I can see online the trunk appears solid (some cars there is no metal behind the back seat). So the usual procedure would be to make a wooden adaptor, probably two pieces* of wood the same size:
- One with a 6x9 hole, and drill bolt holes to match the rear deck 6x9 holes
- The second with an 8" or 10"** subwoofer hole to mount the subwoofer to.
- Glue them together, THEN drill holes for the subwoofer bolts. Let dry. Add a cup of sugar and a tablespoon of butter, bake at 350 degrees. Just kidding!!!
(1) Drop bolts through the holes for the sub through from the top
(2) Bolt the assembly to the 6x9 holes
(3) Bolt the sub, using normal nuts to secure it in place and then nylon lock nuts after that due to vehicle vibration.
Wire them up (you need an amp with adjustable crossover if you don't have that already, and a highpass crossover for your fronts) and BLAST AWAY!!
*This could also be done with one thick piece and some routing. Part of the point is to make clearance for the sub to move forward.
**You need to see how wide the underside of the rear deck is to decide what size will fit. I would not get super heavy subwoofers, and if you carry a lot of stuff in the trunk consider slim low-profile subs.
