Wondering how mucb power i could push on mt stock electrical system.

[Darinf01]

So I am trying to add subs to my 2017 mustang gt premuim so it has the 200 amp alternator. I have a 6 Farad power cap I wanted to get some thing that would push some like hard bass. I wanted to do an enclosed back seat that I can just put my back seats forwards and I can see my subs and the port possibly and that I can still close my backseat up just trying to gauge how many watt rms I'd be capable off running.

With nothing else electrical running in the car, I'd say close to 2000 watts. But that's no heat or ac, no lights, etc.

I have a 2006 Mustang GT and the alternator amperage is 135. I'm running 3 amps totalling 1600 amps, driving 2 subs, 4 - 6x8 and 2 - 6.5. Ive been runnig them for several years with no problems. As previously stated, you should be okay around the 2000 amp range.
I also have the same setup that you propose for the rear seat. I built a speaker grill to cover the opening created with the rear seats down, so the sound from the subs is not dampened.
