Maximum ampere for aftermarket amplifiers

[mirko88]

I'm going to replace the Tesla sound system by audiophile level high end components, but need to know what amperage the Tesla can take for the amps I need to install.
Of course I can choose between AB class or D class amps, but even 2 big D class amps can put a load on the 12V system.
Tesla doesn't provide any clear details on how many amperes can be safely 'added' to the current circuit, but perhaps anyone has experience with adding an aftermarket stereo system?
I obviously don't want to kill the 12V circuit of the car....

Any help/info is highly appreciated.
Thanks

I'm using 2x JL HD400 without issues if that helps you.
