I would have loved to learn the correct way to do this with a multimeter. However I went through and did what you described to my amp with the multimeter and a test tone and the voltage that was produced from my amp was not anywhere near what you were saying it should have been which I believe was 47.94 volts. I spent that entire day trying to figure out WHY it wasnt working for me. Perhaps I was doing something incorrectly, I dont know. I mentioned the reason why I think it is a waste of time which you havnt given a response to. You being a professional in this area should know the answer. The question or statement im referring to is that amps produce different voltages at different tones etc etc. Now perhaps there is more that goes into it, but from the standpoint I was at, and any other "beginner" is at, is the difficulty in doing this procedure without having somone who knows how to do it there with them. That is another reason I referred to it being a waste of time. I am also going to refute your comment about being lazy. I tried very hard to get this to work. I consulted people on this forum, local shops, kicker, and JL audio. Each person told me different ways to set the gains. After attempting many ways I decided to go with my standby and do it the way i have been doing it for several years. From a professional standpoint it may be wrong, but its what I know and it works. In all seriousness I would love to learn more about it however I cant afford to take college classes, which I am already taking a loans out for anyway. Although this forum is probably the most benificial thing I have found for mobile audio, some things I would just learn better seeing. Beginner in using a multimeter, yes, what I was refering to was car audio in general. I am going off the definition that beginner is someone who starts or BEGINS something. Amateur is someone who enjoys it as a hobby or pastime.

xTimx- If you cant find a place that sells test cd's you could get a program called NCH tone generator. You would need to have a cd burner though. I dont want you to think that I think you shouldnt try this. You can learn a great deal just playing with it, and if you listen to what some of the people on this forum say, people like DYohn Forbidden stevedrt and several others you are going to learn a lot.

You can download this trial version sine wave generator and make a CD of test tones in a couple of hours.  I used it to make one, check the help menu for recording sine waves.  You can record the .wav files for as long as you want, so for testing make some files at least 5 to 10 minutes long.  You don't have to pay for the shareware, just make your CD while it's free.

You mean something like the automatic foolproof amp gain setting robot?  Not telling you about that one!

AW C"MON STEVDART, PLEASE! i'm sure EVERYONE would like to hear this one! including rob and dyohn! :P but that would be so cool to have...(snaps out of dreaming)
i have another Q. is there a tone that would be the same as another tone. for example if i'm needing to get 1khz, is there a hz for being the same as 1khz (1khz=380hz?)

1 Khz = 1000 Hz
