I know that box isn't tuned to 63hertz either. Turn the frequency knob to your boxes tuning frequency. In fact change your settings so that they look like this.

Set your Sub level on your headunit to zero or flat and leave it there forever. And turn the Q bass level on you amp all the way down too and leave it there. And the usual, set the X over to LP and set the X over frequency to around 70 hertz. While you have some very nice equipment, I have a feeling your not super experienced in audio so we're here to save you from awful distortion and potential clipping destruction. I would turn your sub amps gain to 1/2 or 2/3 the way up and leave the Q bass on your amp at zero. Leave your head unit sub settings at zero or flat. And use only your BP.8 processor to add boost at your tuning frequency, which you say is 35 hertz. The BP.8 has a stupid high Subsonic filter so turn that all the way down on your knob. Turn the bass level all the way up on your processor knob, and put some music on at your normal listening level. From zero, slowly turn the boost level up on the processor until you start to hear distortion, then back it down a touch. Leave the processor alone and now all you have to do to do to turn your sub level up or down is turn the bass level on the knob. Get what I'm saying?

EDIT: Also on the back of the processor is an output voltage switch, set that to 7.5 volts. If you think you have a firm grasp on everything I just explained then you can set it to the 10v+ setting. and make sure the ATT button on the end of the amp is pushed in too. Man I love precision power.
