Help on positioning the box in my car

I'm going to be putting 2 15s in the backseat of my car. But I'm not sure what the best position for the subs and port will be. Ex. Subs up port back I think will be loudest. It's a small 4 door Corolla and the equipment will include 2 sa-15s off of a rockford amp. The box I am building will be 6 cubic ft tuned to 35hz.

Don't put it in the back seat. That is so ghetto

Tell me...does this smell like chloroform to you?

Why the backseat? Why not a wall? or the trunk?

Will not fit in the trunk. And its not going to be just sitting on the seat itself. Everything is coming out and I'm going to build a platform for the box to sit on that I can also bolt it down to. I also don't think I have enough experience to build a wall and tune it right. I live in albuquerque NM and there isn't a whole lot of knowledge floating around this area.

I would say subs up port back ( which will most likely be the best, but idk ), there is a bunch of options.

But if you go subs up port back and you dont like it you could flip it to try subs forward port up and subs back port up.......

I would also recommend making sure there is no air going into the trunk, you would probably lose some good output due to air leaks to the trunk if you dont seal the holes, gaps, ect. up.

Ok, so I think ill build the box like that and see what happens, if it doesn't sound right ill rebuild till I'm content. Right now the sub and port are firing from the backseat into the trunk and it slams hard for only 1 15. I do have the trunk sound deadened pretty well also. Does anyone have experience doing a backseat build like this?
