TSXautoXer

I am a audio engineer and I have been trying to find out the cause of rattling in our beloved TSX. So far, I am pretty sure that volume has less to do with it, but as to certain frequency. I wanted to conduct a test to prove this. The problem is I could not plug my noise generator into the audio unit (they didn't teach us car audio/electronics). Anyways, guys, if you know the full detail of how to access to the auxilary input of the head unit, please let me know. Then we can really tell acura "Hey, it's not us to play our music too loud!!".
