my statement came from my own testing..
on a friends vehicle with 2 JL 500/1's; one wired to 2 ohm, and the other wired to 4 ohm.
Amp A, wired to a 4ohm load obviously required less amperage to produce the 500w, than Amp B wired to a 2 ohm load, but I had significant voltage drop at the battery occuring on Amp A, wired to 4 phm, whereas I didn't have the problem with Amp B. (these amps weren't running at the same time)
I even switched them amps, so that Amp A was wired to 2 ohm, and Amp B wired to 4 ohm, just to dispell and manufacturing differences.. the outcome was the same.
So I will ammend my statement to, read, that more amperage would be needed from the charging system running at 1 ohm, opposed to running at 4 ohm... in the end I would still rahter run my amps at a higher impedance, as long as I could get the power I needed at said load.
