I'm not sure if its from the bass or what. But I'm about to order another i found on eBay. But I don't want this to happen again on new one. Did anyone have this issue with the unit?... I even put nice seals around trunk and other places, so not many rattling issues.. Sounds good! 2x 12's Kicker!

 

look in the special area for audio,,better luck finding prob and gurus there

Note air movement= speaker operation
sealed area doesnt produce the best sound
open sunroof and hear!

iirc there is a ground under the spare tire- often removed when old sub is removed or unplugged?

if you buy another nav be sure the security code and cars vin it came out of are included
each unit has its own code
there are several great options on new radio with nav aftermarket--see diy and audio sections for more info
cheaper than updating the nav disc~

 

Meh ditch all that and get a Double Din DVD+NAV... Way better than any OEM Option.
