Quick gain setting question. I am running the 1000D on a AA Havoc, which is a 1200W rms driver, at 1ohm. When I set the gain using the DMM method to attain an output of 1000W with at an ideal 1ohm load the VAC reading should be about 31.6. However, at this level the output of the driver does not seem to be anywhere near it's full potential.

When I actually measured the impedance of the sub wired at "1ohm" it was in the 1.2-1.4ohm range. So my question is should I use sqrt(1000*1.4)= 37.4VAC instead of sqrt(1000*1)=31.6VAC when setting the gain? Also, how do you normally factor in the bass boost, LPF, and sub-sonic filter settings when setting the gain?

Thanks!!!!

You measured the direct current resistance of the coils. NOT the impedance.

The amplifier will output 1000w into 1 ohm, not into 1.4ohms or 1.2ohms.

Bass boost is set how you will use it (it's a useless feature imo). LPF and SS should be set so that they don't "interfere" with the tone you play when setting the gain.

Is the amp running out of gas? If the answer is no, you can keep turning up the gain until it does, then don't go any higher than that....

If you can't tell when the amp runs out of gas, set the gain wherever you want.... And buy an extra woofer...

It is that simple... Seriously.... You've wasted a bunch of your time already... Quit and enjoy your music...

Thanks for the replies. And I know exactly what you mean by the "amp running out of gas", the point of diminishing returns where turning up the gain yields little to no additional output.
