i havent set gains in a minute and need to clarify some stuff. i have an IDQ 12 D4 matched with a pdx 600.1. so if i want 600 rms, i do the calculation,

voltage = Sqrt(power x resistance) which would be Sqrt(600*4) = 48.9.

or....

voltage = Sqrt(power x resistance) which would be Sqrt(600*2) = 34.6.

which one is correct?

how is the sub wired? 4 ohm load would be the first one. 1 ohm would be neither of the two.

a d4 sub you can wire at 2 ohms or 8. so you wanna do the 2ohm one since you will be wiring the sub to the amp at a 2ohm load. use this:

thats what i thought but i got confused with the resistance. thanx for the clarification.
