It took a few months to finish. Had to work a lot and didnt have the motivation needed to finish up the job. But I finally got it done.
what i did have
The new box. 4.5 cuft tuned to 32 hz. Very fun to make.
I like silicone
Notice the 4" pvc waiting to be used
The box was very time consuming to make. I wanted to save as much cargo area as possible to I used every bit of space possible to readhewd my desired 4.5 cuft. The 'wings of the box extend over the wheel wells and it fits snuggly against the rear seat.
