that way u would have time to tune your amp as it plays

 

[hatedonmostly 5,000+ posts]

gain all the way down, settings on the hu (bass, etc) all the way down.

set the hu to your listening volume. usually 75% of maximum

play 50 hz 0 db tone, turn gain up until it reaches that voltage.

By doing all of that, It is 750 @ 1 instead of 1200 @ 1?

does that apply to the 2000k watts at 2 ohm to or what voltage would i be looking for ?

if i had a sub with 2000 rms and was looking to tune it would i still want the voltage to be at 34.64 ?? tuned

No, you would need to follow the Ohm's law equation, which, as Bumpin Goalie listed in post #4, is voltage=squareroot(rms*impedence)

oh and it would be at 2 ohm

Given that you want 2000 watts @ 2ohms, your voltage would be ~63.24

u would want a tone that last that last like atleast 30 seconds or so instead of repeating it . im sure thats what he meant

Forgot to mention this, very important.
