I have a 01 Acura MDX. I'm in the process of building a 12" sub box for a 12" OZ audio 12.2 matrix sub. I pulled the factory 10" sub & used the opening to get the most air space possible. Here are a few pics. I'm hopping to get more this weekend.
This is the mold already made & cut to size - I then sanded the corners smooth which the picture doesn't show. The speaker ring was made for a flush mount installation.
These pictures show the fleece already stretched & glassed. It was a pain to get the fleece wrinkles out. I added 3 layers of glass matt on the inside of the fleece vs. the outside. This makes it much easier to get a smoother finish. Next step is to get rid of the excess fleece & then start adding bondo to the outside. Not the best or most detailed pictures, but I hope you enjoy .
Here the box is coeated with 3m premium body filler. This stuff sands off real nice.
Here the box has been sanded smooth, primered & then I added putty to fill in the very small holes & indentations. I used bondo uv drying putty, which f'n ******. It was a pain to sand down & I eventually took it all off & had to primer again.
Back cup I ordered from parts from www.partsexpress.com
Checked sub for fitment.
Checked box for fitment in truck.
Unfortunately I over estimated the box size & Will be switching over to an IDQ which works great in small boxes.
