I am super limited on space and im doing a 1.75 cube box behind the seats in my single cab 93 ranger (no room).. box is 50x13x4x8 wedge with 4 being top depth and 8 being bottom depth. I am using .5" MDF or Birch and am invert mounting an SPLaudio type X 10 on the box so that "dat a**" will be chilling between the seats (no center console). I will be running around 1000w+ to it and want to tune the box to 28hz. I would like to use a PVC port due to price and dont mind shooting it out of the box or w/e. What do you guys think?
