guys, my HU has control for the phase, gain and crossover of the sub. It is paired with an Active Sub. The active sub has control for phase, gain and crosover too. The HU has a 6.5v output.

What should be the position of the phase control of the active sub so that i have room/choices to control the same from the HU. How do i make them match.

same question for the gain and crossover.

thanks
