Should do just under 10,000 watts per amp into 1ohm
A few others have asked the same question - where the fuck do you get 20kW from in a car with 12V wiring and perhaps a 1kW alternator?
Unless, of course, you plan on towing one of
these behind you
Edit:
I am not certain but I thought on the highr power units they required a 24/36v/48v supply opposed to just 12v?
OK, even at 48V that's over 400A without taking the amp efficiency into account.
But, see above, where do you find 20kW in a car?
