i would go with what the amp rates so you dont blow anything but if you think its less then look at what the internet ratings are look up the model and see what other people say cuz if it puts out 1200 at 1 ohm that doesnt mean that it doesnt only put out 300 at 2 ohms

I have a hifonics bxi1206 which is supposed to put out 1200w at 1 ohm. I know they are over rated, so how many watts should it realistically put out?
youre lucky if you get 800w rms at 1ohm

whats the fuse rating

8-900w rms....... 1200 if lightning strikes the amp while playing some steely dan during a smoke session with a blind midget stripper

it wont get neer 1200 watts like pitbullx said I.L.S. (if lightning strikes)
at 14.4v w/ 80% eff. you may see low 921 w/rms
at 13.8v w/ 80% eff. 883 rms
and the chance that, that amps is 80% eff. is slim to none. more like 70%-80%. you can also get a ballpark with a volt meter. put the meter on a/c volts playing about 50-60 hz.
voltage / ohms = amps
voltage * amps = watts

example: 50v / 4 ohms = 12.5 amps
50v * 12.5 amps = 625 watts

thanks for the info. I did a little reading about setting the gain with a dmm. so if the amp is 70% efficient and putting out like 800wrms , when playing a 60hz test tone I should adjust my gain until my voltmeter reads 28-29 volts with the head unit at 3/4?(amp is seeing a 1 ohm load)....is my math right? I used a formula I found on the12volt.com
voltage= square root of (watts*ohms)

ya to find the eff. just take the watts that goes in to what it puts out, divide the 2 and that will be your eff.
