PLS HELP: 2013 ML350 BLUETEC, SUB FUSE?

Hello everyone

My sub suddenly stopped working on my 2013 ML350 Bluetec with Harmon Kardon package.

Checked the fuse map provided with the vehicle and unlike the older models there is no specific listing for amp/sub independent fuse.

A radio fuse was found at the panel located right rear under seat, but only listed as radio which the rest of the system is fine just no sub function.

Any suggestions or past experience? Could it be a full sub replacement required that's located in the left rear quarter panel?

Thank you

Unfortunately no.

There's no specific fuse for Sub or Amp like the older years of ML where is located at the right rear trunk interior panel.

The right rear under the seat fuse box contain a list of fuse and its location. But still none listed specifically for the Sub or Amp.

The radio its self still remain working and all other speakers.

I had similar issues happened to me few days ago, it was like super cold -30 degree and i parked the vehicle outside for overnight. Although i have the vehicle plugged in, but when i started, there were no sub sounds coming form the speaker. The only thing i can think of is my battery is weak and the system try to reserve the power and cut off the sub. I drove home(took me about an hr) and restarted my vehicle, the sound from the sub came back. So i wonder if it time for me to replace a new battery
