Speaker Box trouble

Alright people im having some issues, first off i got a 1995 Oldsmobile Aurora, unfortunitly my back see does not fold down except fora small portion which is the armrest in the back seat, that is my only ventilation from the back to the front, now here is my delima, i got 2 12" PBX subs and a ASA-1000.1D Amp, but i can not find the right box for the car, everything i use just isnt up to what it should be, so i need suggestions on a box style....im tryin to get into the competition world and right now im not looking for like 1st place system just something decent, but if you could reply the style you think would work best in my trunk

Subs up in a SEALED box.... What is the total space you can give up in the trunk..... Height Width and Length?

For SQ I'd say Jimbo is on the right track.

If you were going to compete SPL I can tell you we built a bandpass enclosure a while back with a single port coming through that hole where the armrest is. It slammed HARD But it was a little bit of a one note wonder.

Thanks John... LOL i figured since it was in the SQ section that is what he was looking for.

Now on the SPL side of things.... HELL YEAH... John is right.

this car has a subwoofer in back deck take it out and take insolator out of the arm rest you can port thru both of these or go seald beware this car has a big trunk but smaal opening you might half to build box in the car check out myprofile pic to see my arura with a solox 18
