Question About Setting Gains?

I have read the amp setting tutorial on CA.com and it says to play a 60hz tone and set your gains to the AC voltage for your RMS. My question is wouldn't it be better to set the gains based on your box tuning because the amp puts out more power near box tuning to avoid clipping or would you still use a 60 hz tone? Like my box is tuned to 40 hz wouldn' it be better to tune my system with a 40hz test tone? Correct me if I am wrong, please and since I listen to rap I should use a -3db tone right? And just wondering does anybody know what db tones are used on Bass Mekanik Quad Maximus? Could I use that to set my gains safely?

Actually the best freq to use would be 1000 herts (highest output), but most sub amps won't play that high.
But in your aplication 40 or 60 would be fine. The difrence would be so minimal that its not going to overload your speaker at your boxes tuning freq.
Just make sure you set your gains with the subsonic filter turned off, ESPECIALLY if you use a 40Hz tone.

While I can't answer the question of what tones are on the Bass Mechanik Quad Maximus I can tell you that you can use a test tone of 40 hz to set, since your's is tuned to that. I normally recommend between a 50- 60 hz tone myself.

I hear 60hz all the time so I will use that.

I am just going to use a -3db 60hz tone. Do I need to turn the Sub Sonic Filter and LPF all the way down to get a good accurate reading?

do not use an attenuated tone.

What if 60 Hz is outside the recommended range of a set of speaker components? Say the components recommend 70 hz-20khz output. Should I use something a little higher than 60?
