I know nothing of how most this **** works. BUT, keep in mind that if your radio is rated at say, 2v, and your amp is set at 2v, even IF the voltage is changing, they'd change together, would they not? So they'd still match.

I'm sure there is a lot more science to it, but, that's just how I interpret it.

Amp is essentially independant of the headunit so maching gain to headunit voltage is pointless. The point of the amp is to AMPLIFY the headunits output. I have never matched gain to headunit voltage and never saw a need to.

And no the voltage change wouldn't be constant. You have a 2 or 4 gauge wire hooked directly from the battery to the amp. The wire feeding power to your headunit is probably 12 or 14 gauge and run thru a series of relays and probably only sees 10-11V on a good day, so you are always going to have more power at the amp than the headunit.

EDIT: I should add you set the gain to your subs power, not the headunit power.
