Thinking of replacing stereo - '99 Boxster

[shacky]

I noticed difference in preamp voltage on these two. Is that real and does it make a difference?

I just asked Crutchfield and they said my car without nav and with door speakers already has factory separate amp. I did not know that?

Is that true and where is the amp located?

In the frunk, just behind and above the spare tire towards the battery.

Is factory amp good or should I consider upgrade?

That's a bit of a loaded question...."good" is subjective and relative to what you hope for as an end result. If it works, keeping it is the most cost effective (and easiest) option. If it doesn't work, or doesn't work as well as you would like it to (ie power output), then the obvious answer is to replace it.

Personally, I'd start by replacing the head unit and speakers and see how you feel about results...if good enough, then keep it. Another alternative is to design your entire system from scratch...matching speakers to amp (and/or crossovers)...this is going to be the most expensive (but best) option...just remember this IS a convertible and isn't the best car for sound staging.
