box design firing which way?

[chrisw91]

ive seen this posted many times. im curious if there is a general suggestion for this though. 4 door car with sub in trunk, what is the best way to have the sub/port firing? im going to be making a box for a toyota corolla, just wondering which way is best...

sub and port back
sub forward with port to the side
both would work well...only do both firing forward if it's completely sealed off around the box
