New Build (2) Fl Btl 18's

[Mostar]

I just built my enclosure for my BTLs. I was woundering if I am going to loose alot of pressure due to the fact that about a quarter of the port will be directly firing at the rear glass on the lift gate of my '05 GMC Envoy? Here is a pic of the enclosure. It will be right around 13 ft^3 after displacement w/ 166 in of port area tuned to around 35 hertz.
