3rd Row Driver Side Speaker Rattle

[Tellthemride]

After almost 5 years of owning my 2020 SX, my left rear speaker sounds like it's either loose or starting to go. If I have the bass turned on default setting, and play any dance/pop music over the radio that has a low frequency bass beat, the speaker gives off a rattling noise. At higher volumes, not really noticeable since the music drowns out the rattle noise, but at lower volumes, it is noticeable. Will check with the dealer at my 5 year service interval soon. Wondering if anybody else has dealt with this yet? The audio warranty was only good for 3 years of course.

Reading from other sources that the root cause could possibly be from a loose speaker grille or fastener.

Turned out to be the subwoofer in the left side of the trunk. Took my dealer about a week to special order the replacement sub. Only took about an hour to replace when installed. It was covered under warranty repair, which is surprising since my Audio/Entertainment warranty expired in 2023. Not going to complain about free.
