Hi,
I recently purchased an A3 1.8T 2001 8L and have decided to swap the stock Concert II system for an Alpine unit, I removed the stock unit and purchased a PC9-401 harness which I think is incorrect maybe the PC9-404 as I have no BOSE speaker but a stock sub in the boot? however when I connected the Alpine unit using the 401 harness I have no power to the unit at all??? any advice appreciated.
Thanks
