What tone does every body use? Setting amp gain

[Ernesto]

I personally use 50hz (0db)

You set your amps with music? Do you use a DMM or you do it all by ear? A shop hear did it like that by ear and I didn't think any one else actually did that.

I use 50hz -3db ...what's the real difference with the 0db and the -3db...the -3db tone is MUCH louder than the 0db..so if I used the 0db to set my gain, shouldn't it be higher than if it was set with the -3db?

do it all by ear, i break out the ac rta every once and a while.

for the most part its all the ear.

Pretty good..I've only done 1 car by ear so far and that's my friends car...Playing young jeezy Thug motivation 101...so far so good

I used to do it by ear, but my hearing is soooo messed up now that I now use 50hz tone.

(im not kidding ask steve I have real bad hearing)

50hz tone on class d amps , and 1000hz tone on a/b amps

using a dmm and the equation sqroot of (impedance X Power desired)

all 0db tones, i read -3db can damage equipment if not used properely, i dont know a lot about it but i stay clear of that until i know how to use it for sure

i set mine by ear too when theres not multiple bass amps.....

when dealing with MBA (see above) i use a dmm and 50-60hz depending on how i feel.  I dont have to do that w/the new RF amps though.  Set one gain and they all follow the leader (master/slave)  it fuckin RULES im tellin you.

say when you do use the tones to set the gain... do you use a -3db or 0db and why?    oh and also can you explain me the master/slave stuff? I got a t4004 on the way .. so all the t4004 amps(general example) that are attached to the intial t4004 will follow the same gain setting if I set this one to master and the others to slave?
