No, i don't need to know how to set the gain....I found this acticle by accident and was wondering how accurate/inaccurate this is. I never heard of any of these things so i was wondering if they were correct. I don't think that it is but maybe i'm wrong. I read some parts of the other articles on the site to see if they were accurate and seemed ok.

Wow. That is no where close to correct in any way, shape, or form.
Quote from https://www.teamrocs.com/technical/pages/gains.htm
"Its not rocket science to set the gains. Gains are like little volume controls, (I don't know why so many installers are taught that gains are NOT volume controls, when in fact that is EXACTLY what they are!) its super simple to just set them where the level sounds good to you."

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
That's the preferred method for gain setting if you run a retail business: it's sure to cause your customers to come back once they've blown their speakers. Just make sure you sell stuff with no warranty for stupidity.

Support the12volt.comI think he was trying to "dumb it down", but it didn't come out quite right. There are a couple of other articles he's written that I have saved to file...one of which has been referenced by members here for awhile:

Some of what he says about adjusting gains has an underlying truth. You want to have a good amount of play in your deck volume knob. And you do want to be able to get to a point where you feel you may have turned it up too loud. Those are things that appeal to a human's psyche: the tactile feel of the volume knob and the aural response to the sound, causing one to feel responsible enough to turn it down a little.
Setting gains (properly, as we prefer and without referencing them to volume knobs) will give the user the same results as he stated in the article. Setting the deck "high volume" to about 3/4, or better, finding that high volume point using test tone sine waves in order to be more accurate, allows the user the tactile feel of turning the volume knob a good travel length while enjoying his music.
In my car, I'm using the factory deck because it's a PITA Taurus and deck level tops out at the halfway point. So my amp gains are set with that as the high point. I miss out on that feel of "turning the knob up". But a good aftermarket deck will allow that full 3/4 turn, and more.
Then when the user gets it too far past that point, the senses kick in and he listens more closely for signs of distress in the music and the speakers. It's a natural thing. The article seems to try to make something that is very technical but really simple into something very simple and not technical at all. The amp gains are not volume controls and shouldn't be looked at as if they were. If a user truly were to believe that they were, what's to stop him from going to the amplifier and turning those little volume knobs UP whenever he felt like it? Setting gains IS science, but some science is a lot of fun.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

That makes some sense...I read some of his other articles and he seems to know what he is talking about. Just the way that he said it came off like he had no clue.
