First thanks to Decware for making the plans free and also to all who have already posted, I learned a lot and actually found the guts to attempt this myself.

I have built a 12" WO moch up box.  Two 12" AB subs, nothing special.  I have a Rockford Fosgate 12" dual 2ohm HX2.  Just found another.  When it comes in I will build another WO for it.  I also need to get a table saw.  Had to use lots of glue and sealer on this initital try.

My main question is which direction to face it.  I have a hatchback.  Right now the WO only fits resting against the front seat backs.  This gives about 1/4" clearance to the hatch glass, and about 18" to the back of the car.  It can't slide back farther due to the angle of the glass.  Also for safety I wanted it up front so I could secure it to the roll bar with additional weld in brackets at the rear.  It also has to come out easily on track days.  Right now I have it facing forwards, which of course looks cool with the vent right at ear level between the seats. Might hang a styrofoam core mirror ball in the vent...

However with the longer throw of a horn would I be better off shooting it towards the back?

I am using 2 Cadence XAH250.2 amps to drive the subs, one on each sub.  Both amps are rated 500w RMS bridged into 4 ohms.  The AB 12s are single coil 4 ohm speakers.  The RF HX2s will be 4 ohms with the dual 2 ohm coils in series. Best I can tell Sealed area is 1.15Cuft after taking out the speaker displacement.  It will be a tad less with the RF HX2 which have a larger magnet structure.


Couple pics.  Again, no table saw, and not much in the way of wood working skills.  Now give me a wrench and it's a different story..

Laying out the pattern.


Subs in.  


Weather strip


Drew pattern on lid and marked walls in black for screw placement.


Lid on, starting the screws.  Went one screw every 1.5" to be safe on top. Every 2" on bottom.


And the car I'm squeeeezing it into...


Current location of WO and vent right behind driver's seat.


Incase my question got lost in the posting..

Thanks for any help!

Thanks.  I tried drawing out a 36x24 first but could not fit the 12" wooded diameter in the baffle.  I will look at it again.  I can cut down the height to we" even if I cut a shallow groove for the outermost edge of the subwoofer.   Though the support baffle would be very thin on the top and bottom.

Oh and yes, the joint is messed up.  Getting a table saw before i build a final version.
