Ive got an orion h2 15" putting it in the back of my 2 door 1992 chevy s-10 blazer. Probably could make a box big enough to fit it horizantilly but in case which should i make the box for. Facing upwards or horizantal?
As long as the box is the right size... it shouldn't matter. I have 2 12's under the seat of a boat... the subs cones are facing up... and there fine.
each vehicles dynamics are different, but from my expeience you will get more bass the longer you can make the air chamber..most of the time, you will get a longer air chamber by pointing the sub to the rear of the vehicle and then having it reflect back up to you the driver...another option is downward facing subs...sometimes they actually sound better than rear or up.
