tell people the gain knob = a volume knob and they crank the gain. these people typically have a subwoofer and a HU with 6x9s. suddenly the bass is very loud and the speakers aren't. this is because the high gain or "volume" allows the subs to get very loud at 5/30. the 6x9s running from the reference are quiet. to get vocals requires a volume of 15/30, at which point the bass has not gotten much louder becuase it is clipping.

otherwise its just a pointless argument. the settings, in use, are dependent on each other. low volume * high gain = high volume * low gain. if you allow a full range of volume settings, the gain must be restricted to a limited range. if you set the gain to a high setting, the allowed volume range is limited. if you set high volume and high gain it just doens't work and you get clipping. its really based on what reference you want to set for your system -- build around a fixed gain, or build around a fixed signal.

i do like the HU's volume control for its ability to control the volume of all amplifiers, and for this reason, I set the amplifier gains based upon the HU, not the other way around.

Especially when you have an active crossover

I dont feel like adjusting the mids, tweeters, and sub every time

i can do that on the h/u.

So explain that to a noob and they will understand how it works... and will probably understand how to set it.

And no, high gain/high volume does *not* mean clipping... I've had amps that needed a high gain to do anything, and I've had HU's that put out next to no voltage... if the gain needs to be maxed, crank it up.

People read that and get scared to turn the gain up... //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Don't leave it at "its a volume control" or, "its not a volume control"... tell the noob HOW TO SET IT AND WHAT IT DOES. Don't "dumb it down", doesn't help anyone.

we did, jmac made a sticky in the amps section for it

I enjoy helping new guys ( noobs as you guys call them ) Been helping for years. I am always for showing how to do something rather than doing it for them //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I always looked at Gain as a power regulator of sorts..it regulates the output of power to the speaker - every system wants a little different power for variations in set up,speakers HU etc.....

I dont see why there is so many pages on this subject,its not rocket science

If you were to talk to the tech that designed the amp, he would tell you exactly that. He would also tell you what the maximum input voltage would be to allow you to use the full range of the gain dial as a volume control without clipping the amp. If you really understood this stuff rather than just regurgitate the absolute basics that are taught at the installer schools, you would know that. The schools teach you the very basics of doing a correct install. If you want to do more than that you are actually going to have to learn on your own.
BTW, I'm from the old school, too. The equipment from the old school is not the same as the stuff today. There are new things out there that aren't going to be covered in a basic install course.

Older doesn't necessarily mean smarter. All too often poeple get stuck in the old ways. Look at engine tech. I ride Harley's, and the sheer number of old guys that have been around them forever and swear by carburators is astounding. The fact is that a modern EFI system will produce more power more consistently with less fuel consumption and fewer noxious emmissions than a carb could hope to. But you will never convince the old guys of that.

Will you marry me?

Thats what i said some 2-3 pages back

I'm proud of myself. I just read all of this, not sure if anything was "gained " from it but I did read it. All 13 pages. And got paid for it.

Scott.
