Start with reading the sticky subject above about how to set gains. It doesn't matter that your head unit "is 2V" and it doesn't matter what numbers are etched around the gain dial. And disregard the digital LCD display on the amp.

When you set the amp gain to match the deck output, you will be listening for a tone deviation in a controlled test. Wherever you find that golden spot is where you leave the gain dial...no matter what corresponding voltage number is associated with the setting.

Otherwise, the settings you listed above look to be fine.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
