What's up everyone, I'm a pretty new owner of a 2014 E350. Just wondering if someone knew the size of the speaker and subwoofer on the rear deck lid. I hear a bit of rattling when the volume gets turn up, and I am pretty sure one of them could be blown. Thinking about upgrading, but unfortunately I need the size of the speaker before I can shop around.

It could be a mechanical issue with the speaker mounting, etc

Probably has it figured out by now.

I had a similar issue. I thought the speaker has blown. But turned out that it was a small piece of broken plastic trim (clip) from rear speaker grille cover (due to heat) that had fallen into the rear speaker vent which was causing resemblance of a blown speaker sound/rattling. I removed it using a tweezer. Problem solved.​​​​​​​
