Hi all,

Recently I been hearing some sort of clicking sound coming from the back, I'm not sure what it is. It sounded like some one using a pin and tap onto the metal or plastic. Any ideas where it would be, I would like to just fix this one my self. Thanks.

 

I might have the same noise as you. I had been searching for that noise for weeks and I think I finally found it.
I believe the noise is from the back of the panel where it holds the bass. I opened up the trunk and tapped the cover from inside the trunk where the bass is located and heard the same noise during driving and when the music is on.
I haven't had the time to remove the cover to check what causes the noise, but maybe you can try it or hopefully I'll have a chance to do it during this holiday....
