Loud Rattling when Music is barely playing.

[Chris559]

Hello Im new to this forum and have been searching all around the internet for a solution to my problem with no success. I have a 2011 Focus with the premium sound option so I have a stock 8inch sub in my truck and every time I barely turn up my volume I hear a loud rattling coming from the back. I have come to the conclusion that the sound is coming from the driver's side rear seat belt assembly and was wondering if any one could give me some directions on how to disassemble that assembly so I can see if there is anything loose in there. I really would like to avoid disabling the sub if I can avoid it. I appreciate everyones help and Thank you in advance.

There is no disassembly of those parts. You can remove and replace, but not disassemble. To get the plastic trim off will probably take a lot of removal. I'd double check all of the screws first to see if anything is loose or missing.

my 07 had an odd rattle back there- turned out one of the speakers only had two screws holding it down and one had backed out

Id check the 2008-2011 specific section and/or search, im sure someone has pulled those panels apart

Always tighten up the door panel screws first and check to make sure they aren't lose. 90% of the time for me this fixes it. When it doesn't, I'd make sure the speaker is mounted well by pulling the panel and tightening up on it, and maybe putting some Dynamat in. I had a rattle in my 2011's sub, but after checking out the mount it went away.
