Default How to setup new head unit with stock bose and PAC roemvet1

Setup any front cross over in HU to allow full pass of signal. Rear speaker check spec. Mine could go down to 40hz so set those to full also.
Adjust fader to all up front and to one side. Turn adjustment screwa so no base. Should be counter clock.
I used a phone app connect through bluetooth to generate a signal of 100hz. App was "frequency Generator"
Set SPL C and fast response. Dial to 80db
Set volume until I could get meter to read at 80db on all speakers then put back to front left.
Set frequency generator to 40hz. Did not touch volume.
Now I started to adjust the pots in the PAC unit until the base read 80db.
Switch to right and did same thing.
Put to center and had to back them down a notch.

Now test with music. My sub are now not over power and it sound awesome. My finial adjustment is with the arrow on pot pointing down.as per picture.
