It's a four car with a trunk. The back seats has an arm rest that folds. When the arm rest is down, there is a hole that goes throug the cabin from the trunk. I wanted to face my 8" sub toward the front of the car so it fires into the cabin. That way I can also put the amp on the back of the box. Does it really matter which direction the sub face? I don't have the sys. hooked up yet, just wanted ideas before making the plans.
