How's this box?

This box is for 2 12" Alpine Type-R's in the trunk of my Mustang. It's as big as i can go in every direction.

Is it enough airspace? port area? And is the back of the port too close to the back wall?

little more port area wouldnt hurt, try sliding port to one side and taking advantage of the .75 that the extra wall is using. (make port 4.75 wide, then adjust length to maintain tuning.)

my $0.02

i agree about making the slot port on either the left or right side of the box, and you should up the port area. a good rule of thumb is 12-16sq.in of port/ cubic foot.

yours is 50/4.7=10.6, shoot for something about 60 and it should keep the same sound as what you had and not have port noise..
