Model 3 Performance sound system upgrade

We have seen some owners do this to their M3 with the base system - upgrade speakers, etc. It is “doable” but probably complicated as EVERYTHING is software based. 
This company does it:
Reus Audio V.2
Reus Audio Systems | Car Audio Design Custom Audio for Most Luxury and Exotic Cars
www.reusaudio.com
Someone on these boards has a system installed by them.
No idea what is involved.

It's absolutely possible and heaps of people have done it. It's no more difficult or complicated than a "normal" car, except there are a few minor differences. Search these forums and you'll find tons of info. I used Travis Llado's blog as a main guide. Link below.
The main things you need to know:
- Take 12v from the penthouse under the rear seat. This is good for like 2000+W or something, and will prevent 12v battery errors. Read up more about this first if you're unfamiliar.
- Last I checked, no one has managed to decode the digital audio signals, so you need to take direct analogue speaker level signals, and feed them into your aftermarket amp.
I personally replaced all of my speakers, including a new sealed enclosure and sub, plus added an amp for the new sub and front door speakers.

- Amped Garage wiring harnesses & 3D printed speaker adapters - highly recommend
- Focal ISU-200 8" woofers - front door
- Dayton Audio AN25F-4 Soft Dome Tweeters - front door
- Dayton Audio ND25FN-4 Soft Dome Tweeter - center dash
Waiting for 3 x FaitalPRO 4FE32-4 4" full range speakers to be in stock for dash. Good improvement so far for relatively little amount of work.

What did you do for the power? Did you use an isolator?add another battery? I read some getting an alert about power draw when connecting the amps directly to the 12v battery.
