You don't think you'll have room to face it backward? I'd think you should have plenty enough room... In these cars (and in my experience), orienting the enclosure to be sub-back port-back is the way to go. That is, if you aren't willing to give up your back seat and seal the box off to the cabin... then you'd want to go sub-forward port-forward

I have a Grand Prix. I haven't read through all the replies yet, but this caught my eye. The trunk itself, yes, is very wide and very large. However, the trunk opening is deceivingly narrow. Trust me on this. I had trouble fitting my 2.25 cuft ported box in the trunk (not saying fitting that size box in is hard, but I didn't think through the measurements very well), and I can tell you for sure, if you want to put a box in there that will really let the 18" breathe, you'll need to build it in the trunk. You're best off getting 2 12"s just like practically everyone else here has said.
