i know these are overrated so does anybody know what the rms at 2ohms on the alpine 400 watt mono amp is??? i think i've seen somewhere around 430-450ish but am not sure. i'm trying to set the gains on the amp and want to know the correct volts to tune it to. anybody w/ experience please chime in. thanks!

alpine is usually pretty realistic in their ratings. i would say a solid 450 with the car running.

maybe less if the car is off

yeah. 12v should be right around 400. 14.4 might be around 450

cool well i'll just set the volts for 400 even to be safe.

thank guys!

any other comments are still welcome though.

420wrms @ 2ohms = 29v

400wrms @2ohms = 28.3v
