Hi i was wondering if anyone can help me with this issue that just arose. i just installed an appradio 3 and took out the old factory 6-disk unit. The issue i am running into is the with the wiring schematics that match my car are the ones for the 04 module and not the 03. After i hooked it up to test the sound quality from the speakers i found out every thing works minus the subwoofers in the back. i looked at the radio speaker thread in this forum, but like i said it seems like the wiring is different in my 03 than what was posted.
