frequency response on HUs
The answer is basically no it won't play the extra hertz.
The point everyone else is sayig is that it doesn't matter.
It is really dependant on who you ask though since some people might claim that the higher up frequencies can not be heard but be felt ect ect.

Actually speakers are rated with +/-X db as well.
I think your theory is seriously flawed. Wouldn't amps, speakers, HUs rated at flat from 20-20K be better?, Or even +/- 1db would be better than what you state as 'all is good' .
If your head unit is -3DB at 20K and your amp the same and your speakers the same....what do you think your final result will be?

If the frequency response of the system.....HU, amps and drivers, extends beyond the ability of your ears to hear it, does it really matter? If your dog complains about the "highs" tell him to go buy his own.....
I hear you Dave, some people on this forum do not understand that what is happing an octave or two up from 20K makes a difference to the 'audible' range.

Not every response needs to be quoted from a text book nor does it need to go into every detail and every side detail around a topic to allow someone to get a better understanding of a topic.
If would make you happy I Could explai every technical naunce on the matter but it would probably not do much to answer the OP's question.
welcome to the "Real World" where every sound system isn;t absolutely top of the line. The OP doen't seem to very experienced yet and I was trying to keep everything simplified and relevent for easier understanding.

Dude, my response was far from technical and hardly from a text book, it was just based on over 20 years of buying(for an electronic retail chain), selling, repairing and wholesaling audio equipment. It was about as simple as could be explained. If you want technical lets discuss psychoacoustics!
mentioning that 50Khz makes a difference intothe perceptions in the audible range is getting into psycho acoustics. Fact is the OP isnt building a competition level SQ system. 99% of the equipment out there is all rated +/-3dB except for the very high end stuff, so I felt no need to get into the total rating system.
And yes you can suffer severe hearing damage even from frequencies you cannot hear.
To add to things, many manufactrers products very much exceed their 20-20Khz linearity well past the 20Khz mark, but don't advertize or test the specs past that point as 99.9998% of the world would now the difference.
Alot of lower end brands have begind andertizng 5-50Khz to make the uneducated consumer believe their product is better. Much like amplifiers and speakers, Musical, and Dynamic power ratings.
When buying commonly available, non-super high end equipment the 20-20khz +/-3db spec is pretty much all that is offered in terms of specs.
this can all go on untill Jesus actually makes a comeback
