word yo....the cheaper the better apparently.

but to the OP...if i were in your shoes, i would do about a 9 cubic foot ported box with PSP aeroports and tuned to around 35htz.

Great box...

But it doesn't seem like there's enough space to downfire?

But I'm not sure. Could be a camera trick. To OP:

As they said before, a 9 CuFt box tuned to 35hz.

You can find a lot of calculators online that tell you what size your port should be in accordance to how wide it is... for instance, two 6" wide ports should be about 10" long to achieve 35hz tuning with a 9cuft box.

If you want, you can measure how wide the inside of your car is (making sure your doors close, of course), from your window down, and from where your window and rear seat intersect, back about 3 inches and from that point to the back of your cab... one of us will make a quick sketch of what it should look like.
