Can someone calculate this for me?

Hey guys,

Im trying to find my voltage to set my gains. I know that Im supossed to do:

RMS X OHMS then SQUARE ROOT, but looking at the birth sheet, my amp puts out 2237 rms watta at 2 ohms which is my final load for my subs. However, on the birth sheet, it shows the "Supply Voltage" was 13.8V, not 14.4. Does this make a difference and if so, what would my final voltage be in order to set my amp gains properly?

Thanks

Output is output, regardless of input voltage. The potential output is higher with a higher voltage input, but since you're measuring in volts out, then the input voltage is irrelevant.

ok. so I guess Im looking at : SQ ROOT of 2237 X 2 = 67 volts

(2237 x 2) sqrt = 66.8 volts.

I would avoid rounding up.
