this all these car audio dogmas set along the years people got used to not think as much as before anymore.

You listed the equation?? Musta missed that one.....
An amp's output is determined by the voltage rails, and even more specifically the transformer... You can add 3db to the amplitude of the signal, but that doesn't make it any "louder" OR make the amp produce any more power. When you have entered the realm of clipping at the amp level you have exceeded the amplifiers capabilities of increasing output. Power=ouput. When the amp is clipping, it is outputting its maximum available power (either battery or alternator, off or running repectively) and it simply cannot produce anything more unless internal components are changed, or more voltage is available from the source. Am I missing something?

For example, are you telling me that if I add 8db to say, what.... 80Hz via my EQ curve and drive that frequency into clipping that it's going to produce more power and thus more output???? I highly doubt that. Much like the thought that if I turn my deck to max and then crank the gain it's going to get louder
. If you drive said 80Hz note into clipping then the power output will absolutely go up. It will be non-linear, but it will definitely go up.

EQ, bass, treble,bbe is essentially a volume for specific frequencies.
Whatever frequency you boost will end up clipping earlier as you raise the volume.
Using bbe is fine, it helps make the sound fuller at low volumes since the ears don't hear the same at different volumes. It's when you turn it up that the benefit disappears.

Tell the "sales clerk" that it might be best for him to change to selling washing machines and stoves now and that you will continue to purchase your stereo equipment from people who are 12volt literate. I too will send you a cookie with your parts bags.

He basically only said all of that to try and get me to by an amp. There amp selection didn't fit my needs and there selection is really minor.
Any news on those parts I mentioned?
I will get the money order ready...

3dB higher for a square wave, actually, but won't reflect on actual amplifiers due to their power supply voltage drop.

When an amp is clipped, it is drawing directly from the transformer and thus voltage rails. That means it is essentially drawing directly from the battery/alternator (causing further voltage drop). Clipping is dangerous for amps for this reason because that much current flowing through those type of components unchecked will burn things up. Usually, the voltage drop associated with this is enough to shut things down, negating any possible gains anyways 
If you happen to have a power supply that can handle delivering power to a clipped amp you run the risk of burning up the amp, as it will continually draw at or beyond it's safe capabilities
