[QUOTE="aLCHeMiST45, post: 2224952, member: 571136"] I am having a great deal of difficulty when trying to set my gain using a DMM. I have a Directed D2400 powering (2) 4 ohm DVC Kicker CVR. I am planning on wiring the subs to a 1 ohm load. Each sub RMS is 400 watts; a total of 800 watts needed to power both. When using the formula to calculate desired voltage: Sqrt(Power*Resistance) = Voltage Sqrt(800*1) = 28.28 volts Regardless of how high the gain is set, the AC output never measures anywhere near 28.28 volts. I am testing using a 50Hz test tone @ 0dB with volume set to maximum for listening. I have actually turned the gain to the maximum and it still does not measure near 28.28 volts. As far as bass boost is concerned, I have tested with bass boost on along with the gain set to maximum. The voltage does not come close to 28.28 volts. Another thing I am questioning is the fact that I have no voltage reading from the speaker outputs until the gain is above half. I do not have my gain set at maximum, I was testing for different speaker output readings. Could someone please help me? [/QUOTE]
