I did search without finding alot of info.Let's say  i want to put a 8 in sono on the top sheet of my box (sig) i could get around 3-4inch of clearance. Would it affect the performance in any way? if so, how? affect tuning or port noise?And in general, does aero and sub on top works well in hathback? there no other side i could get clearance except the side, near the back</blockquote>
