One head scratcher I forgot to mention is when you plug the panel harness back into the door controller. You have to pull back a latch to disconnect it in the first place. Well it has two locking notches. If you don't swing it all the way back when you push the connector back in, it catches the wrong set of tabs and doesn't connect. No door lights; no door switches. Make sure it's all the way back, push the connector in, and then swing the latch all the way, snapped closed. Push the door lock switch to wake up the controller. If you're hooked up right, you'll hear the lock cycling and see the door panel lights turn on.
Good luck!<ul><li><a href="https://forums.audiworld.com/audio/msgs/27508.phtml">My 2002 A4 speaker install</a></li></ul>



So it can be done.
