2004 A4 Symphony no 12v switched?

Using the 70-1787 amplified harness on this car with the Symphony (no bose) and notice that the there is no 12v switched pin that corresponds with the one in the metra harness.  I just got this car, so I know nothing about it.  Is there a connection that I can tap into besides going to the ign harness for 12v switched for my aftermarket HU?Hit it again! It'll fit!

Check the cigarette lighter plug.  Otherwise, many German cars actually have a barrier strip under the dash where you can easily tie in.  Just test the wires and find the ignition lead there.My ex once told me I have a perfect face for radio.

Hooked it up, but it sounds terrible.  The rears, which hook up via RCA's on the metra harness are ~75% quieter than the fronts which are driven by speaker level from the HU.  Had to fade to RR9 just to even it out.  Did I miss an amp turn on?  I did make that connection on the harness.  There is absolutely no bass from the factory sub, or it is so quiet, I cannot hear it.  This sucks.  If I can't make it work as good as the factory radio, I'll just buy the stock Sirius Tuner.  I had an extra HU with a sirius tuner already, so I thought I would try it first.Hit it again! It'll fit!
