Ummm, you'll probably need to upgrade. At 80 percent efficiency (and that is probably a pretty close guess for a digital amp) it can suck 105 amps from your power supply (alternator and battery) I know you won't be using it cranked up ALL the time, and it will not be using that much all the time, but even if you run it continuously at (average) half output, that is still 52.5 amps, which really does not leave much power in reserve to run your AC, seats, lights, engine, other amps (if any) etc. Look into upgrading it, to somewhere in the 150 amp (or even more if you want to spend the bucks on it) range.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

yeah i understand. didn't really want to do that and i divided the rms by 12.7 and it came out to like 90 something. the alternator is a pain in the @$$ to change in a jeep don't want to do that.only if its my last resort.
