My 2011 SRT 392 I.E. just bought 9800 miles HAS the Trunk monkey thump . it also does it inside car from left front speaker(it seems)
I am taking it in to dealer for 2 recalls---door handles and smart switch on windows----also trunk latch sometimes doesn't work with touch.
The service manager was fully aware on the 2 recalls and said they will fix no problem-o
but kinda played dumb about the "Noise"

MY QUESTION is does anyone know how to get the TSB for this (believe there is one about reflashing the subwoofer and eq) so I can show it to the dealer? or what else should I try? Thanks, I LOVE this car but afraid I will have to explain the noise all the time.

There is an update. I had mine done and it made it sound so much better. Still hear a slight thump when I open the trunk but so much better. Sound improvement was very noticeable and I don't have good ears.

The TSB#08-087-13 or #08-035-13 should be what you are looking for.
Believe the 1st more for 2013.

Attached a couple of files depends on year,model and radio types.

If they hook up your vehicle to WiTech it will show any flashes available for your particular radios.
Other updates are done via update discs.
