Factory sub makes my head rest/rear deck area rattle like crazy and its super loud like i have 2 12'' subs or something. Is anyone else having this problem!? I just bought my first TL and 3 weeks ago its a 06 and i love it!! At first i thought my sub was blown, but i finally figured out it was just the deck behind the head rest. Is that something that Acura will fix under a warrenty (i dont think i even have one since im second owner and the is 76,000 miles) or a TSB? thanks for the help!
