This method of adjusting the gain is back yard tactics. And the gain level (you mention 5/8's) is only relative to the install. The PROPER way to adjust the gain is using a volt meter at the terminals, then converting voltage out to Watts. Then adjusting the gain to the target Wattage for the speakers. This will all depend on the input current to your amp (which is why the gain level is only relative to the install and not an absolute of 5/8 for every install).
But you knew this, cause you're a professional installer
