line driver after the EQ... cool or not?

My question was genuine, what are typical overload points for modern amps (I am assuming older amps will have lower clip points since the input voltages are higher now than15 years ago.)
Since we are talking SQ, I am not sure I am sold on a HU output voltage over 4v, I think there is a smaller opportunity for noise intrusion on the long stretch of IC between the HU and the amp. I am just not a big fan of line drivers, I don’t get the point of an extra piece of gear in the signal path. I really haven’t thought this through but I think they are a band-aid for a poor HU design.

George needs to know better what your question is. George thinks you are asking what is the point that the input stage of a amp will clip, if this is the case it depends on every amp cause they all accept different amounts of input voltage.
George does not believe in line drivers either if the head unit is designed properly. George knows that each output section has a output inpedance and this is the ability to sustain the same voltage at the head unit as it does at the next component. George remembers years ago Sony had a deck out (CDXU8000) that had 4 volts out put had a outragous output inpedance of 10,000 ohms which meant by the time the signal got to the end of the RCA it had no were near 4 volts of signal voltage.
George hopes that explains things.

Why do you need a line driver ?
1: The output of a component will not drive the input stage of another component to to required signal level
2: You have a signal to noise ratio that is to low
causing noise in your system
Figure out where you need to put it and place in as needed. Most common is between the deck and the next item in the chain.
