I can tell you MBUSA lied to you just as they lied to me. I complained a multitude of times about the audio in my S550 Cabriolet. That car was recently in an accident and I replaced with S560 Cabriolet. In both models the audio was unacceptable to my ears. The NAV-TV product is the best way to fix it. It eliminates factory amp where specialized processing occurs. With the NAV-TV piece I have a clean, flat signal from head unit which feeds aftermarket equipment.
Other problems with stock audio system is the speakers. The door mid-woofers rattle internally at certain frequencies between 160Hz to 800Hz. Also tweeter drops off high frequencies around 12000hz as volume is increased. Solution was replace door speakers.
The front firewall subs are excellent and do not need to be changed. But additional bass is required. I added a sub in the truck floor with very little negative affect on truck space.
Remaining speakers have same tweeter frequency drop and mid-woofer rattles. But these weren’t important enough for me to replace since all are used for filler audio. The main audio is in the doors, subs, and center. The stock center channel is good enough to keep in place as well.

SO... Rather than take up trunk or interior space, spending $$$ on so much custom fab, here's what I did:
4 Dayton "Pucks" under each front seat and added 2 in the lumbar region of the seat backs.
Boss Audio 400 Watt amp drives all 12 pucks.
Remote volume knob attenuates the trunk-mounted amp.
The result is quite astounding!! You'd swear there were (2) 12" subs in floor of the car somewhere. Those little "pucks" kick ***! Literally!!

Here are photos of the installation of audio wiring in the truck and starting building the subwoofer enclosure. The battery is hidden under a metal enclosure behind back seat. The stock Burmeister amplifier is in the trunk on the left side hidden behind pumps for the convertible top.
Let me know if people here want me to post photos as I build out the install.
