[QUOTE="soskie, post: 6992960, member: 622155"] sub-1150 rms 4ohm dvc ( its wired to 8 ohms) amp- 2x 400rms at 4 ohms (have sub bridged, so 800 rms) Im trying to find out how many volts i should set the gain to. Do I use the subs resistance or the amps? Sqrt(Power*Resistance) = Voltage Sqrt(800*8) = 80 Sqrt(800*4) = 56.56 Thanks in advance:) [/QUOTE]
