Sound upgrade 2013 sig

[savage56]

Hello i have 2013 model s sig with hi~fy sound system.
I want to add aftermarket amplifier rated 370rms at 4ohm
1050rms at 1ohm
Rated fuse 80a
I have read different articles about 12v battery problems. Car monitors the draw voltage etc.
does this is the same with old model s?
I think new teslas has different 16v batteries? And smarter systems.

what should i expect when i hook it up directly to the 12v battery. 370rms amp and 350rms sub. Problems?

No problem on the pre-refresh cars. They are still 12v. I had about 1500w split between two amplifiers connected to the 12v battery in my 2015. Ran great for 3 years before I sold it.
