Yu thank a bunch bro. Since you have it set up for woofers on yours and you have same stereo, next time im in town i will hit you up and check out your set up and try to copy wiring... As for the OBD2 i installed it in my A4 and it did not do anything because i passed my inspection and they were able to read my OBD2... I dont know i just dont like Bose that much plus my drivers side front speaker is rattling which is very annoying lol
