yeah well I dont have a 9V input so I am not getting full power. the input off my alpine deck is only 4V.

thats EXACTLY WHY they put a gain nomb on, so you can match the input voltage to get the full power outa your amp...

wow did i ever screw that quote up

 

yes i know why the gain **** is there. and since i have the gains low (even for 4V), it should not be running at full power.

 

I've read many times before that the gain is not a volume control. I understand that it basically acts like a signal sensitizer/desensitizer. So if you turn the gain in one direction it will increase the sensitivity of the incoming signal and likewise it will do the opposite if you turn the **** in the opposite direction.

So let's assume you're gain goes from 100 mv all the way up to 8 V. This means if your gain is set to 100 mv then your amp will produce full output with an incoming siganl of 100 mv. Likewise, if your gain is set at 8 V then your amp will produce full output when it receives an incoming signal of 8 V.

Therefore if you have your gain set at 8 V and your deck can only produce 4 V then obviously your amp will not be able to produce full output. Let's not forget that this is assuming your deck is turned up to the max. What would happen if you turned the volume on the deck to 10% ? Your deck would produce an outgoing signal that was roughly 400 mv. And now your amplifier would hardly produce any output because the gain is still set at 8 V.

So it is possible to decrease the output of your amplifier by using both the gain on your amp and the volume **** on your deck.

 

wow!!!! Sounds like Luckyman just finished a mobile Dynamaics course and couldn't wait to share that tidbit of info!!!! LOL

 

LOL !!! Actually, several years ago I studied audio engineering, and before that I studied electronics at DeVry. I'm great at starting progarams but I rarely finish them. I get bored very easily.
