nope just your good old 2.3 lt 4cyl

the trunk is pretty big in size.

just need to get an idea on what the box would look like, witch ay to fire them ect....'

Fire the subs to the back of the trunk...if they can't fit, you'll have to settle for firing them up.

id say they would have to be fireing up.

my box for the 4 tens fits lightly snug. still have a good amount of room still deffinitaly can get a big ported box in there

Why not sell all your rockford's and buy 2 12" Fi Q's and put in them in a 4ft^3 NET box tuned to 33hz and sit back and drool?

Instead of trying to fight and get these to fit......With those MAX dimensions with 1/2" taken off each your right at 7 cubic ft......Whats your sub displacement?

Cut list, (you may want to try a different way) and you should double up the baffle:

0.75 (thick) in
1 Front, 1 Back: 22.5 (a) x 34.5 (d) in

1 Top, 1 Bottom: 6.5 (e) x 35 (h) in
0.75 (thick) in
2 Sides: 12 (g) x 35 (h) x 0.75 (thick) in

all in all those subs are not that great ported, you'd be better off getting a sub that likes ported boxes.
