Bilal bro, 2 things I would like to point out.
1) If you are aiming for a sq setup, you do not need to push that sub. You need to let it blend in. The Low frequencies from the sb should not overpower the midrange, rather fill in the gaps. To have it tuned properly, set all settings from the pre to flat ( eq flat, sub ON, sub level 0, loudness 0, sla 0, HPF off and set the sub cutoff at 80hz ). Listen to some sq songs ( download a few, make sure the bitrate is 320kbps ) i.e Hotel California or Horses by Tori Amos. See how the sub performs. I'll post a video of Horses and you should get an idea.
2) This is new setup. Let it break in. Playing it at those volumes will damage the moving components in the drivers. This is a debatable topic but time and again, its proven to let moving components break in. I would suggest not to run the setup over normal listening levels for 5-10 hours of playing time.
