My car has just started to make a funny light rattling noise at certain sound levels / bass levels.
Even though it is onliy a slight rattle it really is annoying.
I have upgraded the the door speakers and have a sub and amp.
If i have bass set to any more then +1 then there is a funny vibrating noise comes from around the headunit area.
If i press on the head unit while it's vibrating it nearly stops so it could be the heater vents also.
How do i tighten up the HU?
Has anyone else had this problem?
