Just to be sure, I have amp7 and amp2, which will be powered by one supply

so rail voltages are the same, now my question is, is ground for 5V on amp2 and 5v(8-12Vdc) the same?

I was thinking of using voltage (8-12V) for amp7, then use 5v regulator to drop down to 5v for amp2, but ground for both is the same. That is ok, right?
supply voltage is the same in any case..
