I disagree with that statement, you can fit three 12's in there easily with the right kind of box.

yes you can do 3 in the hole. you can find a pic of the box with a search im sure. i could probably build you one if you told the specs of the speakers. let me know.

i found the specs and the mounting depth should be enough for a normal design. i attached a file of what the top piece would look like with 3 12s. as far as the design, i wont go into that. if you want to build it yourself, you can probably find the plans somewhere on the net.

Now if you were to make the box come out of the hole(which I already said in a previous post, that I guess nobody wanted to read) you should have no problem fitting three 12s, as long as you have the air space.
Now lets recap.
Three 12s in hole, no
Three 12s in hole and out of hole, yes

I designed, but never built a box as I described above...I may have to build it now...just to prove a point! However, fitting 4 12" subs requires cutting out part of the rear plastic that is in the rear hatch area. If you are talking about doing it without modification, than I believe that 3 will still fit...you would have to make the top plate angled towards the front of the car which would give you more mounting area. I will have to measure to make sure...if correct, I will post the actual dimensions and some measurements.

That fits flush in the well? Even with the gas tank?
I took a couple of pics. The first is my hatch pull down, if a 3rdgen doesnt have the auto pull down, is it smaller?
Heres the pic

Here is the pic of the distance between the edge of the hatch pull down and the edge of the well. There is only 12" if you were to stretch it a tad.

that box I bought off another member that was closing his shop (username mathew 3:16 or somthing) anyway, it fit in my 85 Iroc that didnt have the hatch pulldown, and it barely fit when the hatch was closed, high excursion subs wouldnt work in it. I tried it when I got my 89 Iroc, that has the hatch pull down, and It wouldnt slide all the way into the well. I think its because the back is a tad wider for the hatch pulldown, but I may be wrong. I am selling it because as you can see in my sig I am going with fiberglass to save weight and because I am only going to be running one sub.
