You know anything about OHMS law?
Well, let's do the math...
P = E * I
where
P = Power in Watts
E = Voltage in Volts
I = Current in Amps
Or
2000 = 12 * I
Solving for I
2000 / 12 = I = 166.667 Amps
Most car stereos are not honestly rated in power that they can generate continuously. Matter of fact, neither are home stereos. It is the biggest scam ever when they say that "yadda yadda is 2000 Watts"!
Look carefully at the continuously rated power output. This is the power that a system can deliver continuously with a constant sine wave running through it.
So, you plan on actually listening to music instead of a tone? Power will be peaky and not constant. If you are going to try to pull 2000 Watts continuously, you'll need battery cable to power the amp and an alternator that can supply 170 amps.
My guess is that you will need an alternator that can supply 100 amps or more when charging and those peaks will be supplied by the battery when they occur.
I hope that you won't be sitting in the car when this thing is on!!!! I have a 75 Watt system in my 03 Mach and it is plenty loud!!!

Thanks for doing the math. I never was good with numbers lol.
BTW- theres no point in building the system if Im not gonna be in the car!! It sounds awesome in there!!
