Message: <blockquote data-quote="digitalrainman" data-source="post: 3154287" data-attributes="member: 577603">i just adjusted my gain on my amp for my kicker cvr 12 2ohm sub i just put in.  The amp is a crunch amp that states it can do 450x1 @ 4ohm bridged.  So for my calculation the voltage should be sqrt(400x4) = 40volts.  I adjusted my gain to 40 volts by using a dmm on the speaker terminals.  I only had to turn the gain knob 1/2 of the max.  My question is, is this normal?  The reason i am asking is because i was trying to push 400 watts out and the amp maxes at 450 rms, and i only turned it up halfway.  I put it to full to get a voltage and it went to 69 volts, which would be 1190 watts. This sounds odd to me, but then again i am new.Also another question was is this the correct formula i should have used sqrt(400x4), since i am running my dual 2 ohms on the sub in series and its providing a 4ohm to the amp?</blockquote>
